The younger ones have magnetic irons in their brain that helps them in navigating. [88] Loggerheads may mistake the floating plastic for jellyfish, a common food item. [96] Greece's ARCHELON works for their conservation. In the United States, the loggerhead sea turtle is the official state reptile of South Carolina and also the state saltwater reptile of Florida. [37], Juvenile loggerheads share the Sargassum habitat with a variety of other organisms. It has a greater list of known prey than any other sea turtle. Females are also susceptible to mosquitoes and flesh flies. Most notably, the magnificent Loggerhead Sea Turtle remains the largest hard-shelled turtle. Female-female aggression is common, both in the wild and in captivity. [51] On Bald Head Island in North Carolina, wire mesh screens are used on every confirmed nest to prevent excavation by resident red foxes. Next, the male and female begin to circle each other. Turtles ingest a wide array of this floating debris, including bags, sheets, pellets, balloons and abandoned fishing line. At night, captives sleep in the same position with their eyes tightly shut, and are slow to react. Researchers have found that an increase of temperature causes feeding grounds to produce more food (Marn et al., 2017). It is exceeded in length and weight only by the leatherback sea turtle. [13] Five vertebral scutes run down the carapace's midline, while five pairs of costal scutes border them. [62] During their seasonal migration, juvenile loggerheads have the ability to use both magnetic and visual cues. Many researchers agree that temperature increases due to climate change has a complicated impact on turtles. This turtle is named for its very large head. No external differences in sex are seen until the turtle becomes an adult, the most obvious difference being the adult males have thicker tails and shorter plastrons (lower shells) than the females. [87] They also become stuck in traps, pots, trawls, and dredges. As you keep reading, you will learn about 35+ amazing facts of these mysterious and coolest surfers in the sea. [38], Loggerhead sea turtles observed in captivity and in the wild are most active during the day. [52], Annual variations in climatic temperatures can affect sex ratios, since loggerheads have temperature-dependent sex determination. It is a marine reptile, belonging to the family Cheloniidae. [82], Loggerhead sea turtles were once intensively hunted for their meat and eggs; consumption has decreased, however, due to worldwide legislation. Sea Turtle Conservancy 4581 NW 6th St, Suite A Gainesville, FL 32609 Phone: 352-373-6441 Fax: 352-375-2449 stc@conserveturtles.org Females return to lay eggs at intervals of 12–17 days during the nesting season, on or near the beach where they hatched. [25] Pacific loggerheads occasionally nest in Vanuatu and Tokelau. Although found in many parts of the world, the loggerhead’s conservation status is ‘Vulnerable’. [64], Like all marine turtles, the loggerhead prepares for reproduction in its foraging area. [24] The largest Indian Ocean nesting site is Oman, on the Arabian Peninsula, which hosts around 15,000 nests, giving it the second largest nesting population of loggerheads in the world. Loggerhead Sea Turtle. Further, only the Leatherback Sea Turtle, which lacks a hard shell, exceeds it in terms of sheer size. In the following article you can read about some interesting sea turtle facts for kids. It spends most of its life in saltwater and estuarine habitats, with females briefly coming ashore to lay eggs. As compared to different species of marine turtles, loggerhead turtles have larger heads. [49], Fibropapillomatosis disease caused by a form of the herpes-type virus threatens loggerheads with internal and external tumors. The loggerhead takes on a floating, cold-stunned posture when temperatures drop to around 10 °C (50 °F). Like other sea turtles, the loggerhead has a relatively lengthy life span—the species can live from 47 to 67 years in the wild. Aggressive efforts to protect nesting sites by covering them with wire mesh has significantly reduced the impact of raccoon predation on loggerhead sea turtle eggs. Efforts are underway to find a nonmagnetic material that will prevent predators gnawing through the barrier. Quick Facts: Loggerhead sea turtles have pale underbellies Loggerheads have claws on their flippers Loggerhead sea turtle eggs incubate in 60 days. They are less likely to be hunted for their meat or shell compared to other sea turtles. Facts-Evidence shows that turtle’s existed during the time of dinosaurs, which was about 200 million years ago (Sunset Beach Turtle Watch Program, 2004).-The eggshells of loggerhead turtles is composed of calcium that female loggerheads store in their shell (Malory, 2013). This takes place several years before the loggerhead migrates to a mating area. Very few loggerheads are found along the European and African coastlines. Eastern Australia and Japan are the major nesting areas, with the Great Barrier Reef deemed an important nesting area. The females then cover the egg chamber and body pit with sand, and finally return to the sea. Juveniles are more frequently found in shallow estuarine habitats with limited ocean access compared to non-nesting adults. [56], Hatchlings range in color from light brown to almost black, lacking the adult's distinct yellows and reds. The loggerhead sea turtle is the world's largest hard-shelled turtle, slightly larger at average and maximum mature weights than the green sea turtle and the Galapagos tortoise. [60] They initially use the undertow to push them five to 10 m away from the shore. Once the turtles reach adulthood, their formidable size limits predation to large marine animals, such as sharks. In one coastal section in eastern Australia during the 1970s, predation of turtle eggs destroyed up to 95% of all clutches laid. [23] Along the African coastline, loggerheads nest from Mozambique's Bazaruto Archipelago to South Africa's St Lucia estuary. [68] Before mating, the male approaches a female and attempts to mount her, while she resists. The result was a complete isolation of the Atlantic and Pacific populations of loggerheads. [86] Many juvenile loggerheads aggregate off the coast of Baja California Sur, Mexico, where small coastal fisheries increase these turtles' mortality risk; fishers have reported catching dozens of loggerheads with bottom-set gear per day per boat. They are also found in the Mediterranean Sea. The carapaces of males are wider and less domed than the females', and males typically have wider heads than females. [83] In Mexico, turtle eggs are a common meal; locals claim the egg is an aphrodisiac. [71], All sea turtles have similar basic nesting behaviors. Loggerhead sea turtles are most active during the day. The loggerhead is carnivorous and prefers coastal marine environments. The adult loggerhead sea turtle weighs approximately 135 kg (298 lb), with the largest specimens weighing in at more than 450 kg (1,000 lb). It is also the world's second largest extant turtle after the leatherback sea turtle. Graphic Credit - NOAA, Jack Javech. At low temperatures, loggerheads can't digest food. Females only lay eggs every two or three years. Here are 21 interesting and fun facts you may not have learned about the loggerhead sea turtle: 1. Loggerhead turtles generally have a shell that is about three feet long and usually weight about 250 pounds. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. They depend entirely on this method of swimming by one year old. Their bodies are similarly large, earning them the title of the largest hard-shelled sea turtle. [12] Caught in this unattended equipment, loggerheads risk serious injury or drowning. Around three million years ago, during the Pliocene epoch, Central America emerged from the sea, effectively cutting off currents between the Atlantic and Indo-Pacific Oceans. Since the loggerhead occupies such a broad range, successful conservation requires efforts from multiple countries. The prolonged time required for loggerheads to reach sexual maturity and the high mortality rates of eggs and young turtles from natural phenomena compound the problems of population reduction as a consequence of human activities. [4][13] Thirty-five other names emerged over the following two centuries, with the combination Caretta caretta first introduced in 1873 by Leonhard Stejneger. Some Exciting Facts about Loggerhead Sea Turtle. Record Holder. With the exception of the leatherback sea turtle, all sea turtles (including the loggerhead) belong to the family Chelondiidae. [34] Adults and juveniles live along the continental shelf as well as in shallow coastal estuaries. Conservation. [14] The nuchal scute is located at the base of the head. [92] A more localized effect on gender skewing comes from the construction of tall buildings, which reduce sun exposure, lowering the average sand temperature, which results in a shift in gender ratios to favor the emergence of male turtles. Other food items include sponges, corals, sea pens, polychaete worms, sea anemones, cephalopods, barnacles, brachiopods, isopods, Portuguese men o' war, insects, bryozoans, sea urchins, sand dollars, sea cucumbers, starfish, fish (eggs, juveniles, and adults), hatchling turtles (including members of its own species), algae, and vascular plants. Optimum nesting beaches are open-sand beaches above the high-tide line. They also eat softer foods like jellyfish, fish, seaweed, and a brown algae called sargassum. This helps them to never get lost and always find the way back to their place of birth. These types of sea turtles are linked to the family of Cheloniidae. These sea turtles, like many sea turtle species, are threatened with extinction.. Because higher aggression is metabolically costly and potentially debilitating, contact is much more likely to escalate when the conflict is over access to good foraging grounds. Although worldwide legislation protects sea turtles, their meat and eggs are consumed where laws aren't enforced. The mats of Sargassum contain as many as 100 different species of animals on which the juveniles feed. At all stages, an upright tail shows willingness to escalate, while a curled tail shows willingness to submit. They rarely come ashore besides the females' brief visits to construct nests and deposit eggs. Despite this, turtle meat and eggs are still consumed in countries where regulations are not strictly enforced. Turtle excluder devices for nets and other traps reduce the number being accidentally caught. Quick facts about the second largest sea turtle in the world! The average loggerhead measures around 90 cm (35 in) in carapacelength when fully grown. Appearance of Loggerhead Sea Turtles. Ten Loggerhead Sea Turtle Facts 1. Sea turtles can stay under water for up to five hours.The leatherback sea turtle has been recorded swimming as fast as 22 mph (35 km/h), according to the San Diego Zoo.Loggerhead sea turtles drink salt water and excrete excess salt through glands by their eyes, which makes them look like they are crying.Young flatback sea turtles sleep on the surface of the water.Additional resources 1. Young loggerheads are exploited by numerous predators; the eggs are especially vulnerable to terrestrial organisms. For the moment, the IUCN currently lists the impressive species as Vulnerable. Loggerhead Sea Turtles’ carapace, or shell that can grow to be about 2.5 feet to 3.5 feet. While nesting, females produce an average of 3.9 egg clutches, and then become quiescent, producing no eggs for two to three years. The average loggerhead measures around 90 cm (35 in) in carapace length when fully grown. Out of the total seven sea turtle species, six are threatened with extinction due to human activities. We are talking about their jaws. The Loggerhead sea turtle is classified as endangered by the IUCN (International Union for the Conservation of Nature and Natural Resources). [28], The Mediterranean Sea is a nursery for juveniles, as well as a common place for adults in the spring and summer months. They are found throughout both temperate and tropical waters. Nesting females are hunted by dogs and sometimes humans. [23] North Atlantic and Mediterranean loggerhead sea turtles are descendants of colonizing loggerheads from Tongaland, South Africa. Despite the fact that more than 80% of nesting occurs within protected areas in Australia, the loggerhead turtle population in the early stages of decline for the south-west Pacific stock though stable in Western Australia. These points can be used as "pseudo-claws" to tear large pieces of food in the loggerhead's mouth. The loggerhead sea turtle is the South Carolina state reptile (designated in 1988) and is the most commonly observed sea turtle off the SC coast. Loggerhead Sea Turtle Facts. [45][49], In Australia, the introduction of the red fox (Vulpes vulpes) by British settlers in the 19th century led to significant reductions in loggerhead sea turtle populations. [54], More than 100 species of animals from 13 phyla, as well as 37 kinds of algae, live on loggerheads' backs. Artificial lighting confuses hatchlings, interfering with their ability to find water. The loggerhead sea turtle inhabits the temperate and tropical zones of the world with waters that have temperatures between 13° to 28° C (56-82° F). Caretta caretta. The temperature of the nest determines the sex of the hatchlings. As a result, they can easily crush their prey like lobsters and crabs. Hatchlings are brown or black, while adults have yellow or brown skin and reddish brown shells. The Cape Verde Islands are the only significant nesting site on the eastern side of the Atlantic. With their hind limbs, they excavate an egg chamber in which the eggs are deposited. The skull of the loggerhead is broad and massive, providing an anchor for the strong jaw muscles that are needed to crush shellfish. [70] In the Northern Hemisphere, loggerheads mate from late March to early June. Turtle excluder devices have been implemented in efforts to reduce mortality by providing an escape route for the turtles. The greatest threat is loss of nesting habitat due to coastal development, predation of nests, and human disturbances (such as coastal lighting and housing developments) that cause disorientations during the emergence of hatchlings. [31] In addition to the Greek coast, the coastlines of Cyprus and Turkey are also common nesting sites. The loggerhead sea turtle is found in the Atlantic, Pacific, and Indian Oceans, as well as the Mediterranean Sea. Like all other sea turtles except the leatherback, loggerheads are members of the ancient family Cheloniidae, and appeared about 40 million years ago. The amount of food also has a relationship to temperature. [16], Lachrymal glands located behind each eye allow the loggerhead to maintain osmotic balance by eliminating the excess salt obtained from ingesting ocean water. Loggerhead turtles are named for their large heads that support powerful jaw muscles, allowing them to crush hard-shelled prey like clams and sea urchins. Leatherbacks prey only on jellyfish and other soft-bodied animals. LMC is one of 12 sea turtle rehabilitation facilities in the State. The green sea turtle gets its name from the color of its body fat. Habitat destruction from human encroachment deprives turtles of nesting sites. Many hatchlings use Sargassum in the open ocean as protection until they reach 45 cm (18 in). [69] The nesting area must be selected carefully because it affects characteristics such as fitness, emergence ratio, and vulnerability to nest predators. Prey found in Sargassum mats may include barnacles, crab larvae, fish eggs, and hydrozoan colonies. The loggerhead turtle (Caretta caretta), is an oceanic turtle that is widely distributed across the different continents of the world. 2. [60] Once in the ocean, they swim for about 20 hours, taking them far offshore. [12], In many places during the nesting season, workers and volunteers search the coastline for nests,[100] and researchers may also go out during the evening to look for nesting females for tagging studies and gather barnacles and tissues samples. TEDs are mandatory for all shrimp trawlers. Although found in many parts of the world, the loggerhead’s conservation status is ‘Vulnerable’. Efforts to restore their numbers will require international cooperation, since the turtles roam vast areas of ocean and critical nesting beaches are scattered across several countries. Interesting Facts: The loggerhead is thought to be the largest living hard-shelled turtle. [11] The turtle's neck and sides are brown on the tops and yellow on the sides and bottom. Many animals prey upon loggerhead turtles. Interesting Facts: The loggerhead is thought to be the largest living hard-shelled turtle. ", "Archelon, the Sea Turtle Protection Society of Greece: 21 Years Studying and Protecting Sea Turtles", "Legislative instrument details: Cartagena Convention", "State symbols/Fla. No external differences in sex are see… The main danger for Loggerheads now is the nets used by fishermen which can accidentally kill the turtles. [41] In February 2015, a live loggerhead turtle was found floating in British Columbian waters of 10.5 °C (50.9 °F) with extensive algal growth on its carapace. Loggerhead turtles sometimes breed and produce fertile hybrids with related species, such as the green sea turtle, hawksbill sea turtle, and Kemp's ridley sea turtle. Further, only the Leatherback Sea Turtle, which lacks a hard shell, exceeds it in terms of sheer size. Loggerhead Sea Turtle Facts. The Loggerhead sea turtle is the largest hard-shelled turtle in the world. [12][76] The loggerhead sea turtle belongs to the family Cheloniidae, which includes all extant sea turtles except the leatherback sea turtle. Females lay three to five nests, sometimes more, during a single nesting season. [26] The return journey to the natal beaches in Japan has been long suspected, although the trip would cross unproductive clear water with few feeding opportunities. The Convention on Migratory Species works for the conservation of loggerhead sea turtles on the Atlantic coast of Africa, as well as in the Indian Ocean and southeast Asia. Most notably, the magnificent Loggerhead Sea Turtle remains the largest hard-shelled turtle. All six sea turtle species found in U.S. waters are protected by the Endangered Species Act.They are the green, hawksbill, Kemp's ridley, leatherback, loggerhead, and olive ridley. [50] Aggressive efforts to destroy foxes in the 1980s and 1990s has reduced this impact; however, it is estimated that it will be the year 2020 before populations will experience complete recovery from such dramatic losses.[51]. Facts-Evidence shows that turtle’s existed during the time of dinosaurs, which was about 200 million years ago (Sunset Beach Turtle Watch Program, 2004).-The eggshells of loggerhead turtles is composed of calcium that female loggerheads store in their shell (Malory, 2013). [30] Because of this, Greek authorities do not allow planes to take off or land at night in Zakynthos due to the nesting turtles. [69] Construction of new thermal power stations can raise local water temperature, which is also said to be a threat.[93]. Temperatures from 27–28 °C (81–82 °F) are most suitable for nesting females. Loggerhead sea turtles use their very … The eggs are laid near the water so the hatchlings can return to the sea. However, much larger loggerheads have been reported. [22] One interesting fact about loggerhead sea turtles is that they are the largest of the soft shelled sea turtle species. The IUCN Red List classifies the loggerhead turtle as "vulnerable." Caretta caretta. Once in the water, loggerhead turtles use magnetite in their brains and Earth's magnetic field for navigation. [20], The loggerhead sea turtle has a cosmopolitan distribution, nesting over the broadest geographical range of any sea turtle. [43] First, initial contact is stimulated by visual or tactile cues. Sea Turtle Facts for Kids – Discover the Ancient Creatures Learn about sea turtles. Fungi such as Penicillium infect loggerhead sea turtle nests and cloacae. Loggerhead Sea Turtles are primarily carnivores. The size of the population is decreasing. WWF tracks sea turtles to know more about their movements and routes from feeding to breeding grounds to other activities. Its (scientific) name is Caretta caretta. In this respect, human development may aid turtles, as nests shaded by tall buildings are cooler and produce more males. [49], Infectious bacteria such as Pseudomonas and Salmonella attack loggerhead hatchlings and eggs. [57] Loggerhead hatchlings are drawn toward the brighter area over the water which is the consequence of the reflection of moon and star light. The loggerhead sea turtle was listed as threatened in 1978 under the Endangered Species Act and has received federal protection ever since. The Loggerhead Sea Turtle’s average lifespan in the wild is 50 or more years, is a Carnivore and is vulnerable. They also have strong, muscular jaws. Six of them (the hawksbill, green, flatback, loggerhead, Kemp's ridley, and olive ridley turtles) have shells made up of hard scutes, while the aptly-named leatherback turtle is in the Family Dermochelyidae and has a leathery carapace made up of connective tissue. Eggs and nestlings are prey to snakes, birds, mammals (including humans), lizards, insects, crabs, and worms. [72] A single clutch may have as many as seven fathers, each contributing sperm to a portion of the clutch. [24] They forage in the East China Sea, the southwestern Pacific, and along the Baja California Peninsula. [81] During the most recent ice age, the beaches of southeastern North America were too cold for sea turtle eggs. [1] Of the six species of living Cheloniidae, loggerheads are more closely related to the Kemp's ridley sea turtle, olive ridley sea turtle, and the hawksbill turtle than they are to the flatback turtle and the green turtle. Nesting extends as far north as Virginia, as far south as Brazil, and as far east as the Cape Verde Islands. Let's get involved in all these significant loggerhead turtle facts including loggerhead turtles diet, habitat, distribution, and reproduction. [57] Loggerheads have an average clutch size of 112.4 eggs. Loggerhead Sea Turtle Facts. The ingested plastic causes numerous health concerns, including intestinal blockage, reduced nutrient absorption and malnutrition, suffocation, ulcerations, or starvation. [23], Pacific loggerheads live in temperate to tropical regions. [77] The subspecific classification of the loggerhead sea turtle is debated, but most authors consider it a single polymorphic species. [12], Loggerhead sea turtles are classified as vulnerable by the International Union for the Conservation of Nature and are listed under Appendix I of the Convention on International Trade in Endangered Species, making international trade illegal. Loggerhead turtle facts for kids: learn all about these top turtles, with facts about loggerhead turtle migration, habitat, diet and behaviour. At higher temperatures, females are favored. [84] Eating turtle eggs or meat can cause serious illness due to harmful bacteria, such as Pseudomonas aeruginosa and Serratia marcescens, and high levels of toxic metals that build up through bioaccumulation. [86] The most common commercial fishery that accidentally takes loggerheads are bottom trawls used for shrimp vessels in the Gulf of California. One posits that males favor large females because of their perceived higher fecundity (ability to reproduce). She has taught science courses at the high school, college, and graduate levels. Many turtles die as bycatch or drown from entanglement in fishing lines and nets. [21], In the Indian Ocean, loggerheads feed along the coastlines of Africa, the Arabian Peninsula, and in the Arabian Sea. [11] An iron compound, magnetite, in their brains allows the turtles to perceive the Earth's magnetic field,[61] for navigation. Many other parasites and several infectious diseases affect loggerheads. [8][9][10] Adults have an average weight range of 80 to 200 kg (180 to 440 lb), averaging about 135 kg (298 lb), and a straight-line carapace length range of 70 to 95 cm (28 to 37 in). [70] Through the act of mating, the female ovulates eggs which are fertilized by the male. While resting, they spread their forelimbs to about midstroke swimming position. The average adult is about 90 cm (35 in) long and weighs around 135 kg (298 lb). Name: The loggerhead sea turtle owes its name to its large head (which grows up to 10 inches / 25 centimeters wide).The head is also equipped with two powerful jaws used to crush the shells of molluscs and crustaceans. At breeding sites when a loggerhead turtle lays multiple clutches in a season, a higher temperature will cause the duration of time between laying two different nests to become shorter. In the ocean, predators of the loggerhead juveniles include portunid crabs and various fishes, such as parrotfishes and moray eels. [98] Annex 2 of the Specially Protected Areas and Wildlife Protocol of the Cartagena Convention, which deals with pollution that could harm marine ecosystems, also protects them. [8] The maximum reported weight is 545 kg (1,202 lb) and the maximum (presumed total) length is 213 cm (84 in). Photo Credit: NOAA, via Wikimedia CommonsFemale loggerheads produce and bury an The average duration of dives is 15–30 min, but they can stay submerged for up to four hours. Fishing gear is the biggest threat to loggerheads in the open ocean. Some of these species live up to 100 years! In total, 9 distinct population segments are under the protection of the Endangered Species Act of 1973, with 4 population segments classified as "threatened" and 5 classified as "endangered"[6] Adults are more rarely attacked due to their large size, but may be preyed on by large sharks, seals, and killer whales. Nesting sites along the eastern Pacific Basin are rare. Commercial trade of loggerheads or derived products is prohibited by CITES Appendix I. If the male has competitors, the female may let the males struggle with each other. cracker horse/loggerhead turtle (SB 230)", "Trans-Pacific migrations of the loggerhead turtle (, "Synopsis of the Biological Data on the Loggerhead Sea Turtle, "Climate change and temperature-dependent sex determination inreptiles", "Effects of exposure to artificial lighting on orientation of hatchling sea turtles on the beach and in the ocean", "Environmental effects on growth, reporduction, and life-history traits of loggerhead turtles ("Caretta caretta")", "Sea Turtles of the World: an Annotated and Illustrated Catalogue of Sea Turtle Species Known to Date", "Nest site selection, oviposition, eggs, development, hatching and emergence of loggerhead turtles", "Critical periods and pivotal temperatures for sexual differentiation in loggerhead sea turtles", turtles of the world 2017 update: Annotated checklist and atlas of taxonomy, synonymy, distribution, and conservation status, https://en.wikipedia.org/w/index.php?title=Loggerhead_sea_turtle&oldid=991131324, Pages containing links to subscription-only content, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License, This page was last edited on 28 November 2020, at 12:30.
