Leatherback Sea Turtle Research Papers

The leatherback is an endangered species. It's also the largest sea turtle. Adults usually weigh about 800 to 1,000 pounds (363 to 454 kilograms). Some have been reported to weigh as much as 2,000 pounds (907 kilograms). The turtles get their name because their backs are covered with leathery, oily tissue instead of a shell.

In particular, one of these seven species is comprised of the loggerhead sea turtle (Caretta caretta). The largest of all hard-shelled turtles, loggerheads have massive heads, strong jaws, and a reddish-brown shell, or carapace. Their front flippers are short and thick with 2 claws, while the rear flippers can have 2 or 3 claws. Loggerhead hatchlings have a dark-brown carapace with pale brown flippers. According to National Geographic (2015), adult males reach about three feet (nearly one meter) in shell length and weigh about 250 pounds (113 kilograms), but large specimens of more than 1,000 pounds (454 kilograms) have been found. They are primarily carnivores, munching jellyfish, conchs, crabs, and even fish, but will eat seaweed occasionally. They prefer to feed in coastal bays and estuaries, as well as the shallow water along the continental shelves of the Atlantic, Pacific and Indian Oceans.

The Red Eared Slider is one of the most common Mid-South East Coast. They can be found in marshes, ponds, and slow moving bodies of water. Other species of turtles include: Eastern Box Turtle, Common Snapping Turtles, Eastern Painted Turtle, Red Bellied, Bog Turtle, Spotted Turtle, Musk Turtle, Eastern

Ranging from the Rocky Mountains eastward to the Mississippi River, the ornate box turtle, Terrapene ornata, is the western counterpart of the common box turtle, a group of species and subspecies known collectively as Terrapene carolina. Formally described by Swiss-American biologist Louis Agassiz (1807–1873) in 1857, T. ornata is native

The lifespan of loggerhead sea turtles (Caretta caretta) can be divided into three classifications: hatchlings, juveniles, and adults. Within these classifications are several stages that loggerhead turtles undergo that are characterized by changes in behavior, morphology, or location. There are various ways to define and classify these stages. Loggerhead sea turtles have abrupt developmental changes in regards to their behavior, habitat, and use of resources as they mature (Dodd 1988). The loggerhead sea turtle life cycle starts with oviposition on the nesting beach. Shortly after oviposition, the neural groove and head fold forms, the amnion arises, and the number of somites increases. As development continues, the heart begins beating, the

Soft shell turtles are different from other turtles because of their diet, behavior, and habitat.

The loggerhead turtle (Caretta caretta) distributed in all of the world’s tropical and temperate oceans, consists of 10 subpopulations based on biological and geographical traits. In 2013, 6 of 10 subpopulations have been assessed to estimate global population trend based on 3-generation change (approximately 10-50 years) of nest number as

Dry, hot, and surrounded by an eerily empty desert, two lone sea turtle lie dormant in their shells sizzling

Powerful and aggressive, the common snapping turtle, Chelydra serpentina, is a heavy-bodied species with a distinctive prehistoric aspect. The genus name, Chelydra, means “water serpent,” while the species name, serpentina, means “snake-like” (Ernst, et al., n.d.). A member of the chelonian family Chelydridae, the common snapping turtle was formally described in

Leatherback turtles have the most hydrodynamic body design of any sea turtle, with a large, teardrop-shaped body. A large pair of front flippers powers the turtles through the water. Like other sea turtles, the leatherback has flattened fore limbs adapted for swimming in the open ocean. Claws are absent from both pairs of flippers. Leatherback's front flippers can grow up to 2.7 m (8.9 ft) in large specimens, the largest flippers (even in comparison to its body) of any sea turtle. The leatherback has several features that distinguish it from other sea turtles. Its most notable feature is the lack of a bony carapace. Seven distinct ridges rise from the carapace, crossing from the anterior to posterior margin of the turtle's back. Leatherbacks

There was also bright lights, creating a very well lit and warm environment for everything inside The turtles in the terrarium included the western painted turtle, which is the most widespread native turtle of North America. The western painted feeds mostly on plants and small animals like fish, and insects. They are normally four to ten inches long and the only species of the Chrysemys species, part of the pond turtle family. This turtle is identified by its red bottom. There was also the red eared turtle which eats feeds on plants and smaller animals similar to the western painted, but also crickets, snails, and tadpoles. They are identified by their red ears and belong to the Emydidae family, a subspecies of the pond slider. Native to the southern United States and northern Mexico, but has been successfully introduced into Nebraska ranging from six to twelve inches in size. The third species of turtle in the terrarium was the yellow mud turtle which are omnivorous eating worms, crayfish, and aquatic insects, where they also forage in water and on land for their food. They are easily identified by their yellow appearance, smaller average size of six inches and are part of the Kinosternidae family found in Central United States and

Leatherback Turtles By:Isabella Zosel Leatherback turtles are listed as endangered on the species at risk list in canada and are on the endangered species list in the united states. This is because there is only an estimated 34,000-36,000 female leatherback turtle in the world (male population can’t be known because they stay underwater at all times.) WHat is causing this is egg collection, fishing/netting, and human activity on beaches/ human pollution.

Leatherbacks are the species that most people are thinking of when they think of sea turtles. They are the biggest and most migratory of all sea turtles, but they are becoming extremely endangered due to poaching, pollutants, and other killers even though we have tried many things to stop it. We have done many things to protect sea turtles, but some people don’t follow the rules and come closer every day to extinguishing the leatherbacks. People have to stop killing leatherbacks for sport unless they want a whole marine ecosystem to be put off scale.

After millions of years of being endangered in war-torn coast of southern Lebanon, Mediterranean sea turtles were finally protected by two women, Mona Khalil and Habiba Fayed, who opened a bed-and breakfast and with the help of the guests, protected turtles’ eggs by burying an iron grid in the sand above the eggs.
