How Does Natural Selection Shape The Leatherback Sea Turtle

They are known for being active. They are known for being active because turtles are usually slow and it’s fun to watch them as they move and slide into the water and onto the rocks. Your turtle is going to move a lot when they get comfortable with their tank, so you won’t just see them not moving, they will always move. They will be hanging around the rocks you put in the tank with them because, to them rocks mean “comfortable” to them.

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.

The Crucible In the 1958 “The Crucible’’ there’s plenty of different universal themes that apply to everyone. But a very common and consecutive theme that re-occurs several times in The Crucible is “Lies and Deceit.” For a God following village there sure is a lot of lying and deceiving. One of the main examples of this theme would be Abigail.

The green sea turtle occurs throughout tropical and subtropical oceans and is among the largest of the hard-shelled sea turtles growing to as much as 440 pounds and four feet in length. The breeding populations in Florida were listed as endangered in 1978 (43 FR 32800 32811, July 28, 1978) whereas all other populations were listed as threatened (NOAA 2015h). There is a proposal for identification of a North Atlantic green sea turtle distinct population that would be listed as threatened, continuing its current listing status near New York (80 FR 51763 51764, August 26, 2015). They are found in the shallow waters (except during migration) of shoals, bays, lagoons reefs, and inlets, often where submerged aquatic vegetation exists, from Maine south to Florida, and throughout the Gulf of Mexico and the Caribbean Sea (USFWS 2015n, 2015o; NOAA 2015e). Green sea turtles nests are not present in New York; however, they occasionally are found stranded on or near the shore (NYSDEC 2015ad). Breeding takes places in subtropical to tropical oceans every two, three, or four years between June and September, with peak nesting in June and July (NOAA 2015h; USFWS 2015u). Hatching usually occurs at night, and many green sea turtle hatchlings seek refuge and food in masses of floating sea plants (USFWS

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.

Loggerhead sea turtles are one of the most abundant species of the marine life in the U.S. oceans but the population is currently decreasing due to pollution increase and getting caught in bycatch. The term bycatch is when shrimp fishermen have their nets out and the animal ( in this case a loggerhead sea turtle) gets caught in the net and eventually killing the sea turtle . ((( Add More))))

Logger Head Turtles are primarily carnivores for most of their lives, meaning they mainly eat other animals (Marine Bio, 2015). Hatchlings mostly eat sponges, jellyfish, sargassum weed, small gastropods and crustaceans (Marine Bio, 2015). Juveniles, sub-adults and adults feed on conch, clams, horseshoe crabs, as well as other crustaceans (Marine Bio, 2015). As the turtles grow, their jaws get stronger (Harrison, 2005). This helps them to eat much firmer food such as Horseshoe crabs and clams (Harrison, 2005). The loggerhead turtle sexual maturity is reached between 22 to 27 years of age (Environment, 2001). While it is not clear how long a juvenile loggerhead turtle will stay in the open ocean, once it moves to its feeding

The loggerhead sea turtle, Caretta caretta, is a threatened species with a highly migratory behavior and shifting habitat requirements depending on maturity (NMFS and USFWS 1998). The loggerhead nesting grounds are typically in warm temperate regions (NMFS and USFWS 1998).

National Oceanic and Atmospheric Administration scientists Tomo Eguchi and Jeff Seminoff made oceanic history by releasing the first juvenile loggerhead sea turtle into the West Coast of the United States, with a transmitter attacked to its body. This exploration is going to aid scientists in getting a better understanding of what type of habitats juvenile loggerheads live in prior to participating in the years prior to participation in migration. Scientists are hopping to gain a better understanding of where juvenile loggerheads live for the sake protecting their habitats from fisherman. As of now, scientists have predicted that juvenile loggerheads tend to inhabit the same environments as swordfish. This is extremely dangerous to the lives of sea turtles considering that swordfish are heavily hunted by many fishermen. Therefore, if scientist theories are correct, the loggerheads are living in very dangerous environments. This exploration was initiated when a Coast Guard vessel found the loggerhead and took it to the Aquarium of the Pacific, where it would receive medical attention.

Kemp's Ridley sea turtles are fascinating. Not many animals lay 200-300 eggs a year and are still considered endangered. Even though Kemp's Ridley sea turtles lay many eggs their population is small, how can this be?

When my brother and me were little we would get baby soft shell turtles from the River and keep them as pets.

The sea turtle mainly uses aquatic locomotion. THe leatherback sea turtle swims in the ocean for most of their lives. However, females swim ashore to deposit their eggs. Leatherback sea turtles have a flatter shell which enhances their swimming abilities. Because of the sea turtles prowess as a swimmer, their land-navigating ability is decreased and makes them slow-moving on land. When they are in water they can reach speeds of up to 20 miles per hour (mph) which can allow for a quick escape since leatherbacks have a softer shell than the other species of sea turtle.

There are seven extant species of sea turtles, six of which are listed as endangered or critically endangered by the International Union for Conservation of Nature, and all of which are included in CITES (IUCN, 2015), (CITES, 2017). Sea turtles lay large clutches of eggs as an evolutionary strategy to compensate low natural survival rates. Populations depend on the survival of individuals once they reach

Although with the temperatures rising so steadily normality is not as easy to come by when you are a sea turtle. Especially with temperatures spiking the way that they have been in the last few years in sea turtle’s main nesting areas such as Florida. Florida simply being one of the more common places

Sea turtles are becoming more and more endangered as time goes on and is something that really needs to be changed. There are seven species of sea turtle and they are all either endangered or critically endangered. Millions of sea turtles used to inhabit the sea now only a fraction of them are still around. Humans are partly the cause of this because we hunt them for food and profit. It is unbelievable that people can kill such beautiful creatures just for their personal benefit. Humans are not the only reason sea turtles are facing extinction, but we are the main reason. Humans really should not be part of the problem in the first place.
