Preserving Sea Turtles in United States Essay

Now, as most may know sea turtles are both marine and land animals depending on what stage of life they are in. Which means that they need to be able to go on land during certain stages of their lives. One of the main reasons why a sea turtle will go on to land is to lay their eggs. Within the last few years this has become harder and harder for the already endangered species. It

Turtles are one of the oldest reptile groups. They are classified as amniotes. They have existed a long time ago, which means they have seen the rise and fall of the dinosaurs and the rise of humanity. Scientists think that turtles have existed for around 157 million years (mosaic 29). Approximately, sea turtles were 65 million years ago (Dobbs 1). This family has survived the passage of time and is threatened by the contamination that humans have created in the ocean. The six sea turtles that occur on the coasts of America are in fact threatened. Sea turtles are very important for the ecosystem, but humans, directly and indirectly, endanger this family. If humans do not stop their destructive habits, we can lose the influence of sea turtles on seafarers. Sea turtles play an important role in the ecology of the ocean, and without turtles, we can see an ecological collapse in the oceans. Sea turtles are one of the few animals in the sea that eat sea grass (Godfrey). Sea turtles act as grazing animals that cut short grass and help maintain the health of the family of seaweed (Godfrey). In recent decades, there has been a decline in the sea grass family. This decrease may be related to the decrease in the number of sea turtles (Godfrey). Sea grass is important because it is a fertile ground for many species of fish, shellfish and crustaceans (Godfrey). The beaches and sand dunes are known for not having many nutrients. When the sea turtles reach

The leatherback sea turtle, Dermochelys coriacea, belong in the phylum of Chordate, class of reptilian, order of Testudines, and the family of Dermochelyidae. These reptiles can be found throughout the Pacific, Atlantic, and Indian Oceans. Leatherback sea turtles are the largest turtles in the world. The average life expectancy of a leatherback turtle is forty-five years. Average size of the turtles upper shell, carapace, is about five feet and has a rubber-like texture feel to it consisting mainly of oil-saturated connective tissue. On average Dermochelys coriacea can weigh any where from approximately six hundred to two thousand pounds. In length these turtles are typically fifty-five to seventy-nine inches. The lack of claws is another distinguishing

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

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.

This rare turtle found in the United States is the smallest species of turtle in the United States. It can only grow up to 4.5 inches long! This tiny turtle is in two very small distinct populations that are approximately 250 miles away from each other. These turtles are very recognizable by the orange patches on their head. The National Fish and Wildlife foundation says, “In the last 30 years, these turtles have disappeared from more than 50 percent of the wetlands it once inhabited.” I believe we should be resurrecting more of the land that they used to live on.

Loggerhead eggs and hatchlings are a large food source for a variety of terrestrial animals, nearshore predatory fish, and seabirds, providing substantial amounts of energy and nutrients for these species (Wilson et al. 2010). A five or ten year period of loggerhead turtle declines may cause sublethal effects such as decreased growth rates or reproductive output for these predator species and a fifty year period of loggerhead turtle decline may potentially have more severe impacts such as significant declines for local populations that rely on eggs and hatchlings as a food source.

The Chelonia mydas also known as the green turtle is currently classified as an endangered species and is one of the oldest living marine vertebrates. The aim of this paper is to examine the Chelonia mydas the chain of events that has caused the decline of its population primarily through human activity, diet, and relationship to its ecosystem. The paper will conclude with a discussion of current conservation efforts implemented to save the Chelonia mydas population. Such efforts include restrictions on human hunting and Identification of marine areas for conservation via satellite tracking.

The Graptemys caglei, also known as the Cagle’s Map Turtle, is an endangered turtle species found in San Antonio, Texas and along the Guadalupe River. It identifies easily by the pattern on its shell which resembles an aerial view topography, as well as its spiked shell edges, which are not as sharp as other map turtles of the same genus. Although the Cagle’s Map Turtle has natural predators pose a threat to the individual turtles’ lives, the predators are not a greater threat than habitat disturbances created by humans. Unfortunately, this species suffered a significant drop in population since the mid-1970 through changes in its habitat disallow support of a larger population of the turtles(van Dijk, P. P., 2011).

In Australia, loggerhead turtles nest on open sandy beaches (Environment, 2001). Therefore when hatchlings are born they need to make their way down to the ocean, this makes them vulnerable (Environment, 2001). Baby turtles and most vulnerable when they are scurrying, to the water because there are many obstacles along the way (Nobs, 2004). For example baby turtles mistake artificial lights for the sea and are then more likely to be killed by predators such as birds, raccoons, foxes and cats, which are just a few of the predators these vulnerable creatures face (Marine Bio, 2015). Around 10% of hatchlings from each batch are lost artificial lights each year. To decrease the amount of baby turtles killed we are going to fix how far the artificial lights are between each other. When breeding season takes place there needs to be a rule that four lights every kilometre need to be turned off. This will help by reducing the amount of hatchlings that take a wrong turn towards the light, and attract unwanted predators. This problem could most probably be bought with an organisation called ‘Sand Cloud’. When you purchase one of Sand Cloud’s products, you help to preserve and protect oceans, and Marine Life. 10% of their net profits are donated to saving marine life. In particular turtles. So if this problem was bought up with them they would probably take it up and solve

The Ocean is 70 percent of the earth’s surface, humans have explored less than five percent of the ocean, and is home to an innumerable amount of living organisms. One of its oldest inhabitants is the Cheloniidae dates back to the Triassic era, roughly 250 million years ago, (Wang et al., 2013). The Cheloniidae family has several subspecies the Eretmochelys imbricate, Caretta caretta, Dermochelys coriacea, Lepidochelys olivacea, and Chelonia mydas. While there are multiple endangered subspecies of the Cheloniidae; the endangered Chelonia mydas, commonly known as the green turtle, will be the focus of this paper. The paper will discuss the green turtle’s importance to its ecosystem, where they are most commonly found, importance to its ecosystem,

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 Blanding turtle are freshwater medium sized turtle usually found in The Great Lakes Regions in USA and in Canada. They are from the omnivorous species and usually eat crayfish, small animals, and plants. Their life histories traits occurs between April and November, as May and April tend to be more for mating and Early June for nesting. Less than half of these females will actually go on to reproducing. Many of these turtles can actually live up to sixty to a hundred years in age. Though these turtles spend a majority of time in the aquatics they also come on to the mainland. This is were the problem starts to occur and this is why the Blanding sea turtles are currently threatened and may soon be extinct. It is because of us humans that these species are currently facing habitat loss, have threatened nesting areas, and are unable to get from nesting areas to the lakes because of manmade roads. Why should we as humans care so much if these Blanding’s turtles go extinct? These turtles play an important

Sea turtle hatchlings are now having trouble finding their way to the sea because of all the lights from buildings that are built on the coast. They get disoriented when they are born and will wander in the wrong way away from the sea. This leads them to predators that live inland or will even cause the turtle to become dehydrated and die. Humans are also building coastal armoring that is blocking female turtles from reaching a suitable nesting habitat. This is a severe problem in Florida where they have many coastal rock elevations and sand bags. Where all this beach development is occurring thousands of sea turtles are trying to nest. Beach dredging is also having a direct effect on sea turtle's trying to nest. If the sand is too impacted or is drastically different from native beach sediment, the mother will have trouble creating the

Sea turtles have been a big help in maintaining the health of the world's ocean for more than 100 million years. They help by keeping up coral reefs all the way to transporting nutrients to beaches. Major changes have occurred in oceans everywhere due to the decline of the sea turtle population. Oceans are unhealthy because of this. It is time for us to protect the sea turtles and rebuild their population to ensure healthy oceans in the future. According to oceana.org, there are seven species of sea turtles that roam the world, six of which inhabit U.S. waters, and have been listed as either endangered, or threatened. Up until now, all six of these species are not at a healthy level despite protection measures from the Endangered Species Act (ESA). Some populations even continue to decline. Even at a diminished population, sea turtles play an important role in ecosystems. They are also extremely important to humans because they keep oceans healthy, and we use the ocean as a food source. They keep up the health of the ocean in many different ways, all of which, are very important.
