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 proxies of abundance. The result revealed that 5 of 6 subpopulations show a positive trend (North West Atlantic, Mediterranian, South West Atlantic, South West Indian, and North Pasific) and only one (North West Indian) show opposite trend. However, since North West Indian subpopulation is the second largest nesting population and contributes to a third global population, thus altogether, global population
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).
CHARLESTON, South Carolina (Achieve3000, August 7, 2015). A rare leatherback sea turtle was found on a South Carolina beach in March 2015. The enormous reptile weighed 476 pounds (216 kilograms). It was spotted on the Yawkey-South Island Reserve in Georgetown County. The creature was brought to the South Carolina Aquarium. Workers named her Yawkey. She was treated with fluids, antibiotics, and vitamins. She was the first leatherback to be found alive in South Carolina. Caretakers were eager to see her returned to the sea.
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 Hawksbill Sea Turtle is one of the many sea turtles that are going extinct. People may never know when these cute, big sea turtles will be seen again. The Hawksbill Sea Turtles are one of the many unique animals that should not go away forever and only to be seen in a picture book instead of real life.
The main purpose of this study is to provide more information about the Flat-back turtle’s primary route to the conservation team so that they can further enhance their ongoing methods. Along with this, the researchers are also trying to identify the most highly used areas outside the current Reserve Network. Flat-back turtles come under the category of ‘vulnerable’ species; hence it is important to look into their accidental death rate. Protective measures are applied as long as these turtles lay within the Reserve Network; therefore, threats of mortality in the unguarded waters outside the Reserve can be high due to fishery bycatch or collisions with
A sea turtle is a large marine reptile with a bony or leathery shell and flippers, coming ashore annually on sandy beaches to lay eggs. They are very ancient animals. The seven sea turtles you find today have been around 110 years. The types of sea turtles are Green sea turtle, Leatherback sea turtle, Loggerhead sea turtle, Hawksbill sea turtle, Kemp Ridley sea turtle, and Olive Ridley sea turtle. The scientific superfamily classification for sea turtles is Chelonioidea. The scientific name for the Green sea turtle is Chelonia mydas. The scientific name for the Leatherback sea turtle is Dermochelys coriacea. The scientific name for the Loggerhead sea turtle is Caretta caretta. The scientific name for the Hawksbill sea turtle is Eretmochelys
Observing the decline in Blanding’s Turtle populations, researchers have tried to better understand the factors threatening the species, through investigating its reproductive ability and migration patterns. According to a recent study focused on sexual maturity of Blanding’s Turtle, low reproductive rate and delayed sexual maturity of the long-lived organism severely constraints its population to respond to chronic disturbances.
The docile sea turtle population is comprised of several species. They are a species that is in continuous peril from the sandy beaches to the open waters. The dangers imposed on the sea turtle range from nature’s predators to the human impacts on the ecosystem. The sea turtle has been around for millions of years and have managed to survive nature’s predators. However, the sea turtles are struggling to survive the human impact over the last several centuries. Studies have shown the unique lifecycle of the sea turtle and their contributions to the oceans ecosystem. The variety of species throughout the globe contribute in one way or another. However, because of their docile nature, unique swimming abilities, and reproduction cycle,
The endangered animals I’m doing is the Green Sea Turtle. The Green Sea Turtle is a reptile. It diet is herbivore. The Green Sea Turtles habitat varies. Their arms are long like flippers. They were made to be able to go out to the water quickly. Green sea turtles swim about 0.9-0.14mph. Their neck and limbs are non-retractable. They are really good divers.
The Leatherback sea turtle being in the family of Dermochelyidae is a very unique type of sea turtle out of the “7-8 species” that there are (Foster). “Leatherback Sea Turtles are the largest of the species of sea turtles alive today. They are found in oceans all around the world and are known to travel large distances throughout their lives” ("Leatherback Sea Turtle Facts For Kids, With Pictures & Video." Active Wild).
Status: The hawksbill sea turtle is critically endangered from people around the world taking the “tortoise
The invasion of alien species usually has a great impact on the endemic fauna, and the introduction of the red-eared slider turtle wouldn’t be different. This impact can be a result of competition for food or habitat, or simply
Overfishing and nutrient pollution of the seas have brought increasing blooms of jellyfish. “These blooms cause tourist beaches to close, clog cooling intakes at power plants, and burst our trawl nets, but leatherbacks are loving it.” (Our Sea Turtles) A leatherback concentrates in eating jellies, including the nastier stinging ones. It is unbelievable how this unintended environmental increase has influenced leatherback numbers. When most of the loggerheads migrated into the Chesapeake Bay, it was because the food was disappearing and they feasted on the bay’s plenty of horseshoe crabs. “Then, this primitive arthropod with no food appeal to humans suddenly became commercially valuable as bait for eel and whelk traps.” (Our Sea Turtles) As the produce of horseshoe increased, their abundance declined, and loggerhead left with more desperate to catch blue crabs. Loggerhead was enforced with another diet change when over-harvest in the Chesapeake blue crab fishery condensed this prey item as well. Loggerhead in the bay became relying on the scavenging for fish bycatch or “the dead remnants of fish discarded by net fishers.” (Our Sea Turtles) “One of the biggest ecological challenges to sea turtles in a changing world is where to nest.” (Our Sea Turtles) Most of the seas are rising, and the sea turtle’s nests will go away. The
People should protect sea turtles as much as they can. It is always good to know about the animals around you and sea turtles are one of them, especially if you live by an ocean. Sea turtles have been around for over 65 million years and you can’t stop protecting them now.. It is important that humans respect the sea turtles and let them be as long as they are doing no harm to you or your family. Sea turtles are a big part of the marine ecosystem, they eat the seagrass, control sponge distribution, and also feast on jellyfish. Without sea turtles, these things wouldn’t be happening in the oceans around you. So if you happen to see a sea turtle, leave it be as it will make its way back to the ocean with its family.
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.
