Recommended: Sea turtles impact on the environment
When people walk along the beach, you may cross upon a bunch of creatures that is trying to crawl toward the vast ocean. These creatures are sea turtles. Sea turtles are large marine reptiles that are cold-blooded vertebrates and have leathery or bony flippers and shell (Lutz and Musick, 1996). They are aquatic reptilian creatures that has wide spectrum of coloration ranges between yellow, greenish, and black depending on the type of sea turtles. They are from the kingdom of Animalia, class of Reptilia (Matthews, 1990). The earliest known sea turtles appear in the fossil record in the Late Jurassic period, 208 to 144 million years ago. Scientists believe that modern sea turtles are derived from marsh-inhabiting ancestors that lived during the Late Triassic period (seaworld.org, 2001). Therefore, for millions of years, sea turtles were around since the dinosaur age, and that today they still exist and can be found in the world, which makes sea turtles one of the Earth’s ancient species. They can be found in all warm and temperate water throughout the world. Their habitats are located in the bay, shallow, coastal waters, lagoons, and open sea (Lutz and Musick, 1996). However most sea turtles undergo a long migration between their feeding grounds and the beach where they nest. Unlike other turtles, sea turtles cannot retract their head or legs back in the shells. Depending on the sea turtles, they can be carnivorous, herbivorous, or omnivorous. Sea turtles feed on shrimps, jellyfish, sponges, and vegetation. There are total of seven species of sea turtles: leatherback sea turtles (Dermochelys coriacea), green sea turtles (Chelonia mydas), hawksbill sea turtles (Ertmochelys imbricate), flatback sea turtles (Caretta caretta), Kemp’s... ... middle of paper ... ...misingly. Sea turtles can still be an existence and furthermore their population can continue to rise. Sea turtles are still listed as endangered species. In the ecosystem, all species have an important role. Sea turtles have their role in the marine ecosystem. They are the representative of a group of reptiles that exist since back of time. They are the essential of the wildlife. Without sea turtles other animals that feed on sea turtles will not have food source and they will disappear. It destroy the balance of the marine ecosystem and with problems that is still happening, the sea turtles are endangered. For future, sea turtles will be off the list of being endangered and their population will rise up. In hopes of sea turtles be able to still be remaining in the ecosystem and eventually the production of more sea turtles will be a better turn out for the world.
In the Grapes of Wrath, a novel by John Steinbeck, there are many examples of symbolism. One of the most prominent symbols found in this book is the turtle seen in chapter three. This turtle is symbolic of three things: the Joads and their journey west, Tom Joad himself, and the promise of new life. First, here’s a little background information on the turtle. This land turtle was somewhere to go. Where than is, no one knows, except perhaps John Steinbeck. To get there the turtle decides to take the perilous journey down a dusty dirt road that stretches along the quiet countryside. What could happen? A lot more than one might think. In fact, the turtle faces quite a few challenged ranging from pesky insects, to ledges, to even cars. But, the thing that makes this turtle special is that he never gives up (Pages
Throughout the animal kingdom, adaptations take place continuously and even the smallest of changes can leave a significant impact. Examples can be seen within any plant or animal. One example would include sea turtles, specifically, the Loggerhead Turtles. These turtles are native to the Indian, Atlantic, and Pacific Oceans as well as the Mediterranean Sea (Deurmit L 2007). They thrive in either temperate or tropical climates and can live in a myriad of biomes (Deurmit L 2007). These biomes include the pelagic, reef, coastal, and brackish water (Deurmit L 2007). Loggerhead turtles are omnivores and can eat anything from insects to aquatic crustaceans, to macro algae (Deurmit L 2007). According to Deurmit (2007) Caretta caretta is classified into Animalia Kingdom, Chordata Phylum, Vertebrata Subphylum, Reptilian Class, Testudines’ Order,
Being around for 45 million years is not enough for the Florida Manatee to continue to survive. The Florida Manatee is in danger of extinction. Surveying obstacles have prevented getting an exact population count; until the end of 2009 the best estimate was somewhere between 1,000 and 3,500 manatees left in the wild. This number was considered fairly accurate until January 2010 when a 2-week cold snap in Florida pushed the preliminary Florida Wildlife Service ae...
During the 18th and 19th centuries, sea otters were hunted for their luxurious pelts, and by the early 1900s, the species was believed to be extinct in California. (Carswell) Why do we care you ask, well not only are they super cute and eat with their hands. Apparently, a healthy population of sea otters keeps the sea urchin population in check. An unhealthy or small population of sea otters allows the sea urchin’s number to explode thus decimating kelp beds, which is the sea urchin’s food source, and causing a “chain reaction that depletes the food supply for other marine animals consequently causing their decline. (Kuipers)
The green sea turtles have been taken out of the Atlantic Ocean for several years, so now they are an endangered species. Today, the green sea turtles population is growing and in the Florida Refuge they counted up to over 12,000 turtle nests. It is shocking to see how much the refuges care about the green sea turtles. They have been looking out for the turtles for 35 years. It was interesting to find out that these green sea turtles live for a really long time. It takes the turtles 25 years just to mature. This article caught my eye because I love science and animals. Knowing that people are taking care of what used to be endangered animals really means a lot to me. I hate seeing animals hurt or struggling to survive. Because of the refuges
Loggerhead sea turtles, scientifically labeled Carretta carretta, are the most global nesting turtle species and the most abundant in United State’s waters. While they are not nesting, they travel through open ocean water, spending time searching for food and resting on the sea floor. These turtles were nicknamed Loggerheads because of their large heads and strong jaw needed to break the shells of crustaceans. Loggerheads have the largest nesting range of any sea turtle, inhabiting the Atlantic, Indian, and Pacific oceans (Spotila, 2004).
...and food. Their skin is used to make high quality leather. In 1950, American alligators were seriously endangered because humans were over hunting alligators. Then in 1967, the endangered species preservation act stopped the hunting of alligators and the number of alligators quickly rose. Now there are millions of alligators and people are allowed to hunt alligators again. Alligators are losing their habitat because wetlands are being filled to create land for houses, farms, and industries.
The Florida Manatee’s popular marine species in the tropical environment of Florida are currently considered an “endangered species”. The ecology (the relationships between living organisms and their interactions with their natural or developed environment), for the manatee (trichechus manatus), requires and is generally restricted to the inland and coastal waters of peninsular Florida during the winter, when they shelter in and/or near warm-water springs, heated industrial effluents, and other warm water sites (as stated in Research Gate (1997) Hartman 1979, Lefebvre et al). The Florida (West Indian) Manatee, An Endangered Species, has no known predators other than humans; in the past, humans hunted
They affect it by maintaining balance in the sea’s food chain. Leatherback turtles rely on huge quantities of jellyfish for nutrients, they are known to eat almost 200 kg of jellyfish per day. Without these turtles the world’s seas would be abound with jellyfish and, since jellyfish feed on fish eggs, this would further hasten the decline of worldwide fish population. (OCEANA, costaricaturtles) However, the Pacific population of leatherback turtles have declined with 90% the last two decades, due to commercial fishing. (seeturtles)
Loggerhead Sea Turtles have many important benefits and attributions not only to the ocean but to humans as well. Since Loggerheads transport nutrients from oceans to beaches through their migrations and nesting they increase the rate of nutrient recycling in benthic, ocean bottom, ecosystems (Wilson et al. 2010). They constantly will be maintaining the coral reef ecosystem as well.
These basking rocks, or even floating cork for younger turtles, are very important, they have to have a place to bask and get out of the water. Yet if you decide to keep it outside be sure to provide a place to bask, plenty of water, filters, and a covering so other predators can not harm or eat your turtle. Equipment will be different for indoors or outdoors. If you keep your turtle indoors be sure that it can occasionally get fresh air and sun light, but do not keep an aquarium next to a window! Also, make sure your aquarium or pond is clean, this is extremely important to maintain good health for the turtle and provides them with a clean habitat.

Any species which fall into the categories vulnerable, endangered, or critically endangered are considered to be at risk of extinction. Robert Redford said “I think the environment should be put in the category of our national security defense of our resource’s because it’s just as important as defense abroad otherwise what is there to defend?” People should all take the environment more seriously and protect the future for those to come. It’s our responsibility to ensure that the children to come may enjoy all of earth’s beauty, and not through old issues of National Geographic’s.
In the world today there are about five thousand endangered species. Around one specie dies out every year. Some animals become endangered because people are killing them for their horns, as in the case of the Black Rhino of Africa. Others become extinct because pesticides are put on the food we eat, causing the animals that eat the insects off the plant to become contaminated, which causes their predators to become contaminated, which often affects the shell of that organism?s egg. Here is a list of the endangered species, 91 endangered birds, 76 endangered mammals, 36 endangered reptiles, 21 endangered amphibians, 115 endangered fish, 70 endangered clams, 35 endangered snails, 44 endangered insects, 12 endangered arachnids, 21 endangered crustaceans, 594 endangered flowering plants.
In our world today we have approximately 26,021 endangered species. Endangered species are organisms that may possible become extinct. The term 'endangered species' refers to all species that fits this description. However some conservation biologists and scientists normally use the term ‘endangered species’ to refer to species that are put on the IUCN(International Union for Conservation of Nature)Red List. Many factors can be looked at when considering the conservation status of a species. Factors such as human threats or environmental threats can cause a species to become endangered.
