On beaches all over the world, Leatherback sea turtles are born less than 3 inches long but can grow to up to 8 ft.: Swimming through the ocean, as the biggest sea turtle. By definition an ecosystem is all living and nonliving things that live in a specific area. The pelagic zone above the abyssal, is located next to the continental slope or drop off. At the surface there's a lot of light. Down below there is no light and it is cold, the water pressure is higher. Like all animals, the leatherback sea turtle is part of an ecosystem that affects everything about their lives such as their adaptations and the environmental threats they face.
First off, Leather backs ecosystems affect their adaptations, like their special tooth to break out of their eggs their pulmonary sphincter and possessing no teeth. First, A Leatherback sea turtle has the cool adaptations of a caruncle. According to seeturtle.org Leatherbacks break out of an egg using a small short term tooth located on their snout called a caruncle. Because, of the rock hard egg shell this adaptation is necessary it is a small tooth on the front of its face that helps it break out of their eggs. Next, A

To begin, A Leatherback sea turtle faces the environmental threat of pollution. In the text, “Approximately 6.4 million tons of plastic and debris enter the oceans.” This shows that the ocean faces pollution which will get trapped around them and will cause them to die. Next,A Leatherback sea turtle faces the environmental threat of bycatch. In the text fisheries bycatch by seeturtles.org “Incidental capture in fishing gear (also known as bycatch) is likely the greatest threat to sea turtles and many other species worldwide. Approximately 40% of all animals caught in fisheries are discarded as
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,
The poem Mark O’Connor wrote “Turtles Hatching” at a time in his life when was closely studying nature.
...legal fishing, caught in fishing nets, collisions with boats and or propellers, and marine pollution. The subsequent captivity of dolphins in research and aquarium facilities contributes to their deaths.
...rients and balance sea floor sediments. Many environmental and government run programs have been created to help the efforts of saving sea turtles. Some of the actions include making mass fishing companies use safer methods to prevent catching turtles, ordinances that control lighting along beachside properties, and small groups protecting nests from their creation to hatching. In addition to these measures, wire mesh gratings are put over the nests in order to protect them from being scavenged by foxes (Kurz, Straley, Degregorio, 2011). Although these efforts do make a positive impact, loggerhead’s migration patterns are so vast and worldwide that it is almost impossible to truly enforce conservation efforts. This is because sometimes they can be seen as an “inconvenience”. It is important that we strive to protect this important component of the ocean’s ecosystem.
1 The sea otter is endangered because of oil spills in 1977. Tons of otters where hurt and were sent to the Marine Mammal. Under state law, southern sea otters are "fully protected" mammals. Southern Sea Otters are one of the smallest marine animals. Their fur is thick but soft when dry but in cold waters the thickness keeps them warm. The thing they eat are sea urchins, abalone, mussels, clams, crabs, snails and at least 40 other marine species. 2 Sea otters exhibit numerous adaptations which help them survive in their challenging marine environment. Long whiskers help them to detect vibrations in murky waters. Did you know that the sea otter is part of the weasel family and is the second biggest? Mating happens all throughout the year. Sea
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
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)
Evolution is a process of living things change slowly in a very long time, so it evolved into a new species more complete body structure. According to the theory of evolution, living now in contrast to living in the past. The ancestors of creatures alive today may experience changes in form and structure. In addition, may experience changes in both the structure and genetics in a very long time, so the shape was totally different from the original and finally generate different types of species present. So the plants and animals living there now was not the first time here on earth, but it comes from living in the past.
Harmfull Effects of Ocean dumping include animals in danger with trash in their habitat, as well as contamination of public waters.
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.
Many of the methods used in commercial fishing are very destructive to the aquatic systems. Industrial ocean trawlers scrape the bottom of the water, often dragging up the seafloor with them. This destroys the habitat and kills many of the bottom dwelling organisms that are vulnerable to these practices. There is also a large amount of marine animals that are unintentionally caught by the large nets. These animals are considered bycatch, having no value to fishermen and are usually killed. These large fishing vessels also add a significant amount of pollution to the water. Fishing vessels cause oil spills as well as discharging chemical elements and wastes into the water. The thousands of of trawlers that pass through Japanese waters create large quantities of water pollution that can devastate aquatic life by changing the chemical composition of the water and affecting all the organisms that inhabit these
sea otters are from the kingdom animalia. Sea otters are stouter and have large rib cages, smaller tails and muzzle than other species of otters. Yet sea otters posses the fine, dense fur coats characteristic of the Mustelidae. Their forefeet are small and dexterous with retractile claws and the flipper like hind feet are broad and webbed. Sea otters once was abundant along most coastal North pacific ocean. That was before fur traders hunted them for their thick ice, luxurious pelts. By the year 1900, sea otters were nearly extinct . Protected since 1911, alaska sea otters have made a comeback. There lifespan is 10-15 years. Great white sharks are the primary predator of sea otters and occasionally eaten by coyote so the predators that the
Some of the species being threatened by pollution include: dolphins, porpoises, penguins, sharks, and polar bears.
