Abstract
Sea turtles are a very well known marine species. But not many people really know the true stories behind sea turtles. They are considered a very endangered species in the marine ecosystem therefore the aim of this study is to inform people a more in depth view of sea turtles, including the characteristics of sea turtles. Such as, the different types of sea turtles, their habitats, and their reproductive system. Also a few real life cases that involves stories about sea turtles that are harmed. The results of this study implied that human actions could effect the sea turtles population, as well as other aquatic animals.
Aquatic animals have always been endangered especially due to the pollution in today’s generation. Us humans

Sea turtles are included as one of the many endangered animals in the world, yet not many people are aware of this. Therefore people should be informed about sea turtles characteristics, reproduction system and also learn about past incidents that has harmfully affected the sea turtles. Turtles; they are reptiles of the order Chelonia, also known as Testudines. In general they are mostly recognized especially by the enclosure of the internal body organs in a hard shell. These species can be omnivorous, carnivorous or herbivorous, some species that live in land prefer eating green. All turtles lay eggs, which they bury in holes. They are also long-lived; some species can live for more than 100 years. Taking a more in-depth look of the sea turtles, there are 7 different types of sea turtles, such as the green, loggerhead, hawksbill, Kemp’s ridley, flat back, olive ridley sea turtles that are included in the family Cheloniidae and there are also the leatherback sea turtles, which are the only extant member of the family Dermochelyidae. They live mostly in warm and temperate seas around the world. Different types of sea
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 efforts taking place through different conservation organizations and the State of Florida are making a mixed impact on the survival of Manatees and Sea Turtles. The decline in manatee population has decreased, but due to low reproduction rates, more needs to be done to avoid extinction. The sea turtle outlook is more species specific. Some species of turtle are seeing stabilization in population, while others are not. The State of Florida has a large array of custom license tags that support the conservation efforts taking place within the State. The proceeds go to benefit the local marine life in Florida. With financial resources, state and local cooperation, and through constant research and observation, we are able to learn more about both of these gentle animals. With human awareness of those living in Florida, these two animals will survive
There has been a steep decline in sea otter populations due to water pollution and exploitation of furs. This has adversely affected marine ecology. It is therefore suggested that sea otters should be included in the endangered species list to protect them from further exploitation. This study focuses on the community ecology of sea otters and their impact on marine ecology. The need for their inclusion in the Endangered Species list and the implications of such an intervention are also evaluated.
For years poachers have hunted these animals and slaughtered them in order to obtain there amazing water resistant coats. By the 1900’s there was a treaty signed to protect all of the sea otters, and even after Japan withdrew from the treaty Canada and the United States still kept it in effect. Even after the poaching stopped the pollution continued. Sea otters find themselves submerged in the giant oil spills that the tankers cause. When oil gets into their fur is causes it to no longer be water resistant, therefore most sea otters die because they freeze to death. If they are in the warmer parts of the world, like California then the oil causes death from its toxins when the otters are trying to clean themselves. Oil spills and the garbage in the water are causing tons of marine deaths each year.
...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.
This is a problem because the shark species that are endangered or threatened are unable to repopulate. (Sharkwater) Sharks are culled outside of meat and fin industries for sport fishing which can have a large environmental impact due to the fact that most of the fish hunted for sport are charismatic megafauna. The great white is an example of this phenomena.
When fishers throw their nets, the turtles get caught in the nets causing damages to their body or drowning them. When juvenile loggerheads head to their foraging area in the water, they are highly exposed to bycatching, international longlines, and illegal, unreported and unregulated (IUU) longline fisheries causing high mortality rates (Peckham et al. 2008). Though juveniles have a higher mortality rate due to bycatch, longlines and trade since they are still maturing, adults are easily exposed to these threats as
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.
This is another reason why so many washing up dead on beaches is troubling. The most obvious cause is pollution and plastic that’s dumped into the oceans that the turtles mistake for food. Hopefully, the autopsy of this current dead leatherback turtle will give scientists some
Water pollution has had devastating effects on the environment, which include irreversible effects on the oceans ecosystem. People often underestimate the importance of the ocean. They don’t realize how much damage pollution has caused to the ocean and the thousands of creatures that inhabit it. Earth is a huge place, but resources are actually very limited and will not last forever unless there is a balance. We must protect the resources we have in order for them to last into the next generation.
There are 1,436 endangered species in the United States alone. (2) Every species depends on the survival of another, so what happens if one goes extinct? Every organism is affected in one way or another, and it is definitely not a positive affect. There are various terms to describe the status of these animals, just as there are many factors that played into them reaching that status. The extinction of an organism affects everything that the organism at hand comes into contact with directly and indirectly. That is true everywhere, even in your own backyard. There are also many methods discussed and practiced to counteract the extinction of species, but some are not near as successful as others. Though extinction is natural, it is important that we are not the cause of it, and that we do everything in our power to keep it from occurring.
This topic was chosen because the author has an interest in ocean conservation. Careful consideration of a topic was given as environmental sustainability had to be linked to the topic inquiry. With this in mind, it was decided that research would be conducted on the effects of plastic pollution on sea turtles and the effects this has on their population. Initial research found numerous articles, journals and websites. Environmental issues in marine life can lead to emotional bias responses, especially as the sea turtle injuries and health issues are from plastic pollution that is caused by man.
Some of the species being threatened by pollution include: dolphins, porpoises, penguins, sharks, and polar bears. B. Humans are also being affected. 1. Clean water is needed for good human and animal health, but as DoSomething.org states, over 1 billion people worldwide don’t have a means of getting clean drinking water, an... ... middle of paper ... ...
Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth. However, as important as marine life is, that is not the only reason why saving the oceans is crucial. The ocean floor provides natural resources such as, oil, natural gas, petroleum, minerals, medications, and ingredients for foods and products. The economic benefits of the oceans are huge and significant, as well. Fishing and fish products have provided employment to 38 million people and have generated about $124 billion in economic benefits. However, oceans are on the verge of crisis, marine life, natural resources, transportation, the economy, and important ingredients are at risk due to overfishing, pollution, and acidification. Thus, in this essay I will argue that, oceans are not impervious to human activity and threatening the health of the ocean threatens the health of humanity, since oceans key to our survival.
Did you know that more than 90 percent of all organisms that have ever lived on Earth are extinct? According to Pandey, the author of Humans Pushing Marine Life toward ‘Major Extinction’, nearly 10,000 species go extinct each year, and this rate is estimated to be 1,000 times higher than the natural extinction rate (1). Human beings are causing irreversible damage to the oceans and their wildlife, which is being led by two major reasons: Commercial fishing or over-fishing, which damaged the marine environment and caused a loss in the marine life diversity, and pollution, which is a primary way of the extinction causes that drastically modifies the marine life habitat. As a result of the commercial fishing and pollution, many of the marine species will start disappearing of the oceans. Briggs emphasizes that over-fishing “has induced population collapses in many species. So instead of having less than a hundred species at risk, as was the case some 30-40 years ago, there are now a thousand or more (10).”
