Turtles have been around for about 230 million years (Dobbs 1). In that time, they have seen the rise and fall of the dinosaurs and the rise of mankind. Marine turtles have been around for about 65 million years (Dobbs 1). This family has withstood the test of time and is being threatened by human’s impact on the sea. All six of the marine turtles occurring on the shores of America are at least threatened. Marine turtles are very important to the ecosystem but humans are endangering this family directly and indirectly; if humans do not stop their destructive habits, we may lose the influence of marine turtles on the earth’s seas.
Marine turtles play an important role in the ocean's ecology and without turtles we may see an ecological collapse in the oceans. The marine turtles are one of the few animals in the sea that eat sea grass (Godfrey). Marine turtles act as grazing animals that cut the grass short and help maintain the health of the sea grass beds (Godfrey). Over the past decades, there has been a decline in sea grass beds. This decline may be linked to the lower numbers of Marine turtles (Godfrey). Sea grass is important because it is a breeding ground for many species of fish, shellfish, and crustaceans (Godfrey). Beaches and sand dunes are known to not have alot of nutrients. When Marine turtles come to land they well bury their eggs in the sand of the beaches. Not every nest will hatch, not every egg in a nest will hatch, and not all of the hatchlings in a nest will make it out of the nest (Godfrey). All the dead hatchlings make a good source of nutrients for the beaches; the shells of the hatchlings make a good source as well (Godfrey). If marine turtles were to go extinct, then the beaches and sand dunes will lose a...

In the nineteenth century, the Florida manatee population started to decline in numbers due to settlers hunting them for their meat (Pittman 15). In addition, during that time some of the scientists started to notice a decline in manatee sightings in areas they were known to migrate. Since permits were being granted to kill Florida manatees for science, and poachers were hunting them for their meat, government officials and researchers were concerned for the manatee's future (Pittman 17). Currently, there are many factors the Florida manatee is facing that poses a threat to their existence. Unfortunately, the greatest threat to the Florida manatee in the twenty-first century is boating and the loss of their natural habitat (McAullife 18). In fact, many boaters who have businesses have protested that their businesses are more important than the clumsy animals. Currently, another public concern for the Florida manatee is the increase of toxic blooms that cause red tide. In addition, since records have been kept researchers have discovered that red tide has been playing a role in the decline of the Florida manatee as well (Raloff 56). Red tide is a form of many toxins that are consumed by the manatee when they feed on seagrasses causing lung
The Sea Shepherds are group of volunteers who try to protect the sea animals, and capture criminals who kill the animals without permits. Their website has many purposes, one dedicate to collect donations from the reader. Furthermore, they want to protect the ocean wildlife. The website audience includes people who want to protect the ocean, and they want to save the sea animals which will likely be extinct. They offer the audience a chance to donate, volunteer, and stay up to date with ongoing issues involving marine life. This website is outstanding because the sea shepherds host a successful website that effectively reaches out to the audience through appealing to the reader's emotions, logic, and credibility.
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
The manatee has been on the endangered species list since the year. 2001. The 'Secondary' of the 'Secondary' This is caused by pollution in the water, power boats, and slow reproductivity. The symbiosis of the symbiosis. As a result, humans are putting an effort into saving these seas.
“On Broadway, in New York, there is a penny arcade which used to sell baby terrapins that were scrawled with bon mots in enamel paint, such as KISS ME BABY.”(Hoagland p.154) “They were as dry as a heap of old bones in the sun; nevertheless, they were creeping over one another gimpy, doing their best to escape.” (Hoagland p.154) “He drank thirstily but would not eat and had none of the hearty, accepting qualities of wood turtles.” (Hoagland p.155) “He was morose, paler in color, sleeker and more Oriental in the carved ridges and rings that formed his shell.” (Hoagland p.155) Take a gander at how a turtle begins its life. In the wake of deliver, generally to some degree close to the water, it gives off an impression of being adequately fundamental to twist over some sensible sand and start swimming off to begin a presence. Then again, young turtles are in convincing hazard from the most punctual beginning stage. In fact, even with a short detachment to cross and couple of impediments in the course, there are various predators and unforgiving parts to drive forward. A little rate of sea turtles makes it past most punctual stages. An obviously fundamental task has significantly more behind it. Strength isn't for the most part anticipated that would go into something. Every so often it is relied upon to persevere
This article discusses how important the organisms symbiotic with coral reefs are, as well as how important coral reefs are to our environment. Also explained is how natural and non natural things things like hurricanes and overfishing affects them. A study is quoted about how water acidity also plays a role in the bleaching of corals. Lastly, restoration and conservation efforts are discussed and how we could possibly help our oceans.
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).
Manatees, also known a sea mermaids or cows, are on the brink of extinction with funding and environmental protection required to save these amazing animals. Humans are the biggest threat to their existence. Humans have carelessly injured and killed thousands of manatees by slicing and dicing them with boat propellers, all in the name of entertainment. Other negative factors include pollution, environmental reduction due to human encroachment, and poaching with manatees consumed as food. The existence of red tides is another factor posing a natural threat. While manatees may be viewed as large animals in the way of boaters with no real purpose, manatees serve a major purpose by eating vegetation and weeds that cause damage to underwater pipe systems in larger cities. Without them, the removal of this vegetation comes at a huge cost. The existence of one of the most gentle mammals in the world is being threatened. Action needs to be taken now to prevent brutal injuries or death by boat propellers, habitat loss, poaching, and other careless actions that threaten the manatee population.
Horwath conducted many subtidal surveys on SCUBA in southern California and handled marine fish and invertebrates while assisting with research programs while an undergraduate student at University of California Santa Barbara (UCSB). She worked with the Lenihan Lab in UCSB’s Bren School for Environmental Science and Management; with Dr. Jack Engle for the Multi-agency Rocky Intertidal Network, a long-term monitoring program on the West coast of the U.S. with over 90 monitoring sites, and for the Channel Islands Research Program, a long-term subtidal expedition program that includes sites at all eight Channel Islands; and with Reef Check California as a survey coordinator/leader. 2005-2009. Reptiles & Amphibians Role – Piru Creek Diversion Sediment Maintenance Project Biological Monitoring – Location Ms. Horwath surveyed the project area for sensitive species. She monitored sediment excavation activities within the diversion pond for southern western pond turtles, two-striped garter snake, and southern California steelhead.
Introduction Caretta caretta, otherwise known as the Loggerhead Sea Turtle, is an oceanic turtle that exist throughout the globe. They are circumtropical species (LeBlanc et al. 2014) meaning they are distributed throughout temperate and tropical ocean regions, but most abundant species are found in the United States coastal range. Loggerheads largest nesting aggregations in the Atlantic are found along the southeastern United States coastal range where about 80% of all nesting occurs and 90% of all hatchlings are produced (Abecassis et al. 2013).
Leatherback, hawksbill, and loggerhead are sea turtles which are any of two families Cheloniidae and Dermochelyidae defined by feet modified into paddles for swimming. Sea turtles, as the name implies, live in the sea; however, they swim to land to lay there eggs. When an egg hatches the baby turtle waddles across the sand to the sea where it will spend almost all of its life.
Fresh Water turtles are small, yet amazing creatures to have and care for in your home. River Cooters, Red Eared Sliders, and Painted turtles are all common pet’s found in America. Though turtles are fun to have around they do require special care just like any other pet would. In most cases they make great pets but turtles aren’t the easiest pets to have so depending on your lifestyle you should think about how much time you’re willing to put into a turtle. They are usually cheap to buy yet the equipment for your turtle can get expensive. Along with cost you must find the time to put into this pet. They need nice set ups to live in as well as attention and proper handling.
Seagrass is not just a food source for micro species, but also macro species such as manatees, turtles, dolphins and dugongs (Yamada and Kumagai 2012). These marine organisms are all supported directly and indirectly by seagrasses, with some entirely dependent on it. Seagrass is often underestimated in its significance as the vast role that it plays in the oceans ecosystem is not fully understood. ...
