When a species is threatened by extinction it falls under the category of being an “endangered species.” Each species has different threats which affect their survival rate. Many species may be affected by loss of habitat or loss of genetic variation (Society). However, other reasons exist and are prominent as well such as egg collection and unintentional capture when operating fishing equipment. There is class of sea turtle that is the rarest species of sea turtle, the smallest species of sea turtle, and the most critically endangered sea turtle in the world (Fisheries).
The Kemp Ridley Sea Turtle has an average lifespan of 50 years, weighs 100 pounds and is 2 ft. in size (National Geographic). It usually resides in the coastal waters and bays of the Atlantic Ocean and the Gulf of Mexico. A prevalent threat to survival it happenstances is over-harvesting of

People harvested the eggs in truckload sizes throughout 1940’s and 1960’s and sold them in little towns in Texas and Mexico (Texas Parks & Wildlife). The Kemp Ridley’s Sea turtle was put on the “Endangered Species Conservation Act of 1970” on December 2, 1970 (Fisheries). This has become a massive setback, it initiated their nesting activity to be called “arribadas” (National Geographic). When a “arribada” occurs, all female sea turtles take over the seashore in pursuit of the perfect space to place her offspring. A female Kemp Ridley Sea Turtle is sexually mature once it is 10 - 12 years old which means reproduction rates are low as many females don’t survive to this maturity level. With that being said, the nesting grounds are now being safeguarded. The
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
“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
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.

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 turtles are becoming endangered more and more often. Not many people understand the dangers that these turtles are in, especially when the females are nesting. Nesting takes an important role in the lives of these turtles and is an amazing process that occurs during the season. Unfortunately, many factors disturb the process of these hatching eggs. This paper explains these factors in depth to educate the audience about the dangers involved in loggerhead nesting. Light pollution, natural disasters, and predators are described and explained as to why they affect the process of nesting. Many organizations are trying to share their knowledge on these loggerhead-nesting dangers with people and are trying to help keep the loggerheads alive.
The Blanding’s turtle is identified by its unique appearance. Its top shell is a round, dome shape unlike other turtle species. The top shell is black with characteristic yellow or tan spots, and the under shell is a light yellow with characteristic brown spots. The neck and throat are a bright yellow, making it easy to identify from other turtles species. Adult males can reach lengths of 11 inches, and females can reach lengths of 8.5 inches. They are relatively medium-sized, and often nicknamed the “semi-box” turtle because they are physically similar to the box turtle.
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
Imagine a world where sea turtles are extinct; did you know that was preventable? The hawksbill sea turtle population is drastically low and if action is not taken they will soon become extinct. Several factors come into play in the extinction of this species; the most evident one is their breeding behavior. Due to the natural breeding behavior of the hawksbill sea turtle and their inability to sustain a viable population, they are going extinct; however, if they were introduced into breeding programs their extinction would be prevented.
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.
Sea Turtles and Evolution Human activity is endangering a vast array of lifeforms that have inhabited the Earth for millions of years. Recently I visited the Field Museum in Chicago Illinois to tour an exhibit titled The Evolving Planet. The story that the exhibit told was that of life on planet Earth, and how throughout time Earth has reinvented itself using whatever surviving species that remained after its latest mass extinction period had ended. It depicted in a graphic format how time and catastrophes have forever changed Earth’s landscape, including its inhabitants. One of the inhabitants that has managed to survive and evolve is the sea turtle.
In the world today, there are about five thousand endangered species. Around one species dies 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.
