Sea Turtle Protection
Sea turtles are related to the land turtles but have special adaptations like flippers to help them move under water. However, they still have to come  on land to lay their eggs. There used to be at least 27 species of sea turtle of which 19 were extinct a very long time ago. Fossil analysis show that they date back to the Jurassic period. Since these turtles were highly specialized, they did not adapt well to environmental changes, which is believed to be one of the causes for their extinction. Seven of the eight remaining species are currently listed as threatened, endangered and critically endangered like the leatherback turtle (Dermochelys coriacea) and the Kemp's Ridley (Lepidochelys kempii) due to direct and indirect human impact, while one species is actually extinct.
The logger head turtles (Caretta caretta) were listed as vulnerable in 1992 and are currently listed as threatened. These turtles are directly impacted by human stressors like disturbing nesting sites by poachers and onlookers, ocean debris, and pollution,  but the biggest culprit is massive accidental catches during their long migrations.

Better management of the animals and their habitat is needed to protect them from extinction. One way to help them is by limiting direct access to nesting grounds, creating national parks, as well as protecting their foraging and mating areas, since turtles return to the same sites year after year. Some protection measures  to save these animals are being implemented, but a lot more effort is needed to guarantee their survival.
