Sea turtles

Sea turtles have their habitats in all the world's oceans except the Arctic ocean. At this moment there is seven types of sea turtles in the world of which six is being listed as endangered species. Sea turtles are been on the Earth since Mesozoic but many of them are threatened with extinction all because of us humans.

Not only sea turtles are amazingly beautiful but they're also very advanced creatures with extraordinary sense for time and location and Earth's magnetic field is their navigational system.
It takes them 30 years to mature and only then adult female sea turtles return to the land to nest. Depending on turtle species female sea turtle can nest between 150-200 eggs and incubation lasts about two months. Only about 0,01 % of this eggs has a real chance to become a grown turtle one day because of many predators that lurk around.

Sea turtles are hunted almost everywhere on the world map, despite the fact that their hunting is illegal in many countries as they become food in fancy restaurants. Even in ancient times sea turtles were famous as exotic delicacies (China). But meat isn't the only hunting reason as their shell is traditional decorative ornamental material used in Japan and China.

Six out of seven sea turtles species are listed as either threatened or endangered species.

What people lack is the knowledge of these creatures significance in ecosystem and not only in oceans but on the beaches as well. If these wonderful creatures were to become extinct it could mean tremendous negative impact on oceans and beaches. Two species are already critically endangered Kemp's Ridley and Hawksbill turtles , and other species like Olive Ridley, and Green turtles aren't very far from them.

Their importance is just as vital in oceans as it is on beaches since turtles eat sea grass in ocean and sea grass must be kept short to remain healthy, and beds of healthy sea grass are essential breeding and development areas for many species of fish and other marine life and in beaches they contribute nutrients to beach (as well as dune, which is similar) vegetation from their eggs.

Many countries realized significance of these wonderful creatures and are working on laws and methods which would mean their survival. Sea turtle conservation started in 1970's and 1980's but it didn't resulted as expected since many turtles still make their way in turtle soups and some other delicacies and in Nicaragua turtle hunting has even become a way of living.

In order to help these creatures scientists studied their migration, nesting and hatching habits and mating habits to help us learn more about them so we could save them from extinction. But will that be enough? Only time will tell, but current situation isn't giving much hope.
