SAVE THE SEA TURTLE!!!!









Sea turtles are reptiles with shells that have existed for over 150 million years and survived all the changes on the planet.
 
They live in temperate or warm seas. Of these species, five are located in Brazil. In the Andalusian coast there are specimens of two species, the leatherback and loggerhead turtle. The remaining species are the green turtle, hawksbill, olive ridley turtle, Flatback turtle and olive.Sea turtles are generally solitary animals that spend 90% of their time at sea.
 
The first 48 hours of life of sea turtles are crucial. Since coming out of his shell beach combisystems must travel to the sea on their own bootstraps. This means saving predators besides having to get their own food. Their diet consists of 90% algae, but they get to eat some fish, jellyfish and small crustaceans.





Already in the open sea, sea turtles have to cope with strong currents. For this reason, your vision is limited.A unique ability of sea turtles is to migrate and then be able to return to the same beach to nest. Sea turtles reach sexual maturity around 7-8 years.

CAUSE OF IT IS EXTINCTION



One of the main causes of extinction are trading in their meat and as pets.Man killed turtles to extract everything in it, meat, skin, shell, eggs ... Thus there have been massacres of turtles and most are now extinct. Currently, the nesting beaches preserved as national parks and protected reserves.Turtle eggs are eaten in India. In South America, the oil extracted from the turtle has a great value as lamp oil. Elsewhere in the shell used to make musical instruments. But they paid a great price with the massacres, in three centuries, killed 100 million green turtles.Today is educating the world's population to assist in the protection of these animals also are implementing a new technique for fishing nets TED (Turtle Exclusion Device, turtle excluder device) which allows turtles go of fishing nets. WWF is also helping to protect sea turtles, at higher risk of extinction, making donations to organizations that protect them.
1. Poaching: Thirty-five thousand animals are killed annually pirate fishing. Between 8 and 9 000 die in the season of Lent and Easter, to feed those who do not want to eat meat on Fridays in Lent and believe that sea turtles because nothing is fish. Turtles are reptiles - the oldest surviving in the world - and are red meat.2. COLLECTION OF EGGS TO EAT:Although it is also illegal to remove eggs from a nest, it is very common because eating these is considered an aphrodisiac. In a nest containing 100 eggs, only one to five turtles that hatch survive to maturity. The practice of eating eggs is also destroying turtle populations.




3. Bycatch: Sea turtles need oxygen to survive, hence, are very vulnerable to drowning, especially in fishing nets. Many turtles suffer for hours, struggling to escape from fishing nets, and eventually drown.



4. DEVELOPMENT COSTS: Modify and coastal habitat loss of their home regions is another threat to the turtles. The lights of buildings on the coast can disorient the turtles that come ashore to nest, and several beaches historically used for nesting have been completely destroyed.






5. POLLUTION: Turtles can accidentally choke when they eat plastic bags or other trash, which seem jellyfish - a normal part of the diets of several species of turtles. Also the discharge of pollutants and chemicals between the ocean affects the health of turtles.




We invite you to avoid doing what esxtincion causes of sea turtle.
