Measurements: head and body, 1.5 to 2 m. Weight: 140 to 320 kg.
4. Causes of extinction (Grizzly bear) In Mexico, hunting and environmental disruption are many species to the brink of its disappearance.From the earliest times, mankind has made use of wildlife selectively killing or capturing some of the species belonging to it or to get rid of harmful species (snakes, rodents, etc..) Or to use its meat as food and their skins as clothing.This noble species is the true symbol of independence wild and rugged freedom is on track to extinction under the guise of "progress";
6. Manatte (characters) Vaquita common name or Manati Animal Kingdom Phylum Chordata Mammals Class Scientific name (genus and species) Amazonian Manatee Trichechus manatus Trichechus senegalensis
7. description of the Manatte The sea cow, as it is sometimes called the manatee, is a seal-like animal, slow-moving and living in shallow water. Usually has three or four feet long, weighs between 400 and 600 kilograms, is gray-brown, with thick and nearly hairless, big tail shaped blade which serves to drive. You have only two limbs, represented by the front wings used to be that algae and other aquatic plants at the mouth to catch them with his lower lip lobed. The manatee's body is big and sturdy but hydrodynamic, because these animals never leave the water. His head is large, his nose is very wide and the upper lip is flaccid, lacking pinna and appears only a small hole behind the eyes. His eyes are small and lack eyelids. The front legs have become flippers which are supported by five flat fingers, which end in small flat, round nails like claws. The hind limbs have disappeared and in the back of the body, a tail is formed by two horizontal lobes somewhat flattened, which are responsible for promoting the manatee in the water. His skin is very thick, introduced changes in the digestive system like all plant-eaters, such as the intestine, this is very long and are microorganisms that help to metabolize cellulose.

10. Causes of extinction The hawksbill turtle, Eretmochelys imbricata, is listed as "critically endangered" species. Some biological characteristics, such as the complex life cycle, longevity and late maturity, habitat and diet specialist and extensive migration, measures to hinder their recovery. The hawksbill nests in Venezuela in a number of secluded beaches, but mainly in the offshore islands and the Peninsula of Paria. Hatchlings live pelagic environment, passively drifting turns and faces the Caribbean, little-known sites and duration until reaching about 20m in length, when they come to occupy shallow-generally associated with coral reefs. Juveniles live in these environments at least two decades, continents groups originating from different nesting in the region. Adults remain on the reef, feeding mainly on sponges, in bi-i tri annual cycles, reproductive and they migrate to nesting beaches. The hawksbill face numerous threats. Hunting, primarily for its shell, used to make various objects, led the international trafficking of hundreds of thousands of shells during the years he was legal, drastically reducing their populations. Hunting still continues illegally, as well as incidental catches in fisheries. Pollution affects in different ways all environments occupied by the tortoise and its main habitat, coral reefs, is one of the most threatened ecosystems in the region. The "Action Plan for Recovery of Marine Turtles of Venezuela" contains several measures to achieve recovery of the species Na in the mid and long term (AU)
