ENDANGERED ANIMALS!

The red wolf is classified by the IUCN as an animal critically endangered (2008), is that these wolves there is only one reintroduced population in northeastern North Carolina, USA in an area that has 6,000 km ², as this species became extinct in the wild in 1980, being re-introduced by the United States Fish and Wildlife Service (USFWS).
In 2007 there were approximately 207 captive individuals in the U.S. and less than 150 in the wild. Of copies are reintroduction outside of numbers have not reliable.

Not to be confused with other species known locally as the red wolf Cuon or red dog (Cuon alpinus) and the maned wolf or maned wolf (Chrysocion brachyurus), sometimes called red wolf in Brazil.

Diversification of sharks is huge, since it appeared as the first shark for 400 to 350 million years to the present have appeared no less than 368 species distributed in 8 orders, plus most of these species existed in the period Jurassic, so they are considered living fossils.

Hammerheads down the order specifically Carchariniformes unlike the white shark (Carcharodon carcharias) is the order of Lamniformes; within the order of hammerheads are nine species in two genera.

The great hammerhead (Sphyrna mokarran) is a shark considered endangered by the IUCN in 2007. Previously, due to the lack of information about the fish had no defined status. This indicates the crucial need to study the species, and that greater knowledge of these leads us to know your threats and if necessary help preserve them before it's too late
