Eastern Cougar Believed To Be Extinct, Probably Has Been For Over 70 Years

Sadly, entire populations of animals can vanish from the planet without anyone noticing. That appears to be the case with the eastern cougar.

The U.S. Fish and Wildlife Service has performed extensive research covering the cougar's traditional U.S. and Canadian habitats. They've determined there the animals likely haven't been in existence for over 70 years. It's been suggested that the cougar sub-species be removed from the endangered list and declared extinct.

The large felines now occupying the regions once dominated by the eastern variety migrated there from the western United States and Florida. The demise of the eastern cougar was first acknowledged in 1973, the year it was placed on the list of endangered species. Troubles for the animal are believed to have begun in the 1800s. At the time they were plentiful, and thus commonly shot by settlers wanting to protect themselves, their families, and their livestock. That, combined with the depletion of their primary source of food, the white-tailed deer, led to a significant population reduction.

The last eastern cougar sighting is believed to have occurred in 1938.

Axolotls are seen in a cage where scientists of the Biology Institute of the National Autonomous University of Mexico (UNAM) are reproducing them at an experimental canal of Xochimilco in Mexico City February 13, 2014. Scientists at UNAM's Biology Institute have warned the Axolotl (Ambystoma mexicanum) or Mexican salamander, could be at risk of extinction in the wild in five to 10 years as axolotl populations were declining in 2003. But a few canals in the southern Mexico City suburb of Xochimilco, the only waterways where some axolotls may still live, are threatened by pollution caused by the city's continuous expansion and the days of the species in the wild are numbered. The axolotl is now on the endangered species list of the Convention on International Trade in Endangered Species (CITES).

A Dendrobates leucomelas frog is pictured at a terrarium in Caracas November 30, 2015. Venezuelan frogs and toads are in critical danger due to climate change as rising temperatures complicate reproduction and spread a deadly fungus, say scientists, who liken the species to canaries in a coalmine warning of imminent danger. The survival of a group of nearly 20 frog and toad species, which top Venezuela's list of endangered species, may rest on a small group of academics in a Caracas laboratory attempting to recreate the amphibians' natural reproductive conditions.

A giant soft-shell turtle which is considered a sacred symbol of Vietnamese independence is guided into a cage for a health check by handlers at Hoan Kiem lake in the heart of Hanoi. Thousands of onlookers cheered in central Hanoi on April 3, 2011 when rescuers captured for treatment the ailing and ancient giant turtle. Legend has it that the turtle is the guardian of a magical sword once used in the 15th century to drive out Chinese invaders. Concern has mounted in recent months over the health of the animal likely to be over 100 years old and one of the last of a critically endangered species -- it is one of only four Rafetus swinhoei turtles known to exist in the world.
