Mammals are warm-blooded vertebrate animals that typically give birth to live young, although five platypus and echidnas species lay eggs. There are approximately 5,400 species of mammals which range in size from the smallest bumblebee bat to the largest blue whale. Many mammal species populations are threatened by infectious diseases and man-made influences such as habitat loss, pollution, and climate disruption.
Arabian Oryx
The Arabian Oryx were considered extinct in 1972. Now there are more than 4,500 Arabian oryx in zoos and wildlife preserves.
Beluga Whale
Beluga whales are white, can turn their head in all directions, and can swim backwards.

Chimpanzee

Mexican Gray Wolf

North American River Otter
North American river otters were devastated in the late 1800's and early 1900's by trapping and habitat destruction.
Okapi
The near threatened okapi is a very elusive, unusual looking animal that has stripes on their hindquarters and legs like a zebra, but the rest of the body is dark brown.
Orangutan
The endangered orangutan is the world’s largest tree dwelling animal and the only great ape species native to Asia.
Polar Bear
Polar bears were hunted almost to extinction in the '60s and '70s. International protection has helped their population health, but climate disruption is destroying the sea ice they need to live.
