Caribbean monk seal

The Caribbean monk seal (Monachus tropicalis) was formally pronounced as an extinct species in 1996. It was a water mammal with a gray upper and a white lower half. The species was once found surrounding the Caribbean Sea and fed on sea life such as fish and octopi. Its body was made up largely of blubber, with males generally weighing 170 kilograms and measuring about 210 centimetres, females being somewhat larger at 240 kilograms and 230 centimetres and pups typically weighing 16-18 kilograms and measuring about 100 centimetres. Columbus was amazed by the numbers of these seals when he first got to the West Indies.
