Northern Hairy-Nosed Wombat
There are about 115 northern hairy-nosed wombats left in the wild. They all live in Epping Forest National Park in Queensland, Australia.

3. Red-Crested Tree Rat

Red-Crested Tree Rat
The red-crested tree rat lives in the forests of Colombia. It was thought to be extinct for many years — until volunteers at the El Dorado Nature Reserve were visited by the creature in 2011. The last recorded sighting was in 1898, when two of the critters were found and studied, and were the subsequent source of all information about the rat.
This little critter is about 18 inches long, which is about the same size as a guinea pig. It inhabits a relatively small area of the forest in Colombia, and much of this area has been cleared or disturbed.

4. Angel Shark (aka Squatina Squatina)

Angel Shark (aka Squatina Squatina)
Historically, the angel shark range was from the Northeast Atlantic, Mediterranean, and Black Seas, but commercial fishing has diminished the population. It is now uncommon throughout most of its range with the exception of some areas of the southern Mediterranean and Canary Islands.
Camouflaged in the sand, an angel shark waits there for small fish to swim within gulping distance.
When an unsuspecting fish comes near, the shark lunges upward, sucks the fish into its huge mouth, and swallows it whole.

21. Vaquita

Vaquita
This is the world’s smallest dolphin, and is from the Northern Gulf of California and Mexico.

Sawfish have adapted to live in both salt and fresh water, while their long saw-like rostrum (nose) has evolved to expertly forage for food under the sandy ocean floor. Sawfish have been placed on the critically endangered list mainly due to a human impact to their environment and being entangled in fishing nets.
