35 Of The World's Rarest Animals

All of the species on this list are critically endangered and will disappear entirely — unless drastic measures are taken to save them.

1. 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.

This wombat's nose is very important in its survival since the creature has very poor eyesight and needs its nose to smell food in the dark.

2. Pygmy Three-Toed Sloth

This small three-toed sloth is endemic to Isla Escudo de Veraguas, a small island off the coast of Panama. A 2011 study found only 79 left in the wild.

3. 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)

cache.daylife.com

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.

5. Boni Giant Sengi (Formerly Known as an Elephant Shrew)

The entire population is estimated to be between 60–100 individuals living in two ponds in Mississippi. Unfortunately, the dusky gopher frog population has declined because of loss of wetlands and native longleaf pine habitat, the decline of gopher tortoises, invasive species, disease, drought conditions, and lack of natural and prescribed fire.

28. Singapore Freshwater Crab

The common sawfish lives in the coastal tropical and subtropical waters of the Indo-Pacific and Atlantic oceans. Currently, the common sawfish is largely restricted to northern Australia.

Rob Griffith / AP

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.

35. Tonkin Snub-Nosed Monkey

The tonkin snub-nosed monkey is endemic to Northeastern Vietnam, where there are fewer than 200 left.

Heavy poaching and the destruction of habitat have diminished this monkey's population.
