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.

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.

4. 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.

8. Gooty Tarantula (aka Metallic Tarantula)

The spider's habitat is in Southeastern India and Sri Lanka. Habitat loss and degradation as a result of deforestation, firewood collection, and civil unrest have all contributed to the loss of this tarantula's population.

20. Luristan Newt (aka Kaiser's Spotted Newt)

The luristan newt is a type of salamander and is endemic to the southern Zagros Mountains in Iran. The luristan newt is coveted in the pet trade — they were sold on a Ukraine website for $300 — and now only survives in captivity.

23. Greater Bamboo Lemur

There are only 100–160 individuals left in the southeastern and southcentral rainforests of Madagascar. The major threat to this animal is slash-and-burn agriculture, mining, and illegal logging.

26. Red River Giant Softshell Turtle

This enormous weighs 440 pounds. Unfortunately, there are only four red river giant softshell turtles left, all of which live in captivity. The animal is considered sacred by many Vietnamese.

27. Dusky Gopher Frog

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.

29. Madagascar Pochard

The hirola antelope found in arid grassy plains in a pocket on the border between Kenya and Somalia. There are between 500 and 1,200 of them left in the wild.

34. Common sawfish


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.

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.
