We share our planet with such a vast variety of living things, that it’s sometimes easy to forget that many of them are on the threshold of extinction.

Whether due to pollution, habitat loss, or hunting, there are some wonderfully strange creatures that are at risk of disappearing from the face of our planet entirely. Here are some of the creatures that our children may never get to see when they grow up.

1. The hooded seal

The hooded seal of the the North Atlantic Ocean is known for the striking nasal cavity located on top of its head. Hooded seals are a favored target for hunters

2. The dugong (The sea Cow)

The dugong is one of four species of Sirenia, more commonly known as sea cow.They’ve long been hunted for their meat and oil.

3. Hog-nosed bat:

Kitti’s hog-nosed bat, otherwise known as the bumble bee bat, is the smallest known species of bat and one of the smallest mammals on earth. They’re in danger due to deforestation in their native Thailand.

4. The saiga antelope:

 The saiga antelope of the Eurasian steppes has been in danger for quite some time due to widespread hunting. A single one of their horns, said to posses restorative powers, can sell for as much as $150. A recent deadly epizootic plague has pushed them into “critically endangered” status.

5. The Olm:

 Found primarily in central Europe, the olm is the only amphibian that spends its entire life under water. Its eyes are undeveloped, but it has an incredible sense of smell and hearing. It is endangered due to pollution and other drastic changes to their environment.
