16 of the Planet’s Most Endangered Animals

The bad news: there are fewer than 60 Amur leopards in existence. The good news: they reside in Russia’s Land of the Leopard National Park, where conservation efforts may help preserve their long-term survival.

Although on the verge of extinction, recovery efforts have bolstered the black-footed ferret population to 300 -- and counting -- across North America. It's a start!

Much focus has been placed on Western Silverbacks this week after 17-year-old Harambe was put down when a toddler fell into his enclosure. This species of gorilla is considered 'critically endangered' as a result of agricultural expansion and illegal poaching.

Sure, there's an NHL team named after them, but these south Florida felines are on the verge of extinction due to poaching and vehicle collisions. Estimates say there are only 160 left.

Deforestation has been the enemy to these unique-looking simians. Their population has dropped by 50% over the past 40 years.

We can blame trophy hunters for the fact there are only about 2,500 markhors remaining. The majority reside in Pakistan.

Quokkas are friendly marsupial found primarily in southwestern Australia. In this instance, their dwindling numbers are due to attacks from other animals, such as foxes and dingoes.

Also known as giraffe zebras, okapi are exclusively found in the Democratic Republic of Congo. Fewer than 20,000 remain.

Located in Central American lakes, these minuscule amphibians have been on the endangered species list for the past six years.

Thought to be extinct until 2002, these unique creatures are still around, although barely. The reason: many not-so-bright folks believe their body parts can cure leprosy and ward off curses. Ugh.

These Eurasian mammals are quickly vanishing. The culprit: hunting and a significant decrease in their natural habitat.

Yes, the're actually kangaroos and they really live in trees. Particularly in the rainforests of New Guinea and Queensland. Sadly, hunting and deforestation have reduced their numbers to nearly zero.
