Endangered Animals in the Rainforest | Top 6 Endangered Animals

I’m often asked as to how many endangered animals in the rainforest. Therefore, I have decided to list down the most important facts about these endangered animals. They have become endangered due to extreme hunting, poaching, and scarcity of prey. Some species are affected by the climatic change. Scientists have introduced several species to the different regions in order to increase the numbers but it has also affected the native species already-living there. Unless some conscious efforts are not taken, these animals will continue to decline as they’re likely to become extinct in the next 15 or 20 years.

Endangered Animals in the Rainforest



Lemur is a primate native to the island of Madagascar. They are thought to emerge in Madagascar some 62 to 65 million years ago. In those times, lemurs could be as large as an adult gorilla of today. Currently, there are around 100 species of lemur. They can grow to a size of 30 grams (1.1 oz), with the weight measuring at 9 kg (20 lb). They are highly sociable animals among all primates and they communicate with scents and vocalizations. Lemurs have typically low metabolic rates and may display seasonal breeding including hibernation. They generally feed on leaves and fruits and are generally forest-dwelling species.

The black-faced lion tamarin is a small New World Monkey belongs to the family of Callitrichidae. They are critically endangered species and are native to the coastal forests of southeastern Brazil. There are no more than 400 individuals remaining in the wild. They show golden-orange color together with black head and legs. It was not discovered until 1990 when two Brazilian researchers: Maria Lorini and Vanessa Persson found it in the state of Parana. They largely live at an altitude of 40 meters (130 feet). These animals feed on small fruits, invertebrates, insects, spiders, and snails. Black-faced lion tamarin drinks nectar and eats bromeliads and mushrooms. They are found in groups comprising 2 to 8 members. The birth usually takes place in the months of September and March.
