4 of 6 great ape species listed as endangered
With the recent addition of eastern gorillas, four of the six great ape species are now listed as 'critically endangered' species by the IUCN. Eastern gorillas, the largest living primate, have seen a 70% decline in the last two decades, leaving only 4,600 specimens globally. Habitat destruction and poaching have been held responsible for the near-extinction of the species.
