Eastern gorilla
The eastern gorilla ("Gorilla beringei") is a critically endangered species of the genus "Gorilla" and the largest living primate. At present, the species is subdivided into two subspecies. Grauer's gorilla, formerly known as the eastern lowland gorilla ("G. b. graueri") is more populous, at about 3,800 individuals. The mountain gorilla ("G. b. beringei") has only about 1000 individuals. The International Union for the Conservation of Nature mentioned illegal hunting in its assessment of threats to the species.
Largest prehistoric animals
There is much controversy over the largest-known of these reptiles. Fossil remains of a pliosaur nicknamed as "Predator X" have been discovered and excavated from Norway in 2008. This pliosaur has been estimated at in length and in weight. However, in 2002, a team of paleontologists in Mexico discovered the remains of a pliosaur nicknamed as "Monster of Aramberri", which is also estimated at in length. This species is, however, claimed to be a juvenile and has been attacked by a larger pliosaur. Some media sources claimed that "Monster of Aramberri" was a "Liopleurodon" but its species is unconfirmed thus far.
Another very large pliosaur was "Pliosaurus macromerus", known from a single incomplete mandible. It may have reached , assuming the skull was about 17% of the total body length.
