cross river gorilla



there are only about 200 to 300 of these gorillas left in the wild.

They are critically endangered.


The population risks inbreeding and a loss of genetic diversity because there are so few Cross River gorillas and they live in groups that interact infrequently if at all.


The hunting and killing of gorillas is illegal in Cameroon and Nigeria, but enforcement of wildlife laws is often lax. Following conservation efforts, hunting has declined to a low level, but any amount of gorilla killing will have a significantly impact an already small population.

The population of Cross River gorillas declined by 59% between the years 1995 and 2010, a greater decline over that period than any other subspecies of great ape. Apes such as the Cross River gorilla serve as indicators of problems in their environment and also help other species survive. The decline of this species started thirty years ago and has since continued to decline at an alarming rate. The danger of hunters has led these creatures to fear humans and human contact, so sightings of the Cross River gorilla are rare.


the discovery of the subspecies fighting back against possible threats from humans. They found several instances of gorillas throwing sticks and clumps of grass. This is unusual. When encountered by humans, gorillas usually flee and rarely charge.

Their diet usually consists of fruit, but in fruit scarce months, (August–September, November–January) their diet is primarily made up of terrestrial herbs, and the bark and leaves of climber and trees. Many of the Cross River gorilla food sources are very seasonal and thus their diets are filled with very dense, nutritious vegetation that is usually found near their nesting sites.
