2. Western Gorilla/Cross River Gorilla
Status: Critically Endangered. Extremely high levels of poaching and hunting have dwindled the population. By 2046, experts believe the Western Gorilla population will be reduced by more than 80 percent. There are two different main gorilla species with their own sub-species. One of the subspecies of Western Gorillas is the Cross River Gorilla — both are labeled as critically endangered.
