🦍Western gorilla
O gorila-do-ocidente (nome científico: Gorilla gorilla) é a espécie mais comum do género Gorilla. Grande e robusto, com machos pesando cerca de 168 quilos, a espécie é encontrada em uma região do centro-oeste da África, geograficamente isolada do gorila-do-oriente (Gorilla beringei). O pelo da espécie ocidental é significativamente mais claro. O gorila-do-ocidente é o segundo maior primata vivo depois do gorila oriental. Duas subespécies são reconhecidas: o gorila-ocidental-das-terras-baixas (Gorilla gorilla gorilla) é encontrado na maior parte da África Ocidental; enquanto o gorila-do-rio-cross (Gorilla gorilla diehli) é limitado a uma área menor no norte, na fronteira de Camarões e Nigéria. Ambas as subespécies são listadas como criticamente Ameaçadas.

Bite force1,723 NDetails ↓Hide ↑
MODELLED by 3D finite-element analysis, bite at the second molar; adult female specimen, estimated 127.5 kg. No bite force has ever been measured in any great ape. An independent enamel-chip fracture method gives 1693-2865 N (Constantino et al. 2010, Biol Lett 6:826).
