The world's largest primate, western gorillas weigh up to 180 kg and inhabit the tropical and subtropical forests of equatorial Africa. Primarily herbivorous, living in family groups led by a silverback male who protects the troop and mediates social conflicts. Critically Endangered, with populations threatened by deforestation, poaching for bushmeat, and outbreaks of Ebola virus disease.

Pigeon biset

Among the world's most successful birds, rock pigeons are native to sea cliffs and caves of Europe, North Africa, and South Asia but have been domesticated for thousands of years and introduced globally to every urban center on Earth. Their exceptional homing ability — navigating thousands of kilometers using magnetic fields, sun position, and landmarks — has made them vital military messengers and racing sport birds. Today, feral populations inhabit every major city worldwide.
