Female dominance over males is rare among mammals, including primates, but it's the norm for lemurs.

This deer is the most threatened deer species in the world. They have no surviving predators in the wild. Their biggest threat today is humans.  

The red-bellied lemur is one of the world’s rarest primates. Only the males actually have red bellies - the females have white.

Meet the roan antelope - a bold and powerful grazer of Africa’s vast savannahs. With their striking black-and-white facial markings, muscular build, and metre-long horns, these antelope are built for survival. They live in tightly bonded herds, where dominant males defend their groups in dramatic, head-clashing battles. Although listed as Least Concern on the IUCN Red List, their numbers are shrinking in parts of their range due to habitat loss, hunting and climate change.

Roloway monkeys definitely stand out: they are quite large, have a triangular face, black and white coat, a pointy beard and yellow thighs and bum.

These large, nocturnal mammals have distinctive cat-like facial features and a prehensile tail, earning them the nickname 'bearcat'.

They are members of the pig family but in Indonesia, their name means pig deer after their unusual appearance!

The blesbok is a distinctive antelope species native to South Africa’s grasslands, easily recognised by the bold white blaze on its face. Once hunted to the brink of extinction, conservation efforts have helped restore its numbers. These social, territorial grazers play a crucial role in maintaining healthy ecosystems. At Chester Zoo, we support conservation initiatives to ensure their continued survival in the wild.

Recognisable by its oversized ears, this species is uniquely adapted to its environment.

These monkeys are known for their strong social bonds, often seen grooming and cuddling with their lifelong mates.

The naked mole-rat is one of the most extraordinary mammals on Earth. Native to the dry grasslands of East Africa, these near-hairless rodents live entirely underground in vast tunnel systems.

Despite the fact that the rock hyrax is about the same size as a guinea pig, its closest living relative is the mighty elephant!
