There are over 5,000 mammal species in the world, and we have some of the most exotic and endangered in the world.
Mammals are air-breathing animals, characterised by having hair or fur. Females possess mammary glands, which are used for suckling their young.
We have over 1200 individual mammals from more than 75 different species, ranging in size from our tiny sengis up to our enormous Asian elephants.
Many of the species that we specialise in, like the black rhino, are in danger of becoming extinct in the wild in the next 25 years. The work done in the zoo with these species is helping to protect their future.
