Instantly recognised around the world thanks to their trunks and tusks, elephants are the world's largest land animals. African elephant males are the biggest of the bunch, weighing in at up to 6 tonnes, while smaller Asian elephants can still tip the scales at 5 tonnes.

Female elephants are social animals, living in herds with their relatives. Males usually live alone but sometimes form small groups with other males. All elephants need a lot of space, sometimes roaming over incredible areas to find enough food and water to sustain them.

But their habitats are shrinking. African elephant habitat has declined by over 50% since 1979, while Asian elephants are now restricted to just 15% of their original range.

Add in growing human-wildlife conflict and an upsurge in ivory poaching in recent years and it's easy to see why elephants are under threat.
