Stags shed and completely regrow their antlers every year, one of the fastest-growing tissues known in any mammal.
From Red Deer
The rut — known in Spanish as the berrea — is its most spectacular moment: in autumn the stags roar to gather and hold a harem, walk in parallel with a rival, sizing each other up, and only come to an antler fight if neither gives way.
From Red Deer
That deep roar is an adaptation to the forest, where sound matters more than visual display.

One of the smallest hoofed animals in the world at 2 kg, and the cunning hero of Malay folk tales.
From Javan Chevrotain
It is the smallest ungulate in the world: an adult weighs the same as a small rabbit and its legs are as thin as pencils.
From Javan Chevrotain
In Malay and Indonesian folklore, the sang kancil is the hero of dozens of folk tales: a little animal that always defeats tigers and crocodiles by cunning, the local equivalent of the European fox.
From Javan Chevrotain
It keeps its spotted coat all its life, and is the Bengal tiger's main prey.
From Chital
It follows the langurs through the forest to eat the fruit they drop, and in return benefits from the alarm calls the monkeys give from the canopy on seeing a tiger: an alliance between a primate and a deer that works both ways.
