Where the name comes from

Tragulus is the Latin diminutive of tragus, “goat”: “little goat”. Javanicus points to Java. In English it is the mouse-deer, and in French the chevrotain, “little roe deer” — three languages trying three different diminutives, all wrong, because it is neither deer nor goat nor mouse: it is the only living representative of a very ancient family, the tragulids, separated from all other ruminants for fifty million years.

Characteristics

  • 01

    It is among the smallest ungulates in the world: it weighs about as much as a rabbit.

  • 02

    It has neither horns nor antlers; the male has protruding upper canines.

  • 03

    Its stomach has three chambers instead of four: an incomplete ruminant.

What sets it apart

In Malay and Indonesian folklore it is the sang kancil, the trickster: the smallest and weakest creature of the forest, who defeats tigers and crocodiles by cunning. In the most famous story it must cross a crocodile-infested river, and persuades the crocodiles to line up to be counted, because the king is said to be sending food for all — then it hops across their backs one by one and reaches the far bank. It is the same archetype as the European fox and the African spider Anansi, applied to a two-kilo ungulate.
