Water Chevrotain

Hyemoschus aquaticus

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The water chevrotain is the only African tragulid and the largest of the family. It is not a deer: the tragulids are the oldest surviving lineage of ruminants, and they keep very primitive features such as the absence of horns and elongated upper canines in the males. It is nocturnal, solitary and always close to water: when chased it throws itself into the river and can stay submerged for several minutes, moving along the bottom.

Fun facts

  • GeneralIt hides underwater when chased, and represents a very primitive form of hoofed mammal.
  • When chased it submerges and walks along the river bed, breathing with only its snout out of the water: it can stay down for several minutes until the predator leaves.
  • The tragulids are the most primitive living ruminants: their lineage split about 35 million years ago and keeps features that deer and antelopes lost long ago, such as tusks instead of horns.
