The marsh deer is a deer of South American wetlands. Elastic tissue between its hooves is suited to muddy ground.
Its hooves are large, with elastic skin between them. Only males have branched antlers, and the antlers are not shed at one fixed time of year.
It feeds on grasses and leaves near water. In the wet season it spreads across flooded areas; in the dry season it tends to gather near permanent water and reeds.
