Relatively large-sized deer, with a narrow face and long, thin legs; bushy tail. Legs black up to the radius. Muzzle black, white ring around eyes. Yellowish tail with black tip. Fawns unspotted. Permanent dentition of 32 teeth. Preorbital, nasal, rear interdigital, and tarsal glands are present. Antlers of adult males are typically fourto five-tined, 40-45 cm long, with radial branching; the main beam bifurcates not far from the base and each tine tends to bifurcate. Yearling males have simple spikes; two-year-old subadults have forked beams. Antler casting occurs in almost every month of the year, with a peak in September. Hooves are elongated; the pads of the hoof are connected by a strong membrane and can be spread up to

Jaguars (Panthera onca), Pumas (Puma concolor), caimans and anacondas may prey on full-grown Marsh Deer; Maned Wolves (Chrysocyon brachyurus) may prey on fawns.
