It is characterized by its distinctive antlers, which have multiple tines and can grow quite large in males. This deer typically inhabits grasslands, wetlands, and forest edges, where it feeds on grasses, leaves, and aquatic plants. Eld's deer are social animals, often found in small herds. They are known for their striking appearance, with a reddish-brown coat and white markings on their face and legs. Due to habitat loss and hunting, Rucervus eldii is classified as endangered, making conservation efforts crucial for its survival.
