With fully grown adults being the size of a rabbit, the mouse deer is one of the smallest ungulates (animal with hooves) on Earth. It is called mouse although it’s not a mouse, and deer although it doesn’t have antlers – but it uses its canines to fight as other deer do, too. The fur of the mouse deer is mainly reddishbrown, with white markings on the neck, and the under parts are pale. The legs are delicate and slender but they can stomp heavily and loudly when agitated. These animals have a life span of about 12 years. Mouse deer are classified on the IUCN Red list as ‘least concern’.
