Small deer from south east asia that were introduced as an ornamental deer in the early part of the 20th century.
The females are in season continually and are essentially in a continuous state of pregnancy. A single young is born each time meaning that a female can produce 1.5 offspring a year.
Adults grow to a height of over 40cm and a weight of 11-16kg. A distinguishing feature of the adult male is its large canine teeth or tusks which may reach 3cm in length. They are a very successful introduced species and are able to survive on many different habitat types with a favouring of dense woodland. Their distinctive call is a sharp high pitched bark. There is evidence that they are also moving into urban environments.
