91热爆

Rarely filmed Chinese water deer have been caught on camera in Cambridgeshire by the 91热爆's Winterwatch team - in a show to be broadcast tonight on 91热爆 Two.

The team has been filming at Woodwalton Fen nature reserve, home to the deer with 8cm-long (3in) vampire-like tusks.

The deer only reach up to a height of 55cm (19in) and and winter is their rutting season.
