New Forest adder swimming in river caught on film

An "incredibly rare" sighting of an adder swimming in the New Forest has been filmed by the South's Inside Out team.

Britain's only venomous snake was seen at the Lymington Keyhaven Nature Reserve and is occasionally known to swim. It is thought to be one of the first times it has been captured on camera.

Warden Pete Durnell said: "This is a very unusual sighting. Adders are fairly common on the reserve but it's extremely rare to see them entering the water like this and not something I have witnessed."
