Roehampton Zoologists to provide new home for endangered iguana species

Roehampton Zoologists are playing a key role in a project to reintroduce the endangered Lesser Antillean Iguana to an island in the Caribbean – and they will monitor the animals’ future progress using miniature radio transmitters.

Social networks are a matter of life and death…if you are a monkey!
