This is one of the male gorillas from Bristol Zoo. Their outside space is surrounded by a moat. Gorillas will drown if they fall into deep water as their reaction is to curl up into a ball and sink to the bottom and drown. Now this young male tested the water with his foot and decided it wasn't too deep, sat down and starting having fun with the water! Never have seen this before! Speed should of been higher but this was an unexpected event!
