We went to a resort while in Rarotonga to catch up with a friend, when this Rock Fish was pulled out of the lagoon where tourists where swimming. If you stand on them you can get quite sick as they have long spikes on their backs that raise when they think they are being attacked. Everyone is advised to wear Aqua shoes or flippers while swimming just incase one is around. I think it is also known as a Scorpion Fish. Very ugly bull dog face. (The bull dog pulls it off and looks cute this thing didnt lol)
