A tropical fish never seen before off New Zealandâs coast was discovered at the Poor Knights Islands marine reserve. The Department of Conservation was using a remote-operated camera when it discovered the small damselfish swimming at about 80m in the reserve. Dr Debbie Freeman, scientific officer and marine biologist, said the damselfish was a subtropical species normally found in 90-152m depth, and between 26-30 degrees latitude south. Dr Freeman said the Poor Knights was about 35 degrees latitude south, so the fish was a long way south of where it would normally be. The damselfish has been found in Australia, the Norfolk Ridge and the Kermadec Islands.
