ANIMAL SPECIES:Undescribed Anglerfish
This undescribed species of anglerfish is currently being formally named by world expert Dr Ted Pietsch.
Identification
This undescribed species of anglerfish has bumpy skin that resembles the sponges among which it is often found. This camouflage is enhanced by the presence of smooth, dark spots on the body of the fish that resemble the pores on the surface of a sponge.
The fish was brought to the attention of the Australian Museum when the upper image, taken by Dr Rob Harcourt was sent for identification. Museum staff could not identify the fish, so forwarded the image to anglerfish expert Dr Ted Pietsch who stated that the fish may be a new genus. Dr Pietsch requested that the fish be collected and sent to him for examination. Dr Harcourt and dive buddies R. Fea and J. Coombs, applied for and were granted a DPI Fisheries permit to collect specimens. After a long search one specimen was collected. Since then, the team have dived many times without managing to find another fish.
Dr Pietsch needs more specimens before he can formally name this new fish. If you see an anglerfish that looks like the fish in the images, please take care to record the locality in detail and contact Mark McGrouther.
