This picture has been taken by Paul Dixon, Australian Institute of Marine Science.  Paul was a member of a long cruise to the Coral Sea and Solomon Sea with Dr. Richard Harbison as chief scientist.  Paul used Richard's macroscope with a built-in ring-flash to photograph this live animal.  A similar photograph was used as cover picture for SCIENCE in 1982
