This red jellyfish was captured simultaneously by two different cameras on ROPOS. The left half is from the HD video camera; the right half is from the 3-chip CCD still camera. Observation taken at 1395m, 4 September 2009.
A comment on flickr by neptunecanada:
It is most likely that this is the very rare Gran Rojo Jellyfish. It has only been seen about 2 dozen times and was first discovered in 2003.
