Pelagic Amphipod
No full textSwimmingThis is a mesopelagic amphipod from the genus Cystisoma.
Based on the elongate first antennae, this beast must be Cystisoma latipes (Stephensen, 1918) or C. gershwinae Zeidler, 2003.
The wedge-shaped head in lateral profile indicates the former. C. latipes is not widely reported but appears to be pan-oceanic in lower latitudes and has been recorded from the western Indian Ocean.
It is almost transparent, the only pigment is the eye.
These are large amphipods: this specimen is probably about 50 mm in length
