large, gelatinous species with a wrinkled surface and widely
scattered, small tubercles. Most animals are very dark brick-red
although a few may be light brown with white speckles on the tubercles.
The oral veil is tuberculate but lacks long sensory papillae.
At French Frigate
Shoals, fifteen animals were found in lobster pots baited with dead
herring suggesting that it's a scavenger. When held in buckets, some
displayed weak swimming motions. (Note 1) Most
were "infested" with commensal
copepods. (see photos) The
were set over a depth range of 80-242 m
(262-794 ft) with
a minimum depth range for the animals of 128-178 m (420-584 ft). It
has also been
photographed by HURL submersibles at depths of 212-389 m (696-1276

Observations and comments:
1: Based on the display of swimming
motions when held and the number found in the baited traps, it's
tempting to speculate that they may find food by detecting the scent of
a dead fish and swimming up the scent trail to its source.
