Front part of body of a prosn (Spirontocaris polaris) from above, showing on the right side a swelling of the carapace caused by the presence of the parasite Bopyroides hippolytes in the gill chamber--A. Female parasite extracted and further enlarged--B; Male parasite on the same scale as the female--C
This individual, found on the column of a Cribrinopsis fernaldi anemone in 2014, has a parasitic isopod Bopyroides hippolytes in the gill chamber. Animal total length = 3 to 3.5 cm.
This closeup dorsal view of the head (the animal is facing to the left) shows the supraorbital spines. Lebbeus groenlandicus has one supraorbital spine between the eye and the rostrum.
Lebbeus groenlandicus sometimes assumes this cataleptic posture when disturbed, but seems less prone to do so than is Paracrangon echinata. Photo by Dave Cowles, July 2000
