Crenilabrus melops Anilocra QEII channel 290907 23-930 smg
This long-spined sea scorpion, Taurulus bubalis, remained still while I took numerous photographs with a compact digital camera in an underwater housing. It had a parasitic isopod, Anilocra frontalis, attached to the right side of its body behind the pectoral fin. The picture shows that the fish appears to be sloughing off its skin. I do not know if this a consequence of the parasitic isopod. This member of the sculpin family was revealed when I turned over a boulder it was hinding under. Photographed in Belle Greve Bay on Guernsey's east coast on 19 February 2007. File No. BG 190207 6530 ©RLLord fishinfo@guernsey.net
This long-spined sea scorpion, Taurulus bubalis, was spotted nearby while finding a tompot blenny, Parablennius gattorugine; a five bearded rockling, Ciliata mustela; and two long-spined sea scorpions under one boulder in a shallow pool in Belle Greve Bay on Guernsey's east coast on 4 February 2007. This long-spined sea scorpion has a parasitic isopod, Anilocra frontalis, attached to the right side of the head. File No. 040207 5950 ©RLLord fishinfo@guernsey.net
This image shows two isopod skin parasites attached to a two-spotted goby, Gobiusculus flavescens, which was collected from the Belle Greve Bay sea-shore on Guernsey's east coast. The goby had a total length of 3.5 cm and was found with four Anilocra frontalis isopod parasites attached to it. One Anilocra parasite died and another fell off the fish before photography but two remained attached to the rear right flank near the tail. Collected and photographed on 3 March 2006 File No. 8-818 ©RLLord fishinfo@guernsey.net
This goldsinny, Ctenolabrus rupestris, was found in a Clive Brown crab pot off Guernsey's south coast on 18 May 2002. Attached to its nape behind the left eye is a large female Anilocra frontalis isopod. The male parasitic isopod has fallen off the fish but the damage done by the male can be seen in the loss of skin pigment and tissue. These skin parasites are found on a number of fish species in Guernsey waters. File No. 12-569 ©RLLord fishinfo@guernsey.net
This tiny female isopod, Gnathia maxillaris, is attracted by male pheremones to a crevice where it is dragged inside to join a harem of females. The adult female doesn't feed but is a vescile to carry eggs. The production of juveniles ruptures the female and leads to her death. This female was found without eggs on the sea-shore in a crevice with a male at La Valette on Guernsey's east coast. The body of the still-living female was completely hollow.
