sealord > A selection of marine life found in Belle Greve Bay on Guernsey's east coast. Top row left to right: sea anemone prawn, Periclimenes sagittifer, found on the snakelocks anemone, Anemonia viridis, in Belle Greve Bay on the 20 March 2007. The nudibranch, Janolus hyalinus, found under a boulder covered in crustose coralline algae in a mid-shore tide pool on the 17 February 2007; and a masked crab, Corystes cassivelaunus, dug up from the beach and photographed on the 20 February 2007. Middle row left to right: A sand goby, Pomatoschistus minutus, buried in the sand and photographed on the 20 February 2007; a candy-striped flatworm, Prostheceraeus vittatus, photographed in a tide pool on the 5 February 2007; and a female worm pipefish, Nerophis lumbriciformis. Bottom row left to right: long-spined sea scorpion (a sculpin), Taurulus bubalis, photographed in a tide pool on the 4 February 2007; the nudibranch, Hermaea bifida photographed on the 15 February 2006; and a stalked jellyfish, Haliclystus auricula, attached to eel grass, Zostera marina and photographed on the 5 November 2006.
sealord > The less furrowed crab or Risso's crab, Xantho pilipes, is the least common of the three xanthid crabs found intertidally in Guernsey. The much smaller hairy crab, Pilumnus hirtellus, is much more common and the larger chocolate-brown coloured Xantho incisus, is slightly more common. Xantho pilipes can be easily separated from Xantho incisus because it has a thick line of setae (hairs) on its rear pereiopods (legs). Xantho incisus has far fewer setae. This specimen was found under a boulder in Belle Greve Bay on 20 March 2007. File No. BG 200307 22-893 ©RLLord fishinfo@guernsey.net
sealord > Normally the snapping prawn, Alpheus macrocheles, is found subtidally but this individual was found under a cobble in a gully by Quaine rock in Belle Greve Bay on Guernsey's east coast. It was found at extreme low water during a big spring tide on 20 March 2007. The snapping prawn is well-named for the loud sound it can make when alarmed. It makes this sound by snapping the heavy dactyl of the left claw against the propodus, which causes a cavitation in the water. The startling sound resembles a cluck that can be made by moving ones tongue over the roof of the mouth. File No. BG 200307 5-893 ©RLLord fishinfo@guernsey.net
sealord > The polychaete worm Nereis fucata forms an unusual relationship with the hermit crab, Pagurus bernhardus. The worm seeks out a hermit crab inhabiting an empty whelk shell by sensing when the hermit crab walks over the substrate. The worm will quickly come out of the substrate and penetrate the interior of the whelk shell. Sometimes the hermit crab will catch the worm before it can accomplish this. If the worm is successful in entering the whelk shell it will build itself a cocoon near the apex of the shell. When the hermit crab feeds the worm emerges from the shell to try and steal the hermit crab's food. The hermit crab often uses one of its right legs to push the worm back in the shell but eventually the worm will reach the hermit crab's mouth and steal the food.
