Velvet Swimming Crab Living Rock Rock Goby
 
On the beach by the Half Brick at east Worthing, a dozen or more Velvet Swimming Crabs hid under large boulders with a fairly usual collection of rock pool life including one Oyster bigger than my hand, three large Chitons, Acanthochitona crinita, (a small mollusc), a 20 cm green Atlantic Eel, and adult and a juvenile 5-Bearded Rockling,Ciliata mustela, and frequent Piddocks (a bivalve mollusc) burrowing in the chalk boulders. Snakelocks Anemones, Anemonia viridis, were frequently seen, more often overlooked, with Sand Gobies Pomatoschistus minutus, noted in the shallow sandy pools, a few Rock Gobies Gobius paganellus,Shore Crabs, small Squat Lobsters, and a handful of Hairy Crabs. On the underside of boulders, there were hundreds of the tiny Long-clawed Porcelain Crabs. Less obvious were colonies of Star Ascidian and bryozoans coating the rock surfaces.

A morning low tide visit to the beach by the Half Brick (East Worthing) was not very fruitful and the only fish of note was a baby pipefish discovered by Katherine Hamblett. Althought it was too small to be positively identified it was probably a Worm Pipefish, Nerophis lumbriciformis, which was unusual this far east up the English Channel, but it is increasing being discovered along with the Daisy Anemone, Cereus. Snakelocks Anemones, Anemonia viridis, were frequently seen, at least twenty were noted. There were occasional small Beadlet Anemones, Actinia equina, mostly of reddish-brownish hues.

In the shallow pools nearest the shore, there were shoals of very small bottom living fish. These were the young Common Cobies, Pomatoschistus microps. There were a handful of larger gobies and these were Rock Gobies, Gobius paganellus.

The largest of the local chitons, the mollusc Acanthochitona crinita was discovered on the underside of a rock.

Shore Crabs were seen more often than usual on this shore and there were a dozen medium-sized ones. Other crabs were much less than usual with just a handful of Hairy Crabs and small Edible Crabs. Very small Squat Lobsters and small Common Hermit Crabs (in topshells) were both frequently seen. Mysids and Hooded Shrimps Athanas nitescens, were seen under rocks with very frequent Long-clawed Porcelain Crabs on the underside of rocks and boulders (but only suitable rocks comprising about 5% of the promising ones searched). Small prawns shot backwards in the shallow pools. Large ragworms lived in the holes in a few of the chalk rocks.

The beach between Worthing and Lancing seems an unpromising area for rockpooling but it consistently provides a variety of some of the less usual small fish and crabs found between the tides. Katherine Hamblett and Tacita French discovered a young first year Worm Pipefish, Nerophis lumbriciformis, which is unusual this far east up the English Channel.

There were unusual crabs (photographed above) as well as more common crustaceans like small Common Hermit Crabs, Pagurus bernhardus, and Squat Lobsters, Galathea squamifera, one Short-legged Spider Crab Eurynome aspera, and a handful of small Long-legged Spider Crabs, Macropodia rostrata,

Sea Anemones on this shore included at least a handful seen of Daisy Anemones Cereus pedunculatus, (with mauve/purple columns), and Snakelocks Anemones  Anemonia viridis, which both reach their most easterly shore distribution at Lancing.
