Health and Safety The greatest danger is being cut off by a rising tide so you are strongly recom- mended to only investigate on a falling tide. There are quick sands and also sand-covered soft mud, so if you start sinking in — retreat. Three species of Jellyfish, (Lion’s Mane, rare Blue Lion’s Mane and internal parts of the Barrel), and the Weever Fish can give painful stings and they should not be handled. Piles of marine debris may conceal sharp man- made objects. Dead and dying life is common and presents a food-poisoning risk so clean hands with soap and water or antiseptic wipes before touching the mouth or food. Before starting, cover cuts and abrasions with ‘Elastoplast’.

(Hand lens good to see more of your finds) Smaller Colwyn Bay and Fleetwood bags are useful to build up a collection of durable finds. Note - Colour may vary from that shown and they may be blackened Shells can be collected into any suitable water-proof bag e.g. Supermarket - The size given is the largest that species normally grows Carriers * indicates there are rarer species that also look a bit like this (These are covered by additional notes available from www.record-lrc.co.uk) Centimetres Animals that are alive in the sand and in water Animals that are buried can be revealed by digging up a trowel-full of sand plac- 1 ing it into the kitchen sieve then washing the sand through the sieve by placing it up to its rim, but not above, in water and moving it from side to side. Note that 2 this does not usually work for stiff mud. Any net will catch animals that cannot pass through its mesh. Fine nets clog, but 3 Common Whelk Red Whelk Dog Whelk Buccinum undatum coarse nets let too much escape. A mesh of about 2 mm is good. Neptunea antiqua Nucella lapillus Up to 9 cms Up to 10 cms Up to 3.5 cms 4 (see also page 6) (see also page 6) To see your captures easily, place the contents of your net or sieve into a little water in the cat litter tray. The tray is also useful to lay out other beach finds for examination. 5 Best places to look for buried life 6 Life can be sparse in the dryer sands of the upper shore. Wet sand, for example at the edge of channels can be good but NB such areas can also be quick 7 Sting Winkle Common Winkle * Flat Winkle sands.

This can be done on the beach or by putting them into a bowl filed with sand and water. However, release them afterwards as sandy-shore life is very difficult to keep in 10 aquaria. ..... and finally Tower Shell Wentletrap Grey Top Shell (group) Turritella communis Epitonium clathrus Gibbula cineraria You will encounter lots of black sand under the surface, and shells that are bur- Up to 5 cms Up to 3.5 cms Up to 1.5 cms ied also go black.
