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’. Ian Wallace World Museum Liverpool All local sewage is treated so sewage-related items should be rare but note that William Brown Street, LIVERPOOL dog droppings are present on many beaches.

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.

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.
