This isn't surprising. Martin is a wildlife ranger who works for Forest Holidays down in the West Country of England, is a regular visitor to West Ardnamurchan, and knows what he's looking for. He's an expert not only on wildlife but also in geology, to the extent that he runs courses for the Field Studies Council.
A selection of Martin's pictures will appear on the Diary over the next few days, starting with some of the sea creatures which he found in the rock pools along the coast below Trevor Potts' Ardnamurchan Campsite. The first, above, is a long-clawed porcelain crab, Pisidia longicornis. It's not surprising if people don't spot this character in our local rock pools - his carapace is only about 10mm across.
here, where a grim tale of parasitism, body snatching and chemical castration is told in horrid detail.
