Look closely in the photo with boats in the background: see all those red dots? People used to deciduous trees whose leaves turn red and fall to the ground each autumn many instinctively think: fallen leaves! But no: these are sand crabs, bright red and with protruberant eyes which I’ve never yet succeeded in photographing. I’d need a far better telescopic lens than comes with the pocket digi-cam I carry with me on these beach walks. They evade large moving objects rapidly, by disappearing down holes which dot the beach, like the one you see above to, right. Top left, and below: we think this guy was sick and lost: he was still able to scuttle, but slower than usual, and seemed to have become separated from his burrow. I suspect he ended up like one of these other ex-crabs I’m showing you above. As the Lion King’s song says: Circle of Life, eh?
