Other than some beach glass or broken shells, the best thing to take from a tide pool is a photograph.
We always see the little hermit crabs.Hermit crabs don't make their own shells, you know. They take advantage of abandoned shells, mostly those of the sea snails, and move in. As they grow they crawl out of these shells and move into larger digs. I've read that certain species of hermit crabs will form what is known as "vacancy chains". A group of crabs will surround a vacant shell. They'll line themselves up from largest to smallest and once the largest crab fits himself into the shell the next largest crab fits himself into the newly vacated shell and so on to the smallest crab in line. Hermit crabs aide in keeping the water nice and clean and clear by scavenging dead animal and plant materials. Not much goes to waste. The fact that they don't make their own shells is one good reason to limit the collection of intact shells.
This year we actually haven't had as much fog as usual, so far. We even had a rainstorm the other day which is pretty much unheard of after the beginning of May. So, it leaves me wondering if this is an unusual weather event, or further evidence of climate change? In bocca al lupo. m & v
