Room 15 explored the tidal flats across the road from school and discovered all sorts of living creatures. There were whelks, chitons, limpets, worms, baby eels, snapping shrimp and many different kinds of crabs. Richard de Hamel came with us. He is a marine biologist. He gave us a chart so that we could identify different kinds of crabs. He taught us how to tell if they were male or female. Some of the female crabs had eggs. We put them back carefully where we found them.
