　　29 Television Day: Life on the sea-shore
Today our TV cameras visit a rocky sea-shore. The tide is out at the moment. You can see the sea-bed and there are tiny rock-pools everywhere. With its crabs¹, shrimps², fish and shell-fish, a rock-pool is a busy place-even if it looks quiet and empty. There are limpets in the rocks. They look like snails³. When the tide comes in or goes out, it won't wash them away because they cling tightly to the rocks. Some sea-creatures, like clams⁴ and cockles, can't cling to the rocks to avoid the pull of the tide.They have to dig into the sand. Notice the sea-gulls beside the pools. They always arrive the moment the tide goes out. They know there is plenty to eat in the pools. The sea comes and goes twice a day, but it never takes the sea-creatures by surprise. It doesn't disturb their lives. All the creatures by the shore live in special places. If you visit the same rock-pool several times, you will get to know its inhabitants- but you must be very very patient!
