Task 6
The professor talks about how snails survive in hot and dry climate. First, in the hot climate, snails would find shelter of vegetation, so they can get out of the sun and into the shades. The ground is hot in the sun because it absorbs and radiates heat. Snails can attach themselves to a wall or a tree since it’s cooler. Second, in the dry climate, snails secret a sticky slimy substance that’s made of calcium and use it to cover the opening of the shell. Snails stay inside for a long time, and their bodies slow down, so they don’t need much food. They survive on the previously stored food. When it rains again, they will open the shell.
