They were always slow children. You would think that, with six legs apiece and three joints in each leg, they might walk quite fast, yet they never did. When they had to, they hurried in another way by taking a long leap through the water. Of course they breathed water like their neighbors, the fishes and the Tadpoles. They did not breathe it into their mouths, or through gills, but took it in through some openings in the back part of their bodies. When they wanted to hurry, they breathed this water out so suddenly that it sent them quickly ahead.
