A silverfish is a tiny insect that lives in houses, not in water. It is long and flat, with a body that looks a bit silver or grey, like fish scales, and it has no wings, so it cannot fly. It runs with a quick wriggle, which is why people thought of a little fish. You find it in bathrooms, kitchens, cupboards, and old books — quiet, slightly damp places. It eats paper, glue, and crumbs. It does not bite people, but it can spoil books and clothes. The name is the ordinary English word, not a science-class word. One or many, people often still say silverfish.
