Fish comes in an
amazing variety of shapes and colours. All of it live in water, have fins, and
use gills to get oxygen from the water. Fish take in water all
the time. The water flows in through the mouth, over the gills, and out through
the sides of the head. When a fish takes in water, it is not drinking but
breathing, and the gills absorb oxygen from the water. The body of a fish is
made up of the head, the trunk, and the tail fins.
