Let’s see if you can fin-ish this puzzle. Here are the names of the five main fins found on most fish, as well as a description of how they are used. Can you match the names with their descriptions and the arrows on the fish diagram?

Anal

Caudal

Dorsal

Pectoral

Pelvic

1. This fin, which is found near the back of a fish on its underbelly, works with the “Arrow A” fin to help a fish keep its balance. Some species use this fin while spawning.

2. If a fish were a land animal, this pair of fins would be its legs. They help the fish control the direction that it is moving. They also work with the “Arrow E” fins when the fish needs to suddenly stop.

3. This fin, which is sometimes called a tail fin, makes wave-like motions that propel a fish through the water. Often, the shape of this fin provides a clue to how fast the fish can swim. A forked, or crescent-shaped fin is usually found on a fast swimmer. Generally, the rounder this fin is, the slower the fish is.

4. Sometimes, this fin is divided into two separate fins along top of the fish. It works with the “Arrow C” fin to help keep the fish upright.

5. This pair of fins, if the fish were a land animal, would be its arms or front legs. They help to spin a fish around on its axis. When a fish sticks them out at the same time, they serve as a brake. These fins also help the fish move up and down. Some fish use these fins to stir up food from the bottom or to gently fan water over their eggs.
