Fish fin

Fish have fins that help them swim through the water. Fins are like little arms or legs that they use to move around.

A fish's main fins are the dorsal fin (on their back), the anal fin (on their belly), and the caudal fin (on their tail). These fins help the fish move forward and change direction.

The pectoral fins (on their sides) are like tiny hands that they use to steer and turn. Think of them like paddles that help the fish move left or right.

The pelvic fins (also on their belly) are used to stabilize the fish and keep them from tipping over. They help the fish stay upright in the water.

Overall, fish fins are really important for their survival. They help them swim, catch prey, and avoid predators. Different types of fish have different fin shapes and sizes depending on their habitats and lifestyles.
