The walleye has many long sharp teeth which helps it hold on to its prey. It eats small fish and other water animals like leeches and crayfish.

Walleye become fully grown in 5-6 years.  They may live for 16 years.

The walleye is a very tasty fish and they are often caught by fishermen. Besides people, walleye are eaten by otters, bald eagles, ospreys, and even snapping turtles. Walleye stay together in large groups called schools so they can warn each other about danger. If one fish spots danger they will all swim away quickly.

In spring, walleye move to where the lake or river bottom is covered in gravel. They spawn and the eggs fall into the spaces between the small stones, then the parents leave. Each female may lay thousands of eggs. The eggs hatch in 2 weeks and the young walleye swim off and feed on tiny water animals.
