Sticklebacks are named for the spines found on their backs. They typically reach a size of 8 cm but may grow up to 18 cm. Sticklebacks are widespread in Canada and can be found in fresh, brackish, and saltwater. These small fish are an important part of the food chain as they act as a food source for larger fish and birds.
