Three-spined Stickleback

stickbak.jpg (8332 bytes) Sticklebacks are small silvery fish which are usually about 4-6 cm long. They live in freshwater, although they can also be found in salty water where rivers meet the sea. They live in both running and still water habitats.

In the breeding season, the males have a bright red breast. They are territorial and guard the nest in which the females lay the eggs.

Sticklebacks are carnivores, eating small aquatic animals. The spines on the back of the fish can be raised to help deter predators such as larger fish, from eating them.
