in the northern hemisphere. The family is well known as the subject
of a wide variety of biological studies. It includes at least 7 currently
recognized species. There is tremendous diversity in the sticklebacks
and taxonomy within the family is still debated. Our species, the Threespine
Stickleback, is a widely distributed and very variable species which
is generally less than 10 cm long. This species is most often found
in freshwater, but also enters brackish and coastal marine waters, occasionally
roaming far offshore. Spawning almost always takes place in freshwater.
Eggs usually develop within a nest built and guarded by the male. Threespine
Sticklebacks are frequently found in schools near the shore. They feed
on small crustaceans, insects, and small fishes. Larger fishes, seals,
and birds prey on sticklebacks. This fish is common in Puget Sound.
