The fish known collectively as “stickleback
species pairs” are small,
freshwater fish which are of particular
scientific interest because of their
evolutionary history and their extremely
limited distribution. They are
descended from the ocean-dwelling
Threespine Stickleback, which is
common in coastal marine waters
throughout the Northern Hemisphere.
Populations of freshwater sticklebacks
are often found in low-elevation coastal
lakes and streams, but it is only in a very
few locations that marine sticklebacks
have evolved into species pairs – two
distinct but closely related species living
side-by-side in the same lake.
