Triplefins
Triplefins are found on temperate and tropical reefs in most parts of the world, where they are generally inconspicuous small fish. The blue-dot triplefin (Notoclinops caerulepunctus), here photographed on a rock wall at the Poor Knights Islands, is, at 5 cm, one of the smallest of the 26 species of triplefin found in New Zealand waters.
