Luzon Island, Philippines
Blennies are generally considered to be intertidal fishes; that is, they live in the zone consisting of only a few feet of water between high and low tide. Creatures that live in the intertidal zone must withstand greater variations in their surroundings, such as temperature, salinity, sunlight, and even wave action. Their turbulent environment may explain why blennies tend to be small (this one is about 1.5 inches long), live on the bottom, and seek the protection of holes, crevices, tubes, or depressions.
