The Blenny Family is commonly confused with the Goby family. The Blennies are distinguished by their single continuous dorsal fin and habit of resting on the bottom with their body curved. These fish will usually have tiny appendages on the top of their heads called "cirri". Some Blennies inhabit tidal pools where the water is warm and shallow. They have incredible jumping ability and are known to jump from pool to pool, which lends to the other name they are known as: "Rock Skipper". Other Blennies are found hiding in crevices and caves at coral reefs. These fish have blunt heads and their teeth are combed, giving them the ability to scrape algae -- their primary food source -- from rock surfaces.
