Blennioids with three partitioned dorsal fins, these small (most are just a
few cm. long) fishes live on the bottom. If you look closely the 20 some genera,
200 some species can be further distinguished from the similar gobies by the
position of scales, more pointed snouts and how they perch... on their narrow
ventral fins rather than a "goby disc".
