These are mainly marine, tropical and temperate fishes characterized by a powerful sucking disk on the underside of the forebody.

[4] Skilletfish primarily feed on bristle worms and small crustaceans such as amphipods and isopods.

The female will lay a few hundred sticky, amber-colored eggs into an empty oyster shell, which the male will then protect until they hatch.

It can also be found in the Eastern Central Pacific: coastal lagoons and tidal flats of Sonora, Sinaloa and Nayarit, Mexico.

[3] The skillet ranges from New Jersey and New York in the northern end of its distribution south to Brazil, also occurring in the West Indies and the Gulf of Mexico.
