Labrisomids are small blennioids (blennies), percomorph marine fish belonging to the family Labrisomidae.

[1] Generally staying within shallow coastal regions to depths around 10 m, labrisomids are benthic fish spending most of their time on or near the bottom.

Crustaceans, gastropods, brittle stars, and sea urchins make up much of the labrisomid diet.

[1] Two genera of labrisomid are noted for their ovoviviparity; Xenomedea and Starksia both retain eggs within their oviducts, where they develop in safety.

However, only Starksia species possess gonopodia (modified anal fins used as a copulatory organ).
