Discussion Microgobius gulosus has the most compressed otoliths known so far from extant species in the genus, with an OL:OH ratio of 0.95–0.97, caused primarily by the rather low dorsal rim, and a relatively small sulcus (OL:SuL = 1.65–1.85). Two well-preserved specimens from the Late Pliocene of Atlantic Panama are reported south of the southernmost extant occurrence, which according to Froese and Pauly (2023) is the Yucatan Peninsula of Mexico. Microgobius gulosus is known to commonly live in burrows ( Birdsong, 1981).
