Eggs are attached on the nest wall and tended by the male parent (Ref. 56049). Eggs are deposited in a slightly flat single layer on both valves of mussel, attached to it by an adhesive disc. Egss have narrow perivitelline space; have granular yolk with clumped golden oil globules and clumped violet inclusion bodies both of which disperses, shrinks, and disappears with development; embryo in equatorial position, outline clearly visible on 3rd day; heart starts to beat at 7th day; eyes rotate and body twitches on 19th day; hatches after 21 days at 15.2-18.0 Celcius incubation (observations on the early life history of the mussel blenny by Stephens and Moser 1982, CalCoFl Rep., Vol XXIII, pp. 269-275, full text available online but not yet in FB). Field collected egg diameters (0.69-0.8 mm) reported from the said reference.
