An account of the eggs and developmental stages of montagu's blenny, coryphoblennius galerita (l.), with notes on the reproductive behaviour of the adults

Montagu's blenny, Coryphoblennius galerita was reared to late larval stage under laboratory conditions. The adult male guarded the eggs and aerated them with its tail during the incubation period. The larvae had a small amount of yolk on hatching and although they appeared to be feeding on the variety of food introduced, no food was observed in the gut. The gas bladder, observable above the gut in all larvae, was filled with gas only in the one specimen, killed at 45 mm t.l., which survived after the yolk was utilized, and in some 4 mm specimens taken from the plankton off Mweenish. Descriptions are given of the larval stages and of juveniles taken from rock pools.
