Larvae and a juvenile of two tetragonurids, Tetragonurus cuvieri (8 specimens, 6.8-18.5 mm BL) and T.atlanticus (4 specimens, 6.0-10.9 mm BL), collected by larval net from waters off eastern Japan, represent the first records of such from the North-West Pacific. Both species possessed spines on the interopercle and subopercle in their early life stages, a juvenile (18.5 mm BL) of T.cuvieri having one spine on each element, and a postflexion larva (10.8 mm BL) of T.atlanticus having two interopercle spines and one subopercle spine.
