Beckley, L.E. (1989) Larval development of Spondyliosoma emarginatum (Cuvier and Valenciennes) (Pisces: Sparidae) from southern Africa. South African Journal of Zoology, 24 (3). pp. 187-192.

Abstract

The larval development of the southern African endemic sparid Spondyliosoma emarginatum is described and illustrated from specimens collected in Algoa Bay and the Swartkops, Sundays and Swartvlei estuaries of the Cape Province. S. emarginatum has demersal eggs. Preflexion larvae are moderately elongate with body depth increasing to 31% BL in postflexion stages. The head is rounded and the snout blunt but becomes more elongate in postflexion stages. There are short spines on the preoperculum. Osteological development is described from a series of cleared and stained specimens. The larvae of S. emarginatum are compared with those of the European S. canthurus and other southern African sparids
