Two types of pelagic larvae of bembrops (trachinoidea: percophidae), with notes on their phylogenetic implication

摘要

A larva and a pelagic juvenile of Bembrops curvatura are identified and described from Japanese water. These pelagic larvae are remarkable in developing a transparent enlarged Dermal space over the head, i.e., so-called "bubblemorph," which disappears by 15.8 mm SL Through metamorphosis. Pigmentation is scant, but a peritoneal pigment section over the gut Is distinct. Occurrence of a similar larva of Bembrops in Australian waters probably referable To another species is also recorded, although its specific identification cannot be made.
