Abstract: | The pelagic larval stage of a pleuronectiform samarid, Plagiopsetta glossa, is described and illustrated, for the first time, from a 8.4-mm BL postflexion specimen collected off Tosa Bay, southern Japan. The larva is distinctive in having broad, semitransparent pterygiophore zones on the dorsal and anal fins, a trailing gut, flexible S-shaped pelvic bone, and a skin fold under the throat. These characteristics are shared with poecilopsettid larvae, suggesting a close relationship between the two families. |
