Description

Abstract A swimming, pelagic, giant (63.0mm SL) postlarva of Laeops nigro-maculatus was collected from the sea surface off the coast of Shirahama, Wakayama Prefecture, southern Japan. The postlarva is identified as a member of Laeops because it possesses such features as: an elongated second dorsal fin ray, dorsal and anal fins much elongated, an extra-ilial portion of the liver and intestine greatly produced from the abdominal cavity and supported by the posterior process of the pelvic bone, and no teeth in both jaws on the left side. The postlarva is iden-tified as Laeops nigromaculatus based on meristic features. This report represents the first description of a postlarva of this species based on a specimen in good con-dition. An earlier, incomplete description of a larval stage of this species was based on a badly-damaged specimen. Possibly the present postlarva was trans-ported into coastal waters due to strong onshore winds, and once arriving there succumbed to the effects of these colder, coastal waters.
