Hypleurochilus langi (Fowler, 1923)

Description


Dorsal spines (total): 12; Dorsal soft rays (total): 14 - 17; Anal spines: 2; Anal soft rays: 16 - 19. Diagnosis: length of supraorbital tentacles varies from approximately 2/3 of eye diameter to 2 times this diameter; longest tentacles occur in male specimens; shape of supraorbital tentacles varies from a single finger-like appendage bearing 2-4 filaments at the rear base to 4 appendages of almost equal length; anterior nostril forms a small tube which bears up to 4 cirri on posterior rim, only 1 in most cases; only one ring of cephalic sensory pores in infraorbital and preopercular series; lateral line does not reach beyond level of 8th-10th spine of dorsal fin; both males and females with a thin crest on head, but crest in females not as high as in males; dorsal fin with 12 spines and 14-17, generally 15-16, soft rays, last spine shorter than soft rays; anal fin with 2 spines and 16-19, generally 17-18, soft rays; caudal fin rounded (Ref. 81288). Coloration: in alcohol, uniformly clear brown, lower part of head and throat clearer; some individuals with a black spot on membrane between 1st and 3rd dorsal spines; sometimes flanks bearing vertical stripes darker (Ref. 81288).

    Biology


    Euryhaline, entering mouth of large rivers and mangroves, but always in brackish water (Ref. 81288). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Maximum SL recorded was 7.0 cm (Ref. 4342).
