Blotched Tongue Sole

Juveniles use mangroves as nursery ground. Adults occur up to 140m depth on continental shelf; juveniles occur in turbid waters and prefer muddy bottom (Ref. 43081).

Dorsal spines (total): 0; Dorsal soft rays (total): 90 - 100; Analspines: 0; Analsoft rays: 72 - 78; Vertebrae: 44 - 49

Ocular side yellow-brown. Dorsal and anal fins joined to caudal. Eyes both on the left side of the body, a narrow space separating them; asymmetrical mouth; rostral hook below mouth. Ocular side with 2 lateral lines. Only the left ventral fin present (Ref 28). With very irregular dark brown blotches, often forming irregular cross bands. Some rays of dorsal and anal fins dashed with dark brown. Scales ctenoid on both sides of body. Midlateral-line scales 78 to 99. Scale rows between lateral lines on eyed side 15 to 19 (Ref 9895).

Found on the continental shelf over sandy and muddy bottoms. Occurs in the lower courses of flowing rivers and in estuaries (Ref. 12693, 48637). Feeds mostly on benthic invertebrates. Sold fresh, frozen, or dried salted in markets (Ref. 6806).

DESCRIPTION: Based on 87 specimens, 35.0–166.0 mm SL, including the paralectotype of C. brevis.

Depth of body 12.05–45.16 (M = 28.43), length of head 11.45–30.65 (M = 22.22) percent of standard length. Diameter of eye 6.25–16.13 (M = 10.71), interorbital space rather narrow, 0.36–6.67 (M = 3.03) percent of length of head. Two nostrils on ocular side, anterior nostrils tubular, in front of lower eye, posterior nostril simple, immediately in front of interorbital space. Snout rounded or obtusely pointed, 24.39–41.18 (M = 32.67) percent of length of head, rostral hook short, usually ends in front of anterior nostril, rarely reaching below anterior border of fixed eye. Maxillary extending to below middle or posterior half of fixed eye; angle of mouth extending to below vertical from anterior half or middle of fixed eye, usually nearer to tip of snout than to branchial opening; tip of snout to angle of mouth 34.21–51.43 (M = 44.16), angle of mouth to branchial opening 41.67–72.73 (M = 55.62) percent of length of head.

Scales: Ctenoid on both sides, including those of lateral lines.

Lateral-Line System: Two lateral lines on ocular side, dorsolateral line slightly undulating, running backward and entering dorsal fin along 5th–6th ray, counted from the rear, midlateral line with 78–99 (M = 87) scales, 14–19 (M = 16) scales between them. No lateral line on blind side.
