Short Description
Original Diagnosis after EBERT [22775]: Field Marks: Small sized sharks with cigar–shaped body, short, bulbous snout, suctorial lips, small, triangular–cusped lower teeth without blades and in 25 to 31 rows, spineless dorsal fins far posterior on back, no anal fin, nearly symmetrical caudal fin with long ventral lobe and a prominent dark collar–marking over branchial region. Diagnostic Features: Snout moderately short, about length of eye. Eyes anterior on head but sufficiently far back to lack an extensive anterior binocular field. Teeth in upper jaw 30 to 37, lower jaw 25 to 31; lowers moderately large. Interdorsal space over twice first dorsal–fin base, space between second dorsal–fin insertion and upper caudal–fin origin over twice second dorsal–fin base. Pectoral fins subquadrate, pelvic fins larger than dorsal fins. Second dorsal–fin height about equal to first. Caudal fin large and nearly symmetrical, with a long ventral caudal–fin lobe over 2/3 length of dorsal caudal–fin margin. Vertebral counts: total vertebral counts 81 to 89, precaudal vertebral counts 60 to 66, caudal vertebral counts 20 to 24. Intestinal valve turn counts 8 to 10. A small shark with a maximum total length of about 56 cm. Colour: pale brown above, becoming lighter below, with a conspicuous dark collar–like marking around the gill region; fins dark, but with pale to translucent edges.
