Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 2. Lips of upper and lower jaws very darkly pigmented; a series of about five (indistinct posteriorly) brownish black saddle marks on the dorsal surface of the body, the first broad, starting before the first dorsal fin origin, the third smaller and paler than the others when viewed dorsally; ventral light organ small, lacking a dermal window; ventral surface of head and lower jaw almost entirely covered with small, heavily spinulated scales; snout moderately long 45.4-51.7% HL; mouth large, with upper jaw 26.0-33.3% HL; suborbital ridge not supported by continuous bone; buccal cavity black; fins pale dusky except for anal fin which has black pigmentation distally along anterior four-fifths (Ref. 26363).
Appears to form small schools (Ref. 26363).
