This species is characterized by the following: usual number of vertebrae, precaudal 16 (14-17), caudal 60-62 (59-64), total 76-78 (75-80); fin rays, dorsal 138-146 (134-148), anal 117-120 (111-123) pectoral 23-24 (21-25); pyloric caeca 4-5 (3-6), usually 3-4 in one whorl, 1-2 in second tier, sometimes 1 in a third tier; first gill arch with rudimentary rakers 3 (2-4) on the upper arm, 4 (sometimes 5) developed but short rakers on lower arm, rudiments anterior on the first arch vary from 1-10 (usually 5-8); total rakers 12-16 (9-18) with most of the variations due to the rudiments; dorsal-fin origin between neural spines 4-5 (26 specimens) or 3-4 (17 specimens) (Ref.
91765
).
Common species (Ref.
34024
). Adults inhabit soft bottoms, from shallow waters to moderate depths (Ref.
