Otolith description

Otolith small to medium, ovate. Features vary considerably with ontogeny. Dorsal margin lobed in smaller specimens to entire in larger ones; ventral margin sinuate in smaller specimens to acutely dentate in larger. Sulcus groove heterosulcoid and curved ventrally at posterior end, opening ostial. Ostium and cauda well developed. Colliculum heteromorph; anterior colliculum wider than posterior colliculum. Collum absent. Crista superior ridge-like; crista inferior ridge-like except beneath ostium where it is indistinct. Rostrum broad, short and rounded in small otoliths, but broad, short and pointed in large otoliths. Antirostrum rounded in smaller specimens and pointed in larger. Excisura becomes deeper with a more acute angle as individuals increase in size, being groove-like in larger specimens. Dorsal area depression develops with growth, becoming deep above cauda.
