Morphology | Morphometrics
Most commonly found in surf around rocky headlands and along the shoreline, occasionally also in more still waters of river mouths. Very delicate and do not survive handling. Appear to be able to hybridize with congeners, Iso flosmaris and Iso hawaiiensis. Nothing else is known about this species. (Ref. 9769).
