📖 Overview

Inhabits the outer continental shelf . Known only from the holotype. The presence of a very thin-walled, large egg-case in each uterus of the holotype suggests that the species may be ovoviviparous, and presumably have had two young in a litter . Experts classify this species as oviparous . Its large mouth, small teeth, and large pharynx with gillraker papillae might allow it to feed on very small invertebrates, according to S. Springer.
