📖 Overview

Food items are generally forcibly regurgitated by the fish's expunging gas bladder as it is hauled from the depths, but fish remains have been caught inside the mouth of a few individuals. Considered opportunistic feeders and will eat whatever animal food they encounter in the natural habitat as long as it is of appropriate size .
