bigeye

Any fish in the taxonomic family Priacanthidae, which have large eyes.

Any of certain fish or shark species identified by their large eyes, in particular bigeye tuna, Thunnus obesus.

There were Port Jackson sharks with a brown back, a whitish belly, and eleven rows of teeth, bigeye sharks with necks marked by a large black spot encircled in white and resembling an eye, and Isabella sharks whose rounded snouts were strewn with dark speckles.

The relatively large eyes may enable the bigeye to feed at lower light intensity than other tunas.
