Heteropriacanthus, the glasseyes or glass bigeyes, are a genus of the bigeye family found in all tropical seas around the world.

It occasionally makes its way into the aquarium trade.

It grows to a size of 50.7 cm (20.0 in) in total length.

[2][3][4] The glasseyes has been classified in a single species, Heteropriacanthus cruentatus,[5] but recent morphological and genetic analysis indicates that glasseyes may be better divided into three species: Heteropriacanthus cruentatus (Atlantic Ocean and southwest Indian Ocean), H. fulgens (northeastern Atlantic), and H. carolinus (Indo-Pacific).

[6] H.cruentatus can differentiated from the rest of its genus by looking at its caudal and anal fin in which is distinct in colour.
