15 Fin-tastic Facts About Horse-Eye Jack For Kids

Horse eye jack facts are fascinating to all marine enthusiasts irrespective of their age.

In the 19th century, a Swiss naturalist, Louis Agassiz documented the horse eye jack (Caranx latus) based on the collected specimen from a marine body near Brazil. Widely popular as a game fish, anglers are often after the horse eye jack. The horse eye derives its name from its large, developed eyes that have become the primary characteristic for their identification. The bigeye trevally (Caranx sexfasciatus) and the crevalle jack (Caranx hippos) have often been confused with one another. Scientists also considered the horse eye as a form of the bigeye but that theory has been debunked. Marine enthusiasts are fascinated by the dark blue, oblong body, blunt head, soft dorsal fin, and anal fins of this species.

Due to its availability in the Atlantic, the International Union for Conservation of Nature (IUCN) Red List of Threatened Species lists it as a species of Least Concern. However, it is also true that this offshore fish is extensively subjected to recreational pleasure and this might become a concerning issue.
