Jack Crevalle is a pelagic species found in both oceans but is considered a different species in the
Atlantic (Caranx hippos) . Crevalle Jacks are pugnacious-looking fish which live up to those looks. A dark
spot on the gill cover and steeply convex forehead separate this species from other jackfish. Strong
bony scutes on the tail are common to all jacks. Crevalle jacks can be poisonous to eat due to the threat
of ciguatera poisoning, but they are prized as a game fish.

A number of species of Jacks are found in the inshore waters on the Pacific coast of Costa Rica. I caught the Crevalle on the left while surfcasting off the beach in Playa Jaco. We also regularly catch Jacks while trolling inshore bays and rocky headlands near Los Suenos Marina.
