LOPEZ MARTINEZ, Juana  y  RODRIGUEZ ROMERO, Jesús. First record of association of the Blackfin Jack Hemicaranx zelotes Gilbert (Pisces: Carangidae) with the cannonball jellyfish Stomolophus meleagris Agassiz (Scyphozoa: Rhizostomatidae) in Kino Bay, Gulf of California. Hidrobiológica [online]. 2008, vol.18, n.2, pp.173-176. ISSN 0188-8897.

Juvenile Blacking Jack Hemicaranx zelotes (Gilbert 1898) associated with cannonball jellies Stomolophus meleagris (Agassiz 1860) in Kino Bay, Gulf of California, Mexico was observed. The fish accompany the jellies, swim between the umbrella and the oral arms, showing a symbiotic behavior that the fish use for protection from predators. This is the first record of a symbiotic association of Blacking Jack with can-nonball jellies.
