Found in open waters but also near the coast (Ref. 9293, 11230). Forms schools. Piscivore (Ref. 39061, 46174). An analysis of stomach contents (Ref. 6859) suggests that feeding is round the clock. Dolphins tend to be closely associated with Sargassum communities as well as with floating and drifting objects on the high seas. In eastern Caribbean, diet varies with season, and mysids are a very important component from October to December (Ref. 39061). Diet also varies slightly with predator size (small dolphinfish eat fewer flyingfish and more squid than larger sized dolphinfish), and with sex (males take proportionally more of the active fast swimming species such as flyingfish, squid and dolphinfish than do females) (Ref. 39061). Pelagic-oceanic. Inhabits coastal waters. Either in pairs or forms small shoals below flotsam. Migratory pattern influenced by temperature, where it follows warm water currents. Feeds on small fishes, squids and crustaceans (Ref. 9773). |
