Ornithoteuthis antillarum, the Atlantic bird squid, is a species of flying squid from the family Ommastrephidae which is found in the warmer waters of the Atlantic Ocean. This species is an important component of the diet of many species of fish and of cetaceans.

Ornithoteuthis antillarumAdam, 1957 is a com- mon nektonic squid inhabiting epipelagic and mesopelagic waters of the tropical Atlantic from the Carribbean Sea to the continental slope of Angola (Nesis, 1987).

One species, Ornithoteuthis antillarum, is found in the warmer waters of the Atlantic Ocean and the other, Ornithoteuthis volatilis, in similar areas of the Indo-Pacific oceans, they are closely related and are thought to have been a result of relatively recent speciation.
