Flying Squid Species in mid-air, roughly 100 nm North of Tristan Da Cunha, South Atlantic Ocean. Flying Squid use membranes between their tentacles (visible on pic) & two fins at the rear of the mantle to glide through the air in a similar way to flying fish.

Flying Squid Species in mid-air (Ommastrephes bartramii). Extremely rare unusual image. South Atlantic Ocean. MORE INFO: Flying Squid use membranes between their tentacles (visible on pic) & two fins at the rear of the mantle to glide through the air in a similar way to flying fish. These unique adaptations allow them to avoid predation more easily. Ommastrephid squids are among the strongest swimmers in the Cephalopoda. A number of species are fished commercially. This particular species (Ommastrephes bartramii), is commonly known as "Neon Flying Squid" due to its colouration and its ability to glide over the ocean surface as seen in the photographs. Please note that this is a genuine image of a wild animal in its natural environment. It is not a digital manipulation.
