Aerial locomotion in marine animals
Jet propulsion generates thrust and momentum by shooting out water jets. Flying squid is known for their behavior of leaping out of the water. Ommastrephinae and Todarodinae are two subfamilies of squids under the family of Ommastrephidae. They utilize jet propulsion to jump out of water as they do underwater, including Japanese flying squid.., Humboldt squid, Neon flying squid, sevenstar flying squid, and Wellington flying squid. Squid flight may be thought to reduce the cost of migration. The acceleration of Sthenoteuthis pteropus in air is 265 body lengths/s (24.5 m/s), which is found to exceed that in water (79 body lengths/s).
