The neon flying squid is a remarkable cephalopod that can launch itself from the ocean and glide in formation, a behavior that has fascinated scientists and sailors alike. This extraordinary ability, once dismissed as myth, was finally documented by Japanese researchers in 2013, revealing a spectacle that resembles an alien invasion.
The Science Behind Squid Flight
Neon flying squid (Ommastrephes bartramii) use a muscular organ called the hyponome to propel themselves through the water. This funnel-like structure expels water with incredible force, allowing the squid to jet both underwater and, when aimed upward, to break the surface and become airborne. Once in the air, they spread their ten arms to create lift, much like wings, enabling them to glide for distances of up to 30 meters.

Researchers observed a shoal of about 100 neon flying squid gliding in unison near a research vessel in the Pacific Ocean, about 370 miles from Tokyo. The coordinated flight lasted for several seconds, with the squid maintaining a synchronized formation. This behavior is thought to be an escape mechanism from predators such as sharks, though the exact trigger remains unknown.
Comparison with Other Cephalopods
While many cephalopods can jet through water, only a few species are known to fly. The table below highlights key differences between the neon flying squid and other related species.
| Species | Flying Ability | Typical Size | Habitat |
|---|---|---|---|
| Neon Flying Squid | Yes, glides in formation | ~30 cm | Open ocean |
| Humboldt Squid | Occasional leaps | ~1.5 m | Eastern Pacific |
| Common Octopus | No | ~60 cm | Coastal waters |
Why Do They Fly?
The primary reason for flying is likely predator evasion. By launching into the air, squid can escape fast-moving fish like mahi mahi, which have been observed leaping out of the water to catch them mid-flight. Stanford biologist William Gilly, who has studied squid for decades, notes that while he has seen individual leaps, group gliding is exceptionally rare and requires a stroke of luck to witness.
Another theory suggests that flying helps squid cover large distances efficiently, conserving energy during migration. However, more research is needed to fully understand this behavior.
Key Takeaways
- Neon flying squid can glide up to 30 meters above the ocean surface.
- They use jet propulsion via the hyponome to launch themselves.
- Group gliding is a rare, coordinated behavior likely used for predator evasion.
- These squid are found worldwide and sometimes land on boats.
