The neon flying squid (Ommastrephes bartramii) is a remarkable cephalopod that can launch itself from the ocean and glide through the air in formation, a behavior that has fascinated scientists and sailors alike. This extraordinary ability, once dismissed as sailor folklore, was finally documented by Japanese researchers in 2013, capturing the world's attention with photographs of a shoal of about 100 squid soaring above the Pacific Ocean.
What Makes the Neon Flying Squid Unique?
The neon flying squid belongs to a family of about 20 species known for their aerial prowess. Unlike other squid that merely leap from the water, the neon flying squid uses a specialized organ called the hyponome—a funnel-like muscular structure that jets water to propel itself both underwater and through the air. This propulsion system allows the squid to achieve elevation and glide for distances up to 30 meters, with their arms splayed outward like wings.

Physical Characteristics and Habitat
Neon flying squid are roughly the size of a rolling pin, measuring about 30-40 centimeters in length. They are found in temperate and tropical oceans worldwide, often gathering near the surface to feed on fish and crustaceans. Their name derives from the bioluminescent photophores that emit a soft glow, adding to their alien-like appearance.
Why Do Flying Squid Glide in Formation?
While the exact reason for their synchronized flight remains unclear, scientists hypothesize that it may be an evasive maneuver to escape predators such as sharks or mahi mahi. The behavior could also be a form of energy-efficient travel, allowing the squid to cover greater distances with less effort. Dr. William Gilly, a Stanford University biologist, notes that while he has seen individual squid leap to escape predators, witnessing group gliding is extremely rare and requires a stroke of luck.
Comparing Flying Squid to Other Gliding Marine Animals
To better understand this phenomenon, let's compare the neon flying squid with other gliding marine species:
| Species | Gliding Mechanism | Max Glide Distance | Social Gliding |
|---|---|---|---|
| Neon Flying Squid | Hyponome jet propulsion | ~30 meters | Yes (formation) |
| Flying Fish | Enlarged pectoral fins | ~200 meters | Yes (schools) |
| Humboldt Squid | Jet propulsion (limited) | ~2 meters | No (solo leaps) |
Key Takeaways About Neon Flying Squid
- Neon flying squid can glide up to 30 meters above the ocean surface.
- They use the hyponome, a muscular funnel, for jet propulsion in water and air.
- Formation flying is rare and may serve as predator evasion.
- These squid are found worldwide in temperate and tropical seas.
- Their bioluminescence adds to their mysterious, alien-like appearance.
Frequently Asked Questions
FAQ
Can neon flying squid actually fly?
Yes, neon flying squid can glide above the water for distances up to 30 meters, using jet propulsion from their hyponome to gain elevation and then spreading their arms to maintain lift.
Why do flying squid leap out of the water?
The primary reason is likely to evade predators, such as sharks or larger fish. It may also be a method of efficient travel, though this is still under investigation.
Are neon flying squid dangerous to humans?
No, neon flying squid are not dangerous to humans. They are small, shy creatures that avoid contact. However, they may occasionally land on boats, but they pose no threat.
Understanding the neon flying squid's aerial behavior not only sheds light on the incredible adaptability of cephalopods but also reminds us of the many mysteries that still lurk beneath the ocean's surface. Whether you're a marine biology enthusiast or simply curious about nature's wonders, the neon flying squid is a testament to the unexpected marvels of the deep sea.
