Can Squids Fly?

Caribbean reef squids can jump out of the water and fly up to 30 feet (10 meters), which is about 50 times their body length. The Caribbean reef isn't the only squid that can fly though — there are at least six species of squid that have been seen flying. Scientists think that they use the same methods of propulsion for flying through the air as they do for gliding through the water.

More facts about squids:

  • The heaviest squid ever found weighed over 1,000 pounds (about 450 kg).

  • Squids have sharply serrated radula (an organ similar to a tongue), which cut up food before it reaches their stomach.

  • Besides expelling inky liquid (called sepia) to escape from attackers, squids can also change their skin color and texture to blend in with their surroundings.

Frequently Asked Questions

Can squids really fly?

Yes, certain species of squid can indeed 'fly.' These squids propel themselves out of the water by expelling water from their funnel-like siphons, launching into the air. Once airborne, they spread their fins and tentacles to glide over the surface, covering distances up to 30 meters. This behavior is thought to be a means of escaping predators or traveling quickly.

How do squids achieve flight?

Squids achieve flight by building up water pressure in their mantle cavity and then forcefully ejecting it through their siphon, propelling themselves out of the water. In the air, they spread out their fins and tentacles to create aerodynamic surfaces, which allows them to glide. Researchers have observed that they can reach speeds of up to 11.2 meters per second during these flights.

Which species of squid are known to 'fly'?

The most well-known species that exhibit this flying behavior are from the genus Ommastrephes, such as the Japanese flying squid (Todarodes pacificus). Observations and studies have documented their ability to launch themselves out of the water and glide for considerable distances, an adaptation that aids in their survival and mobility.

Why do squids engage in this flying behavior?

Squids engage in flying primarily to escape from predators, such as larger fish, dolphins, and seabirds. The aerial maneuver can be a quicker mode of travel than swimming, allowing squids to rapidly put distance between themselves and threats. Additionally, it may be used for migration or to save energy during long-distance travel.

How long can squids remain airborne?

Squids can remain airborne for several seconds and cover distances up to 30 meters. The duration and distance of their flight depend on factors such as the squid's size, the angle of launch, and environmental conditions like wind and air humidity. Their gliding ability is quite remarkable for creatures that are not traditionally adapted for flight.

Is the flying behavior of squids well-documented by science?

The flying behavior of squids is increasingly well-documented, with numerous eyewitness accounts and scientific studies confirming the phenomenon. Researchers have used photography and video analysis to study the mechanics of squid flight, contributing to our understanding of this extraordinary adaptation. Despite this, there is still much to learn about the nuances of their aerial abilities.
