How do squids jet through the water so fast?

Quick Answer

Squids move by taking in water and forcing it out through a funnel called a siphon. The jet-like thrust can propel them quickly in short bursts.

The Full Story

Squids swim using jet propulsion. They draw water into the mantle cavity and then contract muscles to shoot it out through a narrow siphon. By aiming the siphon, they can steer and accelerate in different directions. This works especially well for sudden escapes from predators. Some species also use fins for slower, more efficient cruising, but jetting is their famous burst-speed system.
