A squid's funnel acts just like a jet engine, generating them strong swimmers. It attracts drinking water into its mantle cavity by expanding its muscles. The mantle stretches similar to a rubber band, then contracts and forcibly pushes the drinking water out with the funnel. The squid shoots backward, tail initial. When escaping from the predator, a squid can propel itself as rapidly as 25 body lengths a next. With their delicate bodies, squid are vulnerable prey.
