Squid swim like?

Surely you will be surprised when you hear: For many creatures, the wild method 'grab your hair to lift yourself up' is their usual way of moving in the water. So is the ink.

The ink and the majority of the first-class molluscs move in the water in the same way: taking water into the trough through the side slit and a special funnel in front of the body, then they use water jet through that funnel. Thus, according to the counterproductive law, they receive an opposite repulsion enough for their bodies to swim quite quickly forward. In addition, the ink can rotate the funnel to one side or backward and when pressed to push the water out of the funnel, it can move in any direction.

The jellyfish's movement is similar: it shrinks the muscles to push water from its bell-shaped body and it is pushed backwards. The motion of water beetles, dragonfly larvae and many other aquatic animals follow the same method.
