Rocket Principle of Giant Squid in Deep seas

Certain creatures found in nature employing this rocketry principle of ejecting mass stored in their bodies to create movement, best example shall be a Giant Squid in deep seas.

The Giant Squid is a large creature about 10 to 14 m long and is found in the deep oceans.A few have been caught off the coast or have been washed ashore the New Zealand coast. 

The Giant squid moves in the deep seas by taking the water in by expanding its antle. It holds the water and pressurizes it to about 40 kpa by contracting its mantle.The pressurized water and any other matter that it has gulped, such as,fish,eggs, etc., is squeezed out through a opening ,known as the funnel that can rotate in any direction.The gradual impulse from the squirting out of the water and waste pushes it by as much as 50 m for a single squirt.It is estimated to achieve a velocity of about 7 m/s in a single push of the water and waste.A schematic diag
