the squid uses jet propulsion to get around the ocean. that is how it moves.
squid just swim
the shape of the squid helps it to gild through the water quickly.
Something that allows a squid to shoot throughly the water.
To make the fish swim.
Fish have a stream line body shape to help the glide through the water easier with more speed.
Squid use a kind of jet power. Water is squirted at great pressure out of a nozzle on the squid's body. At times the squid can swim so fast that it may pop out of the water and glide through the air at 25 to 40 miles per hour. A squid may fly for 100 feet or more before it splashes back into the water.
Fish have a stream line body shape to help the glide through the water easier with more speed.
A boat's shape is usually more streamlines on the bottom, the faster the boat the more streamlined it will be, this allows the vessel to cut through the water much like a knife.
The shape of a perch's stomach helps it to digest its food easily. It's shape also helps it to swim effortlessly through the water.
Water is important in the plants shape as the pressure from the water in the cells help to keep the plants shape. When a plant is devoid of water it begins to droop, this means there is no water in the cells to help keep it upright.
the gills help the squid breathe
The squid has a special "engine" that runs on oil from the ocean floor and comes out when the squid wants to move. With this it is able to move at speeds up to 115mph.
It gives them hydrodynamics so that the can "cut" through the water and move faster than, say, a parachute would.
