The opposite direction of the water it moved.
The squid uses its siphon to propel itself through the water.
jet population
If the victim expels the object or becomes unconscious.
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.
Possibly water resistance (drag)
A squid swims backwards because this direction makes it easiest to move in the water since its arms and head are on the front of their bodies. The squid can actually swim in any direction it chooses.
The downward force of gravity is counterbalanced by the upward buoyant force of the water, resulting in a net decrease of the body's weight. The buoyant force comes from the water that is displaced by the body (think of water rising in the tub when you get in). That displaced water tries to get back to its own (previous) level, so it pushes back on the body.
Squids do not have backbones.
They cannot live in warm water. They do not have back bones. There is two facts -- Bobtail squid, and in fact many other species, live in warm water. They have 8 arms and 2 tentacles, have chromatophores which let them change their colour, and have large eyes that are adapted for low-light situations and quite advanced. --
The Colossal Squid = back then the holder for the title of having the largest eyes but now the colossal squid snatches the title .The eye is 27 cm (10.63 in) wide, with a lens 12 cm across. Probobly the Colossal Squid but they have not found hard evidence that they exist, so I saying that the title is the Giant Squid.
If you get feces in a wound or if you eat it you could get extremely sick, your body expels this waste for a reason don't go putting it back into your system.
Well, it is complicated, the trapped gas uses the force of pressure against the underlying water with the same amount of force that the water is putting on the gas. So the water doesn't go in the cup because the air is pushing it back.
I guess you could consider it both. A squid can kill with their ink but other ocean animals could react back and kill it.
The two longer tentacles on a squid serve as feeding arms, they shoot them out simutaniously to grip their prey and bring it back to the mouth.
