A shipon is like a filter it washes water in a out (like gills) for the airway. The siphon also helps the squid move faster.
the part of a squid's brain that controls the muscle siphon
a siphon is an organ through which water is sucked in and out, either for filter-feeding or to produce oxygen. Also, it helps the squid move.
Waste exits a squid by being transported through the anus and out of the siphon.
This a very simple answer. They use their tentacles to push themselves through the water. No this is actually wrong. The squid uses its siphon to propel itself through the water. How it does this is it fills its mantle with water then the squid pushes it out through the Siphon.
Squid respire via the mantle; water is pulled in, pushed across the gills, and then expelled via the exhalent siphon of the mantle.
Siphon
The squid sucks up water a tube called the siphon, then shoots it out to provide locomotion by jet propulsion.
The squid has a muscular mantle (outer covering) which, when expanded, fills with water. When these muscles contract, water is expelled through a single siphon and the squid is propelled in the opposite direction. The squid can control its direction by rotating (moving) the siphon.
The opposite direction of the water it moved.
Siphons can be used as a form of locomotion. Water goes into the siphon and shoots out and acts as a form of jet propulsion, directing the squid in the way it wants to go.
Two defense mechanisms squid use is their ink sac, and also their ability to camouflage. Squid can also move really quickly through their siphon, and jet propulsion.
A siphon is found in octopus, squid, and in some snails and clams. The function is movement, feeding, respiration, and reproduction. In bi-valves, the siphons are paired. In cephalopods, there is a single siphon or funnel which is known as a hyponome.
