Siphon (mollusc) - Wikipedia
A siphon is an anatomical structure which is part of the body of aquatic molluscs in three classes: Gastropoda, Bivalvia and Cephalopoda (members of these classes include saltwater and freshwater snails, clams, octopus, squid and relatives).
Locomotion - Gilly Lab
The siphon is very flexible, and it can aim in any direction underneath the squid, so the animal can travel arms-first, upward (to generate lift), downward, or at any angle in between. Because the jet can be very powerful, jetting is a great way to accelerate and swim quickly.
The body of the colossal squid - Te Papa
The funnel, or siphon, is a muscular structure located on the ventral surface of the mantle. It has several functions, including respiration and discharge of wastes. The colossal squid also uses the funnel to help it move in the water.
Jet Propulsion Locomotion Of Squid And Octopus - Science Friday
2015年6月19日 · To travel by jet propulsion, a cephalopod such as a squid or octopus will fill its muscular mantle cavity (which is used to get oxygenated-water to their gills) with water and then quickly expel the water out of the siphon.
Siphon On A Squid • Blane Perun's TheSea.Org
2024年5月22日 · The siphon on a squid, also known as the hyponome, is a crucial anatomical feature that plays a significant role in its locomotion and respiration. This article delves into the specifics of the siphon, its functions, and its importance to squid biology.
10 Unique Characteristics of Squid - Wildlife Informer
The siphon of a squid is a tube that extends from the squid’s body and propels it through the water. The siphon has two openings: one on top of the head and one just beneath the mantle collar. When you see a squid swimming in a straight line, it’s actually moving backward because its siphon is pointing in the opposite direction.
Cephalopods: Octopus, Squid, Cuttlefish, and Nautilus
The basic cephalopod body plan includes two eyes, a mantle, a funnel (also called a siphon), and at least eight arms. Some have hard, internal structures, like the cuttlebone in the cuttlefish and the pen in the squid, that evolved from the hard, outer shells of their ancestors, but in many octopuses the hard structure is completely lost.

Squid have a siphon that provides jet propulsion and fins to provide stability and direction when swimming. In fact, squids are the fastest swimmers among the invertebrates with some species reaching speeds of up to 25 mph.
Siphon (funnel): By contracting its mantle, a squid can force a stream of water through the siphon, enabling the squid to quickly jet away from potential danger. Waste, ink, and sperm or eggs leave the squid through the siphon. Tentacle: Squid have 2 tentacles that are equipped with suckers on the large, paddle-shaped
Squid are adapted to a completely aquatic way of life having gills, a streamlined body, reduced shell and a siphon for speedy movement. Squid are considered to be a pelagic animal meaning it spends its life living in the water column.
