Squid have more than one way to get around. One way is to cruise at slow speeds using the paired fins at the rear of the mantle, combined with gentle, rhythmic pulses of water pushed out of the mantle cavity through the funnel.

Volumes calculated using the two techniques differed by less than 0.5 ml, i.e. less Mechanics of squid locomotion 2853 than 1 % of resting mantle cavity volume. Note that the squid is treated as axisymmetric. Deviations from axisymmetry could lead to over- or underpredictions of volume flow.

The first is described and critiqued in detail elsewhere (see Thompson and Kier, 2001a ) and we include a brief description here. We attempted initially to measure the kinematics of the mantle during escape-jet locomotion in free-swimming squid.

LOCOMOTION ; 7. How does it move? Undulating movements of its fins and by jet propulsion ... 13. Briefly describe the blood flow in the squid: Branchial hearts pump de-oxygenated blood to gills where oxygen is taken up. The blood then flows back to the systemic heart where it is pumped to the rest of the body.

Squid and octopuses also take advantage of another locomotory method to a greater extent than other cephalopods. They use the mantle cavity and siphon as a jet propulsion system. They take in water and rapidly expel it through the siphon and shoot backwards. ... Squid are the best at this mode of locomotion.

Jet propulsion locomotion in squid (class Cephalopoda, phylum Mollusca) ... As in all molluscs, an umbrella-like mantle surrounds most of the squid's body. In squids, however, the mantle is highly muscular. Mantle muscles change the thickness ... Water is pumped through this cavity for both locomotion and respiration.
