The locomotive systems of animals play a key role in behaviours such as foraging, predator
avoidance and migrations. The range of behaviours and morphologies exhibited by animals …

Cuttlefish swim using jet propulsion, taking a small volume of fluid into the mantle cavity
before it is expelled through the siphon to generate thrust. Jet propulsion swimming has …

Locomotion amongst animals is widespread and diverse. Movement is of fundamental
biological importance to animals, enabling them to forage, migrate, pursue prey and mate …

The circular muscles surrounding the mantle cavity of European cuttlefish (Sepia officinalis)
generate the mechanical power to compress the cavity, forcing a jet of water out of the …

Pulsatile jet propulsion is a common swimming mode used by a diverse array of aquatic taxa
from chordates to cnidarians. This mode of locomotion has interested both biologists and …

In the aquatic world jet propulsion is a highly successful locomotion method utilized by a
variety of species. Among them cephalopods such as squids excel in their ability for high …

Squids encounter vastly different flow regimes throughout ontogeny as they undergo critical
morphological changes to their two locomotive systems: the fins and jet. Squid hatchlings …

Jet propulsion concentrates muscle power on a small volume of high-velocity fluid to give
high thrust with low Froude efficiency. Proponents are typically escape artists with high …

The laws of physics are rigid and fixed. Animals, therefore, are restricted in their use of
available energy in accordance to the constraints of mechanics and thermodynamics …

Optimisation of energy by aquatic mammals requires adaptations that reduce drag, and
improve thrust production and efficiency. Drag is minimised by streamlining the body and …
