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 …

Many fishes employ distinct swimming modes for routine swimming and predator escape.
These steady and escape swimming modes are characterized by dramatically differing body …

The marine tintinnid ciliate Amphorides quadrilineata is a feeding-current feeder, creating
flows for particle encounter, capture and rejection. Individual-level behaviors were observed …

The marine oligotrich ciliate Strombidium capitatum is a cruise-feeder, relying on ciliary
motion and propulsion flow to individually detect and capture particles. High-speed, high …

Helical motion is prevalent in nature and has been shown to confer stability and efficiency in
microorganisms. However, the mechanics of helical locomotion in larger organisms (> 1 …

Using valves to control the direction of internal flow for effective swimming, the jet-propulsion
method of sea salp (a barrel-shaped marine invertebrate) provides a promising locomotion …

Vortex ring formation process in starting jets with uniform background co- and counter-flow
Page 1 J. Fluid Mech. (2023), vol. 968, A26, doi:10.1017/jfm.2023.586 Vortex ring formation …

We numerically investigate the dynamics of a self-propelled system that swims by using
intermittent jet propulsion through cyclic body deformations. Unlike existing studies, the …

Morphological features are the primary identifying properties of most animals and key to
many comparative physiological studies, yet current techniques for preservation and …

The influence of uniform background co-flow on the propulsive characteristics of starting jets
with stroke ratios (length to diameter ratio, L/D) from 1 to 5 and velocity ratios (ratio of co-flow …
