The behavior of the mesopelagic fish Benthosema glaciale was studied at 60° N in mid‐
summer. We hypothesized that diel vertical migration (DVM) is constrained by short and …

Planktonic organisms feed while suspended in water using various hydrodynamic pumping
strategies. Appendicularians are a unique group of plankton that use their tail to pump water …

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 …

Colonial animals are composed of clonal individuals that remain physically connected and
physiologically integrated. Salps are tunicates with a dual life cycle, including an asexual …

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 …

Aquatic organisms often employ maneuverable and agile swimming behavior to escape
from predators, find prey, or navigate through complex environments. Many of these …

Siphonophores are ubiquitous and often highly abundant members of pelagic ecosystems
throughout the open ocean. They are unique among animal taxa in that many species use …

Underwater compliant-body jet propulsion is among the most efficient of all animal
locomotion. Multi-jet propulsion, a less common method of transit used by the Salp, offers a …
