In situ swimming and feeding behavior of eight co-occurring hydromedusae

The morphology, swimming kinematics and prey selection of hydromedusae have been shown to be closely related to hydromedusan foraging mode. In order to confirm this link, we examined the in situ foraging behavior of hydromedusae by video-recording and quantifying the in situ swimming activity and tentacle-extension behavior of 8 co-occurring hydromedusae from the waters surrounding Friday Harbo...

Morphology, swimming performance and propulsive mode of six co-occurring hydromedusae.

Jet propulsion, based on examples from the Hydrozoa, has served as a valuable model for swimming by medusae. However, cnidarian medusae span several taxonomic classes (collectively known as the Medusazoa) and represent a diverse array of morphologies and swimming styles. Does one mode of propulsion appropriately describe swimming by all medusae? This study examined a group of co-occurring hydro...

A wake-based correlate of swimming performance and foraging behavior in seven co-occurring jellyfish species.

It is generally accepted that animal-fluid interactions have shaped the evolution of animals that swim and fly. However, the functional ecological advantages associated with those adaptations are currently difficult to predict on the basis of measurements of the animal-fluid interactions. We report the identification of a robust, fluid dynamic correlate of distinct ecological functions in seven...

Larval feeding behavior of three co-occurring species of container mosquitoes.

Interspecific differences in foraging behavior may help to determine whether the outcome of interspecific competition is coexistence or exclusion. Mosquitoes in the genus Culex are commonly described as foraging primarily by filtering the water column. This behavior contrasts with that of other container-dwelling genera, such as Aedes and Ochlerotatus, that are thought to forage primarily by br...
