SummaryCilia bundled into combs or ctenes are an evolutionary innovation that allow comb jellies (animals in the phylum Ctenophora) to swim faster and grow to sizes at least two orders of magnitude larger than animals that propel themselves by beating single cilia. Ctenophore size, shape and swimming behaviors, however, may be constrained by the mechanisms that coordinate comb plate oscillations.Oscillations of comb plates onPleurobrachia bachei (a cydippid comb jelly), are coupled by fluid… 

Eoandromeda and the origin of Ctenophora

The Ediacaran fossil Eoandromeda octobrachiata had a high conical body with eight arms in helicospiral arrangement along the flanks, and was interpreted as an early stem‐group ctenophore, characterized by the synapomorphies ctenes, comb rows, and octoradial symmetry but lacking crown‐group synapomorphicies.

Jellyfish Body Plans Provide Allometric Advantages beyond Low Carbon Content

It is concluded that low carbon and high water contents alone do not explain the differences in the intercepts or slopes of the allometric relationships of jellyfish and other pelagic animals and that the evolutionary longevity of Jellyfish and their propensity to form blooms is facilitated by their unique body plans.

3-Dimensional fluid flow profile on a structured PDMS surface

We present a device capable of transporting fluid in an open system along a wall without rotating parts using cilia-like comb rows. For the first time, we show a 3-dimensional image of the flow field



Mechanisms of Ciliary Co-Ordination in Ctenophores

The results showed that the comb plates of cydippids and beroids are co-ordinated by mechanical forces arising from the movement of the plates themselves, and that ciliary co-ordinate may be entirely neuroid in lobate ctenophores.

Relations between Metachronism and the Direction of Ciliary Beat in Metazoa

The incidence of dexioplectic and laeoplectic metachronism is not influenced by morphological reversals of symmetry such as the situs inversus, and the relation between the direction of beat and thedirection of the waves is probably determined by cytological or stereochemical factors, rather than by gross morphology.


The colloblast appears to be a disposable capture cell and a new scheme of its organization is described and discussed with respect to functional mechanics and phylogeny.

Unilateral ciliary reversal and motor responses during prey capture by the ctenophore Pleurobrachia.

High-speed cinematography of feeding Pleurobrachia revealed a stereo-typed sequence of ciliary motor responses underlying the feeding behaviour of this ctenophore, particularly the unilateral reversal of comb rows on the catching side.


It is shown mathematically that the bursts of continuous swimming typical of these yolk-sac larvae is the more efficient form of Locomotion at this stage, because of their small size, and this advantage changes as the larva grows out of the size range in which water viscosity is the dominant factor.

Foraging Behavior and Prey Selection by the Ambush Entangling Predator Pleurobrachia Bachei

It is concluded that Pleurobrachia's diet is determined by the relative availability and vulnerability of prey, and that vulnerability to the ctenophore can be predicted from prey swimming speeds and the susceptibility of prey after encounter.

Nutritional Ecology of Ctenophores—A Review of Recent Research

Introduction to the Scaling of Aquatic Animal Locomotion

This introductory lecture attempts to discuss the scaling problems related to the locomotion of aquatic animals in two major categories characterized by low and high Reynolds numbers of swimming motion, with consideration of hydromechanical efficiency and physiological function.
