Bioenergetics and growth in the ctenophore Pleurobrachia pileus

Hydrobiologia, 2010
Knowledge of how energetic parameters relate to fluctuating factors in the natural habitat is necessary when evaluating the role of gelatinous zooplankton in the carbon flow of coastal waters. In laboratory experiments, we assessed feeding, respiration and growth of the ctenophore, Pleurobrachia pileus, and constructed carbon budgets.

Ciliary Movement and the Density of Pleurobrachia

Nature, 1942
THE density of the living Ctenophore Pleurobrachia pileus (O. F. M. ) has been determined recently at Plymouth by two distinct methods. In the first case ten specimens all having the approximate diameter of 1 cm. were introduced into a 5 ml. density bottle, together with sea water, and weighed.

Neurociliary synapses in Pleurobrachia (Ctenophora)

Journal of Cell Science, 1964
ABSTRACT Synapses of a typical form, with synaptic vesicles of 30 to 45 mµ diameter, on one side of a synaptic cleft of 10 to 12 mµ, are found near the bases of the long ciliated cells which make up the comb plates. The side containing the vesicles is interpreted as a section of a nerve fibre terminal in contact with the ciliated cell ...

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

Ecology, 1986
Ctenophores and other gelatinous predators in the ocean are ephemeral in their spatial and temporal distributions, but often have a dramatic impact on the dynamics of their prey populations. Considerable information is currently available on the functional and numerical responses of several nearshore ctenophore species; however, an understanding of ...

Distribution and abundance of ctenophores, and their zooplankton food in the Black Sea. I. Pleurobrachia pileus

Marine Biology, 1999
The distribution of Pleurobrachia pileus Muller, 1776 in the Black Sea was determined using plankton samples collected above the anoxic zone (maximum of 200 m) in the winter, spring, and summer of 1991 to 1995. The summer samples were collected in 1991 to 1993 (for a previous) and are included in this paper for comparative purposes. High concentrations

Bioluminescence of Ctenophore Pleurobrachia pileus (O. F. Müller, 1776) in the Summer Period

Biophysics, 2023
The capability of bioluminescence has been found in many marine hydrobionts, including almost all representatives of the phylum Ctenophora. The glow of species and bioluminescent substrates isolated from them is actively used in biology, ecology, and medicine to study the physiological state of an organism or to identify unfavorable environmental ...

Observations on the Ecology ofPleurobrachia Pileus(Ctenophora) in the Southern Benguela Ecosystem

African Journal of Marine Science, 2003
The vertical distribution, abundance and size composition of a population of Pleurobrachia pileus was studied during a six-day drogue study conducted off the west coast of South Africa in February 1995.

Impact of formalin preservation on Pleurobrachia bachei (Ctenophora)

Journal of Experimental Marine Biology and Ecology, 2004
Abstract Here, we report on the impact of formalin preservation on the physical dimensions of the tentaculate ctenophore Pleurobrachia bachei A. Agassiz collected in the North East Pacific Ocean. Contrary to previously published papers [Oorthuyzen, W., Sadee, C., 1982.

Zur Entwicklung der Kolloblasten von Pleurobrachia pileus (Ctenophora)

Marine Biology, 1974
Electron microscopic investigation of young Pleurobrachia pileus has shown that the colloblasts develop from ciliated cells containing rich endoplasmic reticulum. The cilium is connected with the cell-body by means of a thin strand of cytoplasm; the cilium grows spirally around the basal part of the cell and undergoes several modifications; its rootlet
