“…Like other lobates, the feeding rate of B. infundibulum is high (Gamble 1974(Gamble , 1977, and closely related lobates are known to control their prey populations . Species of the genus Beroe feed primarily on other ctenophores (Swanberg 1974, Harbison et al 1978 and may significantly affect the population structure of B. infundibulum, and thus indirectly modify the population dynarnics of other zooplankton a t lower trophic levels (Kamishlov et al 1958, Kamishlov 1960.

Annual cycles of abundance of the ctenophore species Bolinopsis ~nfundibulum and Beroe cucumls wel-e studied in the Malangen fjord, northern Norway, during 1992. The seasonal dynamics were characterized by alternating abundances of the 2 species A biomass increase of B infundibulum occurl-ed in April and May, I-eaching a peak of 2 to 7 m1 m-.' wet volume in the surface layers in summer. The specles started to reproduce in the inner part of the fjord, and then propagated throughout the entire fjord system. Length frequency distributions indicated that B. infundibulum were reproducing continuously d u n n g the summer months. Biovolumes of B. infundibulum decreased in August, leaving a small number of individuals (

“…Ctenophores are exceptionally fragile, easily fragmented by nets and trawls, but knowledge of the phylum has increased greatly due to individual collection of undamaged specimens in containers by scuba divers, submersibles and remotely operated vehicles (ROVs) (Swanberg 1974;Hamner 1975;Hamner et al 1975;Harbison et al 1978;Madin 1990;Robison 1999;Youngbluth and Båmstedt 2001;Gasca and Haddock 2004). Further, submersibles and ROVs collect and record video below scuba diving depths, essential for behavioral research on midwater and deep-sea animals (Hamner 1985).…”

Feeding behavior of the ctenophore Thalassocalyce inconstans: revision of anatomy of the order Thalassocalycida

Behavioral observations using a remotely operated vehicle (ROV) in the Gulf of California in March, 2003, provided insights into the vertical distribution, feeding and anatomy of the rare and delicate ctenophore Thalassocalyce inconstans. Additional archived ROV video records from the Monterey Bay Aquarium Research Institute of 288 sightings of T. inconstans and 2,437 individual observations of euphausiids in the Gulf of California and Monterey Canyon between 1989 and 2005 were examined to determine ctenophore and euphausiid prey depth distributions with respect to temperature and dissolved oxygen concentration [dO]. In the Gulf of California most ctenophores (96.9%) were above 350 m, the top of the oxygen minimum layer. In Monterey Canyon the ctenophores were more widely distributed throughout the water column, including the hypoxic zone, to depths as great as 3,500 m. Computer-aided behavioral analysis of two video records of the capture of euphausiids by T. inconstans showed that the ctenophore contracted its bell almost instantly (0.5 s), transforming its Xattened, hemispherical resting shape into a closed bi-lobed globe in which seawater and prey were engulfed. Euphausiids entrapped within the globe displayed a previously undescribed escape response for krill ('probing behavior'), in which they hovered and gently probed the inner surfaces of the globe with antennae without stimulating further contraction by the ctenophore. Such rapid bell contraction could be eVected only by a peripheral sphincter muscle even though the presence of circumferential ring musculature was unknown for the Phylum Ctenophora. Thereafter, several live T. inconstans were collected by hand oV Barbados and microscopic observations conWrmed that assumption.

“…Upon encountering a predator such as Beroe spp, a prey ctenophore stands little chance of survival (Swanberg, 1974;Harbison et al, 1978;Falkenhaug, 1996;. The chemical presence of prey ctenophores triggers search behavior of Beroe spp.…”

Although many studies have focused on Mnemiopsis leidyi predation, little is known about the role of this ctenophore as prey when abundant in native and invaded pelagic systems. We examined the response of the ctenophore M. leidyi to the predatory ctenophore Beroe ovata in an experiment in which the two species could potentially sense each other while being physically separated. On average, M. leidyi responded to the predator's presence by increasing variability in swimming speeds and by lowering their vertical distribution. Such behavior may help explain field records of vertical migration, as well as stratified and near-bottom distributions of M. leidyi.
