Systematics and Biogeography of the Jellyfish Aurelia labiata (Cnidaria: Scyphozoa).

From: The Biological Bulletin | Date: August 1, 2001| Author: GERSHWIN, LISA-ANN | Copyright information

Abstract. The hypothesis that the common eastern North Pacific Aurelia is A. aurita is falsified with morphological analysis. The name Aurelia labiata is resurrected, and the species is redescribed, to refer to medusae differing from A. aurita by a suite of characters related to a broad and elongated manubrium. Specifically, the oral arms are short, separated by and arising from the base of the fleshy manubrium, and the planulae are brooded upon the manubrium itself, rather than on ...

Collection and culture techniques for gelatinous zooplankton.
The Biological Bulletin ; Abstract. Gelatinous zooplankton are the least understood of all planktonic animal groups. This is partly due to their fragility, which typically precludes the capture of intact specimens with nets or trawls. Specialized tools and techniques have been developed that allow researchers and aquarists

The Biological Bulletin ; MICHAEL N. DAWSON [12 DAVID K. JACOBS [1] Morphological taxonomy suggests that marine faunas are species poor compared to terrestrial and freshwater faunas (1). This dichotomy has been attributed to the unique potential of marine plankters for distant dispersal across homogenous oceans with few

The Southern Review ; Aurelia aurita No planet could keep so many moons in tow. They drift, constantly unconstellating around you in their milky way. Even to want to cradle one in your palm would compromise their elegance: The opaque domes are stippled with a compass rose and trail, like auroras, fine, voluted veils.

Effect of salinity on ionic shifts in mesohaline scyphomedusae, Chrysaora quinquecirrha.
The Biological Bulletin ; Introduction Most members of the phylum Cnidaria are marine. Only a few hydrozoans (e.g., Craspedacusta) live in fresh water. Some cnidarians occur in low-salinity waters, but species diversity decreases sharply with decreased salinity (Dumont, 1994). In Chesapeake Bay, medusae of the scyphozoan
Direct observation of contact digestion in inside-out oriented Aurelia aurita polyps.
The Biological Bulletin ; Extracellular digestion in a scyphozoan polyp has been assumed to be mediated by digestive enzymes freely secreted into the small and simple gastric cavity ( luminal digestion ) (1). But, histological examination of Aurelia aurita polyps, fixed at various time intervals after ingestion of an
Oxygen consumption rates and metabolic enzyme activities of oceanic California medusae in relation to body size and habitat depth.
The Biological Bulletin ; Abstract. Oxygen consumption rates were measured in 14 species of hydromedusae and 5 species of bathypelagic coronate scyphomedusae. Analysis of all individuals of all species of medusae showed the familiar pattern of decreasing specific oxygen consumption rate with increasing wet weight of
Swimmers warned to steer clear of jellyfish swarms.(News)
Daily Post (Liverpool, England) ; SWIMMERS were yesterday warned to steer clear of an armada of stinging jellyfish spotted off the North Wales coast. The alert came after more than 1,000 moon jellyfish were washed ashore at Black Rock Sands, in Morfa Bychan. Experts said the jellyfish were brought to North Wales by warm currents.
