Localization of digestion activities in the sea anemone Haliplanella luciae.
The Biological Bulletin; 10/1/1995; Bumann, Dirk; 787 words
; Among Cnidaria, the Anthozoa have many radial septa called mesenteries, which project from the body wall into the gastric cavity. Anthozoa are typically larger than other cnidarians and therefore might have needed to increase their inner surface/body weight ratios. Therefore, a generally proposed

Direct observation of contact digestion in inside-out oriented Aurelia aurita polyps.
The Biological Bulletin; 10/1/1996; Bumann, Dirk Kuzirian, Alan; 769 words
; 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
