Untersuchungen zum Körperbau von Meeresschwämmen. II. Das Wasserleitungssystem von Halichondria panicea

Abstract

The water-conducting system of Halichondria panicea (Pallas) shows the classical eurypylous type. The excurrent system consists of a multiple anastomosing network of channels, within which numerous flagellated chambers are embedded in such a way that their apopyles open into the excurrent canals. Each flagellated chamber communicates with the incurrent system by way of several prosopyles. © 1983 Biologische Anstalt Helgoland.
