An illustration of the upper portion of a sponge: p, Pore; s, Subdermal cavity; c1, chief fiver of the skeleton; c2, connecting film. The sponges or poriferans (from Latin porus "pore" and ferre "to bear") are animals of the phylum Porifera. Their bodies consist of an outer thin layer of cells, the pinacoderm and an inner mass of cells and skeletal elements, the choanoderm. Sponges do not have nervous, digestive or circulatory systems. Instead most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes, and the shapes of their bodies are adapted to maximize the efficiency of the water flow.

An illustration of a oyster shell. The common name oyster is used for a number of different groups of bivalve mollusks, most of which live in marine habitats or brackish water. The shell consists of two usually highly calcified valves which surround a soft body. Gills filter plankton from the water, and strong adductor muscles are used to hold the shell closed.

The principal meaning of the German word strudel is whirlpool. Big Strudel, the vortex near Grein, 94 miles upstream of Vienna. These notorious rapids, 165 feet long and 40 feet wide, were a dreaded hazard in Danube navigation before Empress Maria Theresa had some of the most dangerous rocks blasted out of the river bed in 1853. Now at lowest water, the depth is still six feet in the channel. The Strudel no longer exists.
