The Stovepipe Sponge (Aplysina archeri) is a species of tube sponge found mainly in the Atlantic Ocean, including the waters around the Caribbean, Bahamas, Florida, and Bonaire. This species has long tube-like structures cylindrical in nature and many tubes are attached to one particular part of the organism. The tubes occur in varying colors including lavender, gray and brown. The Stovepipe Sponge is a filter feeder and eats food such as plankton or suspended detritus as it passes by them. Very little is known about its behavioral patterns except for its feeding ecology and reproductive biology.

A sponge gets its oxygen from the water. The oxygen moves from the water to the sponge by a process called diffusion. Diffusion is when molecules of a substance move from an area where they are highly concentrated to an area where they are less concentrated. Oxygen is more highly concentrated in the water then in the sponge. Therefore, the oxygen goes from the water to the sponge.
