Stovepipe Sponge

Also known as Stove Pipe Sponge, Caribbean Tube Sponge

Stovepipe sponges rise in dramatic vertical clusters from Caribbean reefs, forming architectural colonies of up to twenty-two hollow cylinders that can reach well over a meter tall. These colonial animals continuously pump thousands of liters of seawater through microporous tissue walls each day, stripping bacteria and organic debris before discharging filtered water through open apical oscula. Because they grow at exceptionally slow rates of mere millimeters per year, large clusters represent delicate reef communities that have developed undisturbed across centuries.
