The Yellow Tube Sponge has bright yellow to orange tubes with soft, wrinkled surfaces. In shallow water, it grows in clusters of shorter tubes, while in deeper water, it often grows as a single, unbranched tube.
The Yellow Tube Sponge can be found in dark areas with little sunlight, such as under large piers and inside wrecks.
