Branching Tube Sponge

This Sponge forms dense clusters of thick-walled tubes in various colors, growing either from a central base or closely side by side. Its surface is covered with knob-shaped bumps, giving it a bumpy, rubbery texture. The inner walls are usually bright yellow, even when the outer color varies widely.

The Branching Tube Sponge can look very different depending on where it grows. It is found from deep reefs to shallow mangroves and often hosts small shrimps in its tubes. It grows slowly, and large individuals may take years to reach maturity. Its toxic tissues help protect it from predators, allowing it to live for many years.
