Yellow Tube Sponges are filter feeders that take in water through numerous tiny pores while filtering out tiny food items like plankton and other organic material.
They are crucial contributors to coral reef ecosystems because they house a variety of small invertebrates and provide food for some larger predators, like the Hawksbill turtles and specific fish species.
