From this holdfast, the sponge produces long, branching structures with nodes that give rise to clusters of four to six club-shaped appendages.

The ping pong tree sponge is an important component of deep-sea ecosystems, providing habitat and food for a variety of organisms.

The sponge's feeding structures are covered with tiny hooks that capture small crustaceans and other invertebrates, making it a primary consumer in the deep-sea food web.

The expedition collected a variety of deep-sea organisms, including the "Eltanin Antenna", an unusual structure that was later confirmed to be an individual of the C. concrescens species.

Today, the ping pong tree sponge remains an important subject of study for marine biologists, who continue to explore the mysteries of the deep-sea ecosystem.
