Cuvierian Tubules: A Sticky Defense
Some sea cucumbers have a bundle of tubes (Cuvierian tubules) attached to the respiratory tree, which they expel through the anus. The tubules elongate and become sticky in seawater, entangling crabs and fish. They also contain toxic saponins, and are regrown.
Home for a Fish
A slender pearlfish sometimes lives inside the sea cucumber's body cavity, entering through the anus. The fish emerges at night to feed, and the cucumber appears to tolerate the arrangement.
Reef Recyclers
Like the sandfish, it feeds on sediment and processes it, which recycles nutrients on the reef. See Sandfish Sea Cucumber.
