they are filter feeding animals so when the flagella or little sticky whips inside flip around it collects oxygen from the water
a type of sponge that is purple
tube sponges come in many natural colors such as brown, dull green and yes, yellow. secondly tube sponges reproduce by spliting their selves in half. so i guess their only family is the one sponge.
Purple tube sponges have few natural enemies due to their chemical defenses and habitat preferences. However, they may be consumed by some predators, such as sea urchins, certain nudibranchs, and some fish species. Overcrowding and competition for space with other filter feeders can also pose a threat to purple tube sponges.
All sponges don't have respiratory organs. Instead, individual sponges breath for the sponge.
Yes they are.
they have thungs and mungs

This is from www.reefnews.com: This Purple Tube Sponge colony lives on a dead coralhead. The coral may have succombed to the algae and sponges that grew over the polyps and killed them. Now the skeleton of the coral supports a variety of sponges and algae. Sponges are colonies of thousands of individual cells. The cells work together, pumping water through the body of the sponge. The tall tube is in the shape of a "chimney." This chimney is an exhaust tube, where the water pumped by the sponge comes out. The sponge eats the plankton it filters out of the water as the water is pumped through the body of the sponge. Animals that eat sponges and algae help to keep a healthy balance on the reef. If there are too few of these animals, then the sponges and algae may take over. Examples of algae eaters are Parrotfishes, Sea Urchins, and Crabs. Examples of sponge eaters are Hawksbill Turtles and Loggerhead Turtles.
