They can grow up to be one meter (three feet) tall.
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.
porifera
Many coral reef organisms eat yellow tube sponges like angelfishes, filefishes, cowfishes and spadefish. Also the Hawksbill sea turtle.
i dont think i know ... :P
Tube Sponges are in the Class: Demospongiae, subordinate to the Phylum: Porifera.
Yes they are.
There are 6 different types of sea sponges, the tube sponge, vase sponge, yellow sponge, bright red tree sponge, painted tunicate sponge, and the sea squirt sponge.
Since they are, well, SPONGES, their main purpose is to reproduce by budding, filter feed, and recover from damage by regrowing lost "limbs", if you can call it that.

Yellow tube sponges get their name from their hollow, chimney-like body form. They pump huge quantities of water through their bodies, filtering out the tiny particles on which they feed.The tubes are at least 60cm (24in) high.At shallow depths yellow tube sponges have a shape which resembles a cactus. In deeper waters, the sponges develop long, straight tubes. Their vivid yellow colour is probably due to special fluorescent pigments in the sponge tissue. Yellow tube sponges occur at a wide range of depths in tropical seas, from the surface to several hundred metres down.They are often found in areas with strong currents which facilitate the movement of water into their feeding canals. These sponges are filter feeder that feed on bacteria, plankton and detritus.Sponges are capable of pumping at least five times their own volume of water through their feeding canal every minute. They are able to filter out even the most microscopic bacteria and phytoplankton. Sponges have male and female organs and reproduce sexually. They can also reproduce without sex: if a part breaks off, or fragments, it will form a new sponge.
