Different species of Vauxia have different appearances, and are distinguished by the shapes of their branches. Some species have simple, unbranched forms while others have very long and complex branches. Vauxia can reach up to 15 centimeters in height, although 8 centimeters is more common.
Vauxia was originally believed to be a type of glass sponge, but J. K. Rigby reclassified it as a demosponge in 1980. There are six or seven known species, and the type species is V. gracilenta.
