Vauxia is an extinct genus of demosponge that had a distinctive branching mode of growth. Each branch consisted of a network of strands. Vauxia also had a skeleton of spongin (flexible organic material) common to modern day sponges. Much like Choia and other sponges, Vauxia fed by extracting nutrients from the water.
Vauxia is named after Mount Vaux, a mountain in Yoho National Park, British Columbia. It was first described in 1920 by Charles Doolittle Walcott.[2]
