Volcano / Fire Sponge GALLERYTedania klausi/ Tedania ignis
At one time the Volcano Sponge and the Fire Sponge were thought to be the same species. They have now been classified as two separate species. They are still hard to tell apart. These pictures are not scientifically identified, but I know from experience that these pictured sponges leave irritating, burning areas on your skin if touched.
