The phylum is aptly named. Sponge orange band (SOB) is a fatal disease, beginning with lesions on the sponge pinacoderm which spread, producing a transitional orange band and ultimately resulting in total bleaching of the sponge. In this science and art lesson, students discuss what sponges are, create their own sponge, and share what they created with the rest of the class. Giant barrel sponges are leuconoid sponges: water travels through a network of chambers after entering the ostia and before exiting out the osculum, increasing the choanocytes’ filtration efficiency.
