Porifera - The Sponges
1. Purchase a sponge skeleton from a Paint Department. Sponge skeletons are currently popular as paint applicators. Using a hand lens, identify the pores, the spicules and the spongin. What parts of the sponge are no longer present? To which class would the specimen likely belong?
2. Make a drawing of your purchased specimen, and label the parts that you are able to identify.
