Paleophragmodictya are among the oldest life forms in this phylum. Cladorhizadae are a carnivorous family in this phylum, while some of its members use the totipotent archeocytes to reproduce. Members of this phylum have excretory structures called oscula, and their silica-based skeletal structure is secreted by sclerocytes. Apopyles are pores which allow water to enter the atrium from the choanocyte chamber in the syconoid arrangement for them, and they are also found in asconoid and leuconoid types. All members of this phylum possess a gelatinous tissue called the mesohyl. For 10 points, identify this phylum of animals commonly referred to as sponges.
