Porifera (Sponges) The phylum Porifera (the sponges) includes about 5000 species almost all of which are marine (there are about 150 freshwater species, members of the family Spongillidae). They are diploblastic animals with two layers, the outer dermal layer and the inner gastral layer. Metazoan Characteristics A. Phylum Porifera - Sponges – Primarily marine animals that consist of loosely organized cells; approx 9k spp, from < 1cm to > 1m. Range in size from a few millimeters to 2 meters across. This helps sponges live and survive in their habitats. Previous molecular studies have revealed many discrepancies between classically recognized taxa and the observed relationships at the order, family and genus levels; these inconsistencies question underlying hypotheses regarding the evolution of certain morphological characters.

Phylum Porifera- Leuconoid Type Sponge. Reproduction: Asexually by fragmentation and gemmule formation. Cetak. Porifera, also known as sponges, are the types of phylum that live underwater. This phylum is different from other types because the porifera has many cells that cover their exoskeleton. These cells each have different types of functions. For example, because the sponge does not have a mouth , they use their tiny pores on their body. Body Plan III. All adults are sessile and attached to substratum. Characteristic Features of Phylum Porifera. II. Asexual and Sexual Reproduction Genetically identical cells are produced from a single parent cell by mitosis. The reproductive ecology of most sponges has never been studied, so it is hard to answer the question “how do sponges reproduce”.
