On my pages I will be covering the cardiovascular systems of animals from the phylums of Anthropoda, Porifera, and Mollusca. Animals under the phylum Anthropoda have and exoskeloton, a segmented body, and jointed appendages. Animals in the Porifera phylum haveFor the phylum of Anthropoda I chose the Sea Spider, Japanese Spider Crab, and the Southern Giant Darner. For Porifera I chose the Giant Barrel Sponge, the Touch-Me-Not-Sponge, and the Vase Sponge. And for Mollusca I chose the Giant Clam, the Giant Squid, and the Garden Snail.
