exercise. Introduction: Our survey of metazoan diversity continues with the clade Bilateria‚ which consists of animals which have bilaterally symmetrical body plans‚ unlike the radially symmetrical Phylum Cnidaria and the largely asymmetrical Phylum Porifera. Additionally‚ members of this clade are triploblastic‚ meaning that they have three embryonic tissue layers from which structures and organs develop‚ in contrast to the diploblastic cnidarians. The clade Bilateria can itself be divided into two
