The nitrogenous metabolic excretory waste usually contains ammonium compounds. The fine lateral channels connect the marginal channels with the radial perihaemal sinuses. The dermis contains an endoskeleton of calcium carbonate components known as ossicles. Both bipinnaria and brachiolaria larvae are bilaterally symmetrical. The functions of these chemicals in the starfish have not been fully investigated but most have roles in defence and communication. In each arm, the radial canal gives out two series of short, narrow, transverse branches called lateral or podial canals. The edges of adjacent paxillae meet to form a false cuticle with a water cavity beneath in which the madreporite and delicate gill structures are protected. The only thing you should know are the different classifications and then prepare a chart. However, the scientific name L.

    Each pair of ambulacral ossicles has an upper and a lower transverse ambulacral muscle, the upper or superior transverse ambulacral muscle widens the ambulacral groove, and the lower or inferior transverse ambulacral muscle makes the ambulacral groove narrow.

Each lateral canal is attached to the base of a tube foot and is provided with a valve to prevent backward flow of fluid into the radial canal.
