ovoviparous viviparous Papulae sing papula also known as dermal branchiae or skin gills are projections of the coelom of Asteroidea that serve in respiration and waste removal Papulae are soft covered externally with the epidermis and lined internally with peritoneum They extend through the mesodermal ossicles and are protected from microscopic larvae by pedicellariae The clitellum is a thick saddle like ring found in the epidermis skin of the worm usually with a light colored pigment To form a cocoon for its eggs the clitellum secretes a viscous fluid Oligochaeta and Hirundinea Oviparous animals that lay eggs with little or no other embryonic development within the mother Ovoviparous embryos develop inside eggs that are retained within the mother s body until they are ready to hatch Viviparous development of the embryo inside the body of the mother eventually leading to live birth
