This research aims to study morphological ossicles of sea cucumber Paracaudina australis which belongs to Ordo Molpadida and Family Caudinidae. Samples P australis were taken randomly from the Kenjeran Waters, Surabaya. Samples P. australis were preserved by alchohol 96% for studying ossicles. According the research result, the types of ossicles in dorsal and ventral were dominated by button, rod and eyeglasses shape. In the dorsal tissue and ventral tissue, there are no rod shape bone. Calcarious ring of P. australis conssists of 16 radial shapes and 12 interradial shapes. Ossicles shapes in the anterior tissue are more variety than in the posterior tissue. Its conclude that the eyeglasses shape and number 8 shape are dominant in all of tissue P. autralis .
