Early Development and Planula Movement in Haliclystus (Scyphozoa: Stauromedusae)

  • Joann J. Otto


Stauromedusae are unusual scyphozoans in that they are sessile and live attached by a stalk to eel grass or algae. Their planula larva is also unusual since it creeps about rather than using ciliary locomotion and since it has a constant number of endodermal cells (Kowalevsky, 1884; Wietrzykowski, 1910, 1912; Hanaoka, 1934).
