A class of planktonic, jet-propelled tunicates. The class Thaliacea is composed of three different orders: Pyrosomatida (alternatively known as Pyrosomida), Salpida, and Doliolida. All thaliaceans have remarkable reproductive cycles, involving alternation of asexual (oozooids) and sexual (blastozooids) generations. Doliolid life cycles are the most complex of any nonparasitic animal. All three groups are significant ecologically, as they are highly efficient filter-feeding herbivores that can form immense swarms. See also: Tunicata (Urochordata); Zooplankton
