Abstract
Pre-metamorphic planulae of the scyphozoan C. xamachana contain 4 cell types. The ectoderm consists of supportive cells and differentiating nematoblasts and nematocytes, while the endoderm consists of supportive cells and interstitial cells. Neural elements and glandular cells are absent in these planulae. Morphological similarities and differences that exist among hydrozoan, scyphozoan and anthozoan plaulae are discussed.This publication has 1 reference indexed in Scilit:
