Biological cycle of Pelagia noctiluca: morphological aspects of the development from planula to ephyra

  • L. Rottini Sandrini
  • M. Avian


The development of Pelagia noctiluca (F\(\mathop o\limits^o\)rskal) larvae, obtained from fertilization in aquarium, has been observed and recorded from the stage of planula to the stage of ephyra of 1.4 mm in diameter. Nine developmental stages are described, corresponding to the variation in the general morphology, in the morphology of the gastrovascular cavity, of the marginal arms and of the neuromuscular system.
