Die Metamorphose des Polypen vonTripedalia cystophora (Cubozoa, Carybdeidae) in die Meduse
Metamorphosis of the polyp ofTripedalia cystophora (Cubozoa, Carybdeidae) into the medusa
Helgoländer Meeresuntersuchungen volume 36, pages 257–276 (1983)
Abstract
The life cycle of the Cubozoa is unique due to the complete metamorphosis of the sessible solitary polyp into one single medusa which starts a pelagic way of life. Contrary to the other metagenetic classes of Scyphozoa and Hydrozoa, the cubozoan polyp terminates its polypoid existence definitely when it metamorphosizes. Generally, the metamorphosis of the cubopolyp is characterized by the transformation of its simple, sac-like multiradial body into the tetraradial structures of the much more complicated medusa. The macroscopic phases of the metamorphosis ofTripedalia cystophora Conant are reviewed, and the internal developmental processes which effect and underlie the transformation are described in detail from new histological investigations. Only the oral pole of the polyp is involved in the active processes of transformation whereas the basal pole follows in a more passive way. The most important process is the invagination of a quadrangular furrow around the hypostome of the polyp by which (a) the subumbrellar room (bell cavity) of the developing medusa is formed, and (b) the four gastric pockets within the wall of the bell are folded off from the polyp's simple stomach. The description of the metamorphosis on the whole and the detailed comparison of the principal developmental processes provide evidence that medusa formation of Cubozoa is different from that of the other metagenetic classes of Scyphozoa and Hydrozoa. The systematic and evolutionary consequences as well as general aspects of medusa formation in the phylum Cnidaria are discussed in detail. In conclusion, the pelagic medusa generation has been “invented” by the ancestors of the recent metagenetic cnidarian classes three times independently.
