Movements and Co-ordination of the Ciliary Comb Plates of the Ctenophores Beroe and Pleurobrachia

Naturevolume 199pages620621 (1963) | Download Citation



INVESTIGATIONS by Afzelius1,2 on the comb plates of Mnemiopsis showed that these plates are compound structures built up from several hundred thousand cilia of somewhat modified structure, the shafts of which are apparently cemented together in long rows. The comb plates of the smaller ctenophores used in this work contain fewer cilia, but even here many thousands of cilia must be incorporated in each plate.
