AN EXAMPLE OF REVERSAL OF POLARITY DURING ASEXUAL REPRODUCTION OF A HYDROID

CADET HAND 1 and MEREDITH L. JONES 1

1 Department of Zoology, University of California, Berkeley, California

1. Asexual reproduction, involving reversal of the original oral-basal polarity, is described.

2. Asexual reproduction in this hydroid leads to the production of pairs of polyps sharing a common base.

3. The systematic position of the hydroid is not established, although the cnidom suggests possible affinities among the gymnoblasts.
