Resumo

A method of asexual reproduction previously unrecorded is described for Obelia articulata and Obelia geniculata.When water temperatures markedly exceed about 20° C. presumptive gonangial outgrowths continue growth as massive stolonic terminals that rapidly constrict off, leave the colony and settle elsewhere to establish new colonies in large numbers. In size and potentiality these reproductive units somewhat exceed those of typical campanulid planulae.
