Abstract In 1953 the author described a regression and replacement cycle of hydranths in Laomedea flexuosa and proposed that this is a common feature of thecate hydroids. Here examples are presented of replacement of hydranths in species from 5 families of thecates, but it has not been demonstrated that this is as common as had been thought. More continuous studies are needed. A brief consideration is given to the origin of hydrothecae and their development.
