- according to Hottinger (2006):
EPHEBIC - "adult", i.e. a post-nepionic growth stage during which the features characterizing the shell architecture remain constant. The ephebic stage may grade into a later gerontic stage where the architectural features risk becoming irregular, or are altered to form brood chambers, as is often observed in the microspheric generation of larger, complex foraminifera.
