Observations on the reproduction, early larval development, and colony astogeny of Conopeum tenuissimum (Canu)

  • Judith E. Dudley


Embryology of the ectoproctConopeum tenuissimum was followed from egg extrusion to three days and colony development from settlement to about seven days (20 generations of zooids). The cyphonautes larvae are rare in plankton, perhaps for behavioral reasons. Astogenetic change occurs for about 10 days, but some features reach a state of repetition more rapidly than others. The small colony size, rapid growth and reproduction show that this ectoproct possesses an “opportunist” life strategy, particularly well adapted to estuarine conditions.
