Regeneration

After autotomization, regenerating cerata in Berghia stephanieae can be seen after just a couple of days.

Cerata regenerate at an average of 0.09 mm/day.

Cerata regain ~90% of original length within 23-24 days. (Dotted green line represents the average starting length of cerata prior to autotomization and the green box represents the standard deviation of this mean.)

At four hours after removal of rhinophores, in Berghia, immunohistochemistry with antibodies to H3P indicates numerous cells undergoing cell division (green dots).
