Nature of the Metamorphic Signal and its Internal Transduction in Larvae of the Nudibranch Phestilla Sibogae
The veliger larvae of the coral-eating nudibranch mollusc Phestilla sibogae have provided an excellent model for the study of chemical-induction of metamorphosis. They metamorphose only in response to a water-soluble metabolite that escapes from the coral prey of the adult nudibranchs. Metamorphosis...

| Zusammenfassung: | The veliger larvae of the coral-eating nudibranch mollusc Phestilla sibogae have provided an excellent model for the study of chemical-induction of metamorphosis. They metamorphose only in response to a water-soluble metabolite that escapes from the coral prey of the adult nudibranchs.
Metamorphosis, occurring 18-20 h after larvae are exposed to coral, is decisive: larvae attach to a substratum, shed their velar-swimming organs, shell and operculum, and undergo major morphological reorganization. Extraction and HPLC purification of the coral product show it to be a
