The fact that not only aeolidioids but other nudibranchs sequester zooxanthellae (seemingly retaining their functionality) appears to be a preadaptation for an easy next step to sequestration of nematocysts - also for their functionality. If this originally evolved merely to protect the nudibranch without taking advantage of the nematocyst's defensive properties, why would they be sequestered at the ends of the cerata - precisely where they would be most useful for defense - rather than within the gut to be eventually excreted as waste?<BR/><BR/>p.s. not a professional evolutionist, I just play one on the internet ;-)Anonymousnoreply@blogger.com
