Hi Mr. Revell,

I am working with the sea slug Chelidonura sandrana. I read that they feed the algae Isochrysis galbana and you have used it for your experiment as well. Where did you get the algae and do you have any experiences to feed them to the cephalaspid C. sandrana adult/larvae?

Locality: Lizard island, Queensland, Australia

Dear Johannes,
I am not sure if Duncan will be reading the Forum regularly - it's possible he still uses the email address on his message which may be worth trying. Isochrysis galbana is one of the standard unicellular algae cultured for laboratory and aquarium studies, and often used for veliger larvae culture. I think seed cultures can be obtained from biological supply houses and possibly other labs. The problem with culturing veliger larvae is not just a  food supply but the need to keep the culture free of  harmful bacteria and other organisms which may attack the veligers. Another physical problem is the way veligers after often attracted to th light and consequently get caught in the surface film and die. We are pretty sure that all adult Chelidonura feed on small flatworms.

I would be interested to know what work you are doing at Lizard Island on Chelidonura sandrana. It is proving to be a popular research topic

Best wishes,
Bill Rudman
