Berthella - reproduction and larval development?

August 1, 2007
From: Erin Smith

Hi guys,
I am undertaking a short assignment as part of university zoology on Berthella (more specificallyBerthella medietas ) and am hunting information on reproduction and larval development. If anyone could provide any info or point me in the direction of some good journal articles. ( I have already looked at Jeff Goddard's 2004 piece in Can. J Zoology but of course it doesn't talk about Australian species) I would really appreciate it.

Dear Erin,
I wish it were so easy! I often wonder how it is that university students end up with impossible projects like this - did you teacher give you this topic?  I am pretty sure the only information available on this species is what is available on the Forum or in the references on the species Fact Sheet. As far as I know there have been no studies on reproduction and larval development in this species. It is just one of the vast majority of marine animals we know almost nothing about. The only information I think we know on it 'biology and natural history' is that it feeds on a plakinid sponge of the genus Oscarella  [see Jeff Goddard's message #14715] .

If I am wrong and you do find more information I would be grateful if you could let us know on the Forum. Otherwise I would go back to your lecturer and ask for a possible, rather than impossible, task.

Best wishes,
Bill Rudman
