Information on Tantulum elegans

August 31, 2006
From: Sarsha Lall

Could you please give me the taxonomic classification of the sea slug Tantulum elegans, giving especially the Family to which it belongs.

The only reference that I could find on this forum about Tantulum elegans is that it is found in a swamp in St. Vincent. Is this reference related to the work done by Harrison and Rankin 1976?
Do you know if it has been recorded anywhere else in the Caribbean?

With thanks,

Dear Sarsha,
Have a look at my comments to message #16865 and Michael Schrödl's message [#15744]. I am pretty sure the reference is Rankin, 1979. Michael Schrödl may be able to give you more up to date information, but these microscopic animals are difficult to find and difficult to 'dissect', so we still have much to learn about their biology, natural history and their phylogenetic relationships. Until that is done 'families' and even 'genera' are a bit tentative.

Best wishes,
