Re: Aeolid? Janolus? Stiliger? from Sulawesi

Dear Bill,

Here's a photo of an animal that appears to be the same species from Hekili Point, Maui, Hawaii. It was 7 mm in length and autotomized a few of its longer dorsal cerata before it was photographed. I picked it up in an algae wash from a depth of less than 1 m in an area of mixed rubble/coral/sand on Nov. 23, 1997. It was only the second specimen we'd seen (the first was found under a rock by Pauline Fiene at a depth of about 12 m off Kihei, Maui). We've been tentatively listing it as a Stiliger but, after noticing the closely spaced eye spots while writing this, I suspect it may actually be a Costasiella. There's no sign of a crest between the rhinophores.

Best wishes,

Cory

Dear Cory,
Thanks for the input. A species of Costasiella is a most reasonable solution. A quick look at its radula would easily resolve the matter.
Best wishes,
Bill Rudman.
