We have found these at Sombrero Island, Agahoto, Aqua Garden, Bethlehem and Caban Cove. 12mm.
The next three photos show three different individuals that all differed from our typical Thorunna furtiva in that they had distinct red lines running up the anterior and posterior sides of the rhinophores, rather than being just red all around the rhinophore tips. Although everything else looks pretty much the same between the two forms, it is possible there are two lookalike species here.
