Lamellaria sp. #6
 
Lamellaria sp. #6
Maximum size:  22 mm

Identification:  This is a burnt-orange species with a crown of triangular tubercles in the center of its dorsum. The dorsum and the underside of the mantle are decorated with faint dusky blotches. There are a few white flecks on the dorsum and the underside is peach-colored. Rarely, animals may be more elaborately mottled. Young animals may have faint medium-sized spots. (Note 1)

Natural history:  Lamellaria sp. #6 is known from five animals found in Halimeda kanaloana beds at 8.5-15 m (28-50 ft) and one found in a moderately exposed rocky habitat at about 5 m (15 ft). Rebecca Bicker reported that one animal "had a jerky movement as is moved forward."

Distribution:  Maui.

Taxonomic notes:  There is some uncertainty in separating this species from other listed species of Lamellaria. It was first recorded in Hawaii from Maalaea Bay, Maui by PF on June 1, 2007.

Observations and comments:

Note 1:  The apparently young animals included with this species have medium-sized circular spots. By itself that might suggest an affinity with Lamellaria sp. #3. However, one also has cloudy masses on the mid-dorsum while both lack light rings around the spots. Combined with the tendency in the genus for young animals to have spots that fade with maturity, those traits suggest they're more likely to belong with this species. However, the placement remains tentative.
