Ercolania(?) sp. #9
Maximum size: 6 mm.
Identification:
This
species
has
a cream body with extensive green branches of the
digestive gland and numerous white flecks. It has many slender, though
tapering, cerata and the long rhinophores are obviously rolled (in
contrast to the blade-like rhinophores of Placida sp. #2). There's a
dark-green spot on the midline of the notum anterior to the
pericardium. The bases of the central cerata have swellings on their
anterior faces that contain branches of the digestive gland that lack
retained chloroplasts (giving them a white appearance).
Natural history:
Ercolania(?) sp.
#9
is known from three animals found on moderately exposed patch reefs and rubble from < 1 m (< 3 ft) to about 8 m (25 ft).
Distribution:
Maui.
Taxonomic notes:
This
species
may
belong in the genus Placida
rather than Ercolania. It was
first recorded in Hawaii from Canoe Beach, Kaanapali, Maui by PF on
Oct. 13, 2007.
