Caloria sp. #2

Maximum size: 10 mm.
Identification:
This species has a translucent-brown body with diffuse white patches on
top of the head and running along the midline of the notum. The cerata
are brown basally with white tips. The central cerata are enlarged and
coiled over the notum. The rhinophores have orange-brown tips and a
white medial band while the cephalic tentacles are tipped in white. It
can be distinguished from the similar appearing Phyllodesmium
sp. #2 by the diffuse, rather than sharp, boundaries to its white
patches and the orange-brown tips on its rhinophores.
Natural history:
Caloria sp. #2 is
a moderately common species found in moderately protected to
exposed rocky habitats and Halimeda
kanaloana beds at depths of 4-9 m (13-30 ft). Rarely, it can be
found in as little as 1 m (3 ft). It feeds on the
introduced hydroid Pennaria disticha
and shows a diurnal activity pattern in dishes.
Distribution:
Maui and Oahu: widely distributed in the Indo-Pacific.
Taxonomic notes:
First recorded in Hawaii by PF.
