Phanerophthalmus cf. albocollaris
|Maximum size: 20 mm.
This species has a very small external shell that is much shorter than
body and is covered by the parapodia. The animal is pale violet,
flecked with darker violet and with white frosting on the posterior
lobes of the head shield. It is less slender than Phanerophthalmus smaragdinus
and the posterior margin of the head shield is
more deeply lobed than in that species.
cf. albocollaris is known from only two animals found in a rocky
area and a Halimeda kanaloana
bed between 7 and 19 m (23 and 62 ft). The mature animal showed a
nocturnal behavior pattern while held and buried itself in sand during
Maui: Phanerophthalmus albocollaris may be widely distributed in the Indo-Pacific.
