Cylindrobulla sp. #1
Maximum size: 9 mm.
Identification:
This species has a thin, largely transparent shell with an aperture
that's constricted posteriorly. The animal is translucent-gray flecked
with opaque white.
Natural history:
Cylindrobulla sp.
#1 is a nocturnal, burrowing species. We've seen only three live
animals: one in a sand patch at < 1 m (< 3 ft) at a moderately
protected back-reef location and the other two in sand samples from Halimeda kanaloana beds obtained
from depths of 7-11 m (23-36 ft). However, several additional dead
shells found in Halimeda kanaloana
beds suggest that it may be more common in that habitat in deeper
water. It
probably feeds on the buried rhizomes of sand-dwelling Halimeda.
Distribution:
Maui.
Taxonomic notes:
It was first recorded in Hawaii from Black Rock, Maui by CP on Oct. 16, 1994.
