young, 4 mm
Cylindrobulla sp. #1
|Maximum size: 9 mm.
This species has a thin, largely transparent shell with an aperture
that's constricted posteriorly. The animal is translucent-gray flecked
with opaque white.
#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
probably feeds on the buried rhizomes of sand-dwelling Halimeda.
It was first recorded in Hawaii from Black Rock, Maui by CP on Oct. 16, 1994.
