Liloa curta (Adams, 1850)

Maximum size: 18 mm
(extrapolated from shell length).
Identification:
This
species has a thin, transparent, cylindrical shell with fine,
evenly-spaced spiral striae. The animal is translucent-cream flecked
with white and violet-brown. It almost always has a cluster of
violet-brown flecks on top of its head behind the head shield. It may
be distinguished from Liloa cf. porcellana by that trait, by
its thinner shell and by the presence of spiral striae in the center of
the shell at all sizes.
Natural history: Liloa curta is a
common nocturnal species found in protected to exposed
patchy habitats and Halimeda
kanaloana beds from < 1 to 24 m (< 3 to 80 ft). It buries
itself in sand during the day. When disturbed, it can swim by flapping
its parapodia. It lays a spherical, white egg mass that hatches in
about three days in the laboratory.
Distribution: Maui, Oahu, Kauai, French Frigate Shoals, Laysan and Midway: widely
distributed in the Indo-Pacific.
Taxonomic notes:
This
species is listed as Haminoea
curta in Kay, 1979 (although the photo may be of Liloa cf. porcellana). It's also listed
as Atys curta in Severns, 2011.
