basal spiral striae. It
varies in color from transparent to opaque white but most show some
combination of transparent and opaque spiral bands that are independent
of the striae. The animal is translucent gray flecked with white. Some
have a few small, violet-brown spots on the lateral portions and
underside of the
head shield and/or the margins of the parapodia. Larger animals may
have faint golden-brown spots showing through the shell. It may be
distinguished from Aliculastrum debilis by the spiral
bands and the broader shell profile (resulting from fewer "stepped"
apical and basal striae).
Weinkauffia ukulele is a
moderately rare species known from ten animals found in open sand and Halimeda kanaloana beds at depths
of 9-11 m (30-36 ft). However, the number of dead shells found in sand
samples from up to 52 m (170 ft) suggests that it is more common in
deeper water. It's a nocturnal species that buries itself in sand
during the day. When handled,
freshly collected animals release a small amount of violet mucus in a
manner reminiscent of anaspideans. It lays a white, spherical,
sand-anchored egg mass that hatches in 2.5-3 days in the laboratory.
