A species of sea snail, a marine gastropod mollusk in the
family Rostellariidae within the Stromboidea, the true conchs and
their allies. Most
specimens are found in the Philippines from tangle net fishing,
it is in the Philippines
protected species list.
It was in the 50 rare shells but, it
is hardly rare as it is a deep water species like most of the
species in the genus. There are two forms known, a lighter, smaller
shell and a larger, thicker shelled form.
Yoka star turban (Guildfordia yoka).
A species of deep-water sea
snail, a marine gastropod mollusk in the family Turbinidae,
the turban snails. The
size of the shell varies between 2.8 and 4.1 inches. The color
pattern of the shell varies from very light brownish to
purple-brown. Some specimens contain only six whorls instead of
seven as in the holotype. The upper whorls are smooth.
The base of the shell is less convex than the upper part.
Some specimens lack the rose-colored line around the umbilical
attractive specimens of marine wildlife, these gastropods are bought
and sold for their aesthetics. To protect local populations, the
catching and exporting of R. martinii has been forbidden by law
(Fisheries Administrative Order no. 208, s. 2001).
