Cribrarula taitae (Burgess, 1993)
Tait's cowry, 18.5mm
This is probably the most rarely
found cowry at Kwajalein. Only two specimens are known, both collected as empty
shells at the edge of the oceanside dropoff at a depth of about 6-7m, and both
in the late 1960s or early 1970s. It has not been seen since. It resembles the
much more common Cribrarula cribraria
but has dark spots around the edge of the base where C. cribraria
does not. The Kwajalein specimens resemble the Hawaiian Cribrarula
gaskoinii, even more closely, we think, than it does to photos we have
seen of C. taitae. It is at least slightly possible that these two
specimens represented a chance settling of C. gaskoinii larvae from
Hawaii. While studying nudibranchs at Enewetak Atoll in the northern Marshalls,
one or two specimens were found of a couple of different nudibranch species
thought to be restricted to Hawaii, as is C. gaskoinii. It could be
that an occasional veliger larva makes it to the Marshalls from Hawaii, but
never enough to start a population. However, at this time, we assume it is C.
taitae, extending that species' known range into the Marshalls from eastern
Melanesia and western Polynesia.
