Shell-boring parasitic worms are commonly found inside the shells of various pearl-producing mollusk species. Consequently, mollusk shells may exhibit elongated channels indicating the presence of such organisms. Recently, the author observed interesting parasite channel features inside an 8.25 mm natural saltwater pearl (see above) set in a brooch with other pearls and near-colorless stones.
Microscopic examination revealed a Y-shaped channel with numerous finer branches that likely formed as the parasite searched for a way out of the pearl. The channel opening was observed at the surface of the nacre, while the tunnel was located slightly beneath the nacre. This interesting feature matched the pearl’s internal structure, with a similarly Y-shaped structure visible in the X-ray image. Although such channels are often found in shells, they are rarer in pearls, and this channel’s unique shape and morphology are noteworthy.
