Calliostoma anseeuwi is a species of medium-sized deepwater sea snail, a marine gastropod mollusc in the family Calliostomatidae distinguished by its biconical teleoconch with 9–11 sharply carinated whorls adorned with alternating gold and violet spiral bands.[2] This Philippine endemic species inhabits carbonate slopes at 180–400 m depths in the Verde Island Passage biodiversity hotspot, where it grazes on foraminiferan biofilms. The holotype (NMP 039154) was collected during the AURORA 2005 expedition, named in honor of malacologist Philippe Anseeuw. Its restricted distribution and specialized deep-reef habitat qualify it as a potential indicator species for mesophotic zone conservation.[3]
