The scaly-foot gastropod Chrysomallon squamiferum is a species of deep-sea hydrothermal-vent snail, a marine gastropod mollusc in the family Peltospiridae. This vent-endemic gastropod is known only from deep-sea hydrothermal vents in the Indian Ocean, where it has been found at depths of about 2,400–2,900 m. It differs greatly from other deep-sea gastropods, even the closely related neomphalines. It is widely distributed in the deep-sea hydrothermal vents of the Indian Ocean, which are around 2,780 metres in depth.
