| Crysomallon squamiferum Van Dover et al., 2001[1] |
Crysomallon squamiferum, common name the scaly-foot gastropod, is a species of sea snail, a deepwater marine gastropod mollusk in the family Neomphalidae.[citation needed]

Habitat
This species was discovered in 2001 on the bases of black smokers at the Kairei hydrothermal vent field, on the Central Indian Ridge, just north of the Rodrigues Triple Point; about 2420 meters below the surface.
Description
The snail's foot is armored with iron-mineral scales. It is protected by scale-shaped sclerites composed of the iron sulfides[2] greigite and pyrite.[3] No other animal is known to use iron sulfides in this way.
