Anticlimax reinaudi is a minute sea snail, a marine gastropod mollusc in the family Tornidae.

[1] Anticlimax reinaudi has a very small (<1.5 mm), depressed shell, formed by 3 whorls of rapid growth, separated by a scarcely marked suture.

The ornamentation consists of spiral cords, ribs and axial striae.

It was found North-East of Malo Island, at depths of 13 m, on sand and dead corals.

[1] This species is named after Guy Reinaud, President of Pro-Natura International, coorganiser with MNHN of the "Our Planet Reviewed" expeditions, during which the species was discovered in 2006.
