Scaevatula is a genus of small predatory sea snails, marine gastropod mollusks in the family Clavatulidae.Bouchet, P. (2011). Scaevatula Gofas, 1990. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=405088 on 2011-08-27
Most gastropod species, and especially the marine species, have a dextral shell. The genus Scaevatula represents an exception to this rule, as the species are sinister. Within the family Clavatulidae, the extinct species Clavatula aralica (Luković, 1924) is the only other exception.Bonfitto, A., and M. Morassi. "A new sinistral turriform gastropod (Conoidea: Mangeliidae) from Taiwan." Zootaxa 3415.1 (2012): 63-68
