- Imposex is the development of male features in female prosobranch gastropods, caused by organotin compounds. In the Mexican Pacific coast, imposex was observed in Plicopurpura pansa. This snail has been used by indigenous people to dye cotton and traditional fabric clothing. During 2010 and 2011, 5 habitats were visited along the coastline of Nayarit and Sinaloa, Mexico. At low tide, 675 snails were collected. Shell length, sex ratio and imposex incidence were measured. Imposex incidences were higher in the samples collected near harbor areas.
