Gyrineum natator: A potential indicator of imposex along the Indian coast

Imposex related studies have used neogastropods as sentinel organism. In this effort, we elucidate the potential of a mesogastropod, Gyrineum natator, for imposex monitoring on the central west coast of India. Observations were made with specimens collected from Mumbai (three stations), Ratnagiri (t...

Description
Summary:	Imposex related studies have used neogastropods as sentinel organism. In this effort, we elucidate the potential of a mesogastropod, Gyrineum natator, for imposex monitoring on the central west coast of India. Observations were made with specimens collected from Mumbai (three stations), Ratnagiri (two stations), Goa (one station) and Mangalore (one station). The analyzed populations at all four sites were affected by imposex. The six different stages of imposex in this organism are illustrated through schematic and scanning electron micrographs. In view of the anticipated ban on TBT based antifouling paints this baseline information can serve as an indicator for environmental monitoring in this region.
