I found this under an intertidal rock encrusted with hydroids. This slug was also found at Mandavi under the rock in the same pool in which Eubranchus mandapamensis was found [message #22443 ].
Locality: Rock patch, Mandavi,Ratnagiri, 0.5 feet, Maharashtra, India, Arabian sea, 08 February 2009, below rock in the Rock pool, Intertidal with . Length: 8 mm. Photographer: Vishal Bhave.

This appears to be just another colour form of E. mandapamensis, in which the purplish band is very obvious and the fine brown spots all over the body are a lighter colour. If you look carefully at the rhinophores the rings, when present, are edged in white. Some of the rings seemed to be broken into a ring of a few white-tipped tubercles. This also suggest a link with Thompson's E. rubropunctatus, but in that species the tubercles on the cerata seem to be randomly arranged rather than in rings. As I said earlier, we still have a lot to learn about variability in this group of species.
