We present optical imaging and spectroscopy and H i imaging of the Virgo Cluster galaxy IC 3418, which is likely a “smoking gun” example of the transformation of a dwarf irregular into a dwarf elliptical galaxy by ram pressure stripping. IC 3418 has a spectacular 17 kpc length UV-bright tail comprised of knots, head–tail, and linear stellar features. The only Hα emission arises from a few H ii regions in the tail, the brightest of which are at the heads of head–tail UV sources whose tails point…
