Volva volva

The Volva volva is a species of tropical Indo-Pacific present from the African coasts to Australia and western Pacific. Of white colour, pink or pale violet may exceed 14 cm. The animal lives nourishing of soft corals, chiefly the so-called whip corals. The foot is clear and elongated. A showy mimetic mantle permanently covers the shell with fanciful spots on clear background that have on the centre cylindrical tentacles of the same colour. They can be brown, more or less clear or reddish taken often, by dint of eating it, the colour of host for a perfect mimicry © Giuseppe Mazza
