Bullia digitalis

[1] These dominant scavengers are attracted by the scent of decaying animal matter from a considerable distance so that they converge from all directions to feed.

The ovate aperture is smooth, widened at the middle and strongly emarginated at its base.

The outer lip is simple, thin, sharp, and slightly effuse towards the middle.

[4] When the tide starts to rise, this snail emerges from the sand, spreads its large "foot" like a sail, and surfs up the beach in response to the smell of carrion.

[3] Often gathers in large numbers to feed on dead and stranded jellyfish and bluebottles.
