Lottia persona

Lottia persona is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Lottiidae, one of the families of true limpets.

[1] L. persona is a large, moderately tall limpet growing to up to fifty millimetres long.

The apex is not central, being about one third of the way along the shell which is dark olive-green with fine white markings and has fine radial ribs, though these have often been smoothed down by erosion.

[2] L. persona is found on the North American Pacific coast from Alaska to central California.

It is a cryptic species, common to the high and mid-intertidal zones in sheltered rocky coasts.
