Sitting it Out

Settled on a vertical face in the highest intertidal, Lottia digitalis sits out low tide clamped down tight. With the surf pounding just below, there is silence in these shells.


Note to arachnophiles: While preparing this post I noticed a red speck on the shell of the middle limpet. That’s a red spider mite (Neomolgus littoralis). Can you find it?
