Shamsher is pointing to a cluster of Lottia digitalis in the high intertidal area by peg 5b.

the artificial tidepool, this cluster of Lottia digitalis has been in the same place, to the left of the built stone wall since the building of the pool.

Behavior: These Limpets breath by drawing water from the left site over the gills out to the right site.

Description: Limpets are basically conical but they have an off-centre peak that curves over. Dark ridges extend from the peak to the edges of the shell. They grow to about 3 cm in diameter.
