Little pearl

 

 

Pear Marginella (Granulina margaritula), a very small marine snail —  the shell is only ~2-3 mm long.  Photographed in the low intertidal zone on 18 February 2023.

 

I posted a short video clip of this species several years ago, so if you'd like to see this snail in action, see "Shield up" from 6 December 2015.
