Crabs

Scuttle, scuttle.  Rocks scuttle about.  Instantly I realise they were hermit crabs.  Overhead there were pelicans and frigate birds.  The water was crystal clear and the waves crashed against the shore.  The breeze blew against my face keeping it cool.  I see a mottled purple, yellowy, grey body with bumpy arms and two pincers.  A crab.  I saw another crab with navy blue pincers and a dark green body.
