THE WONDERS OF THE SHORE, 199 
in the muddy sand which fills the lower cracks of 
rocks. 
But you will want more than these anemones, 
both for your own amusement, and for the health of 
your tank. Microscopic animals will breed, and will 
also die; and you need for them some such scavenger. 
as our poor friend Squinado, to whom you were 
introduced a few pages back. Turn, then, a few 
stones which lie piled on each other at extreme 
low-water mark, and five minutes’ search will give © 
you the very animal you want,—a little crab, of a 
dingy russet above, and on the under side lke 
smooth porcelain. His back is quite flat, and so are 
his large angular fringed claws, which, when he folds 
them up, lie in the same plane with his shell, and 
fit neatly into its edges. Compact little rogue that 
he is, made especially for siding in and out of 
cracks and crannies, he carries with him such an 
apparatus of combs and brushes as Isidor or Floris 
never dreamed of; with which he sweeps out of 
the sea-water at every moment shoals of minute 
animalcules, and sucks them into his tiny month.
