THE COMMON HERMIT-CRAB AND ITS ANEMONE MESbMAlE. 



In the photo the task of dragging the whelk-shell and its tall anemone appears a hopeless one, but as the anemone consists 

 mainly of ■water its weight in the \vater is not very great. Of old the anemone was thought to be a parasite; it is really a 



messmate.

THE HERMIT-CRAB AND ITS WORM MESSMATE. 



A beautiful, many-coloured sca-wofm. eight inches long, dwells in the upper part of the Hermit's house, and keeps it clean. 

 At meal-times it creeps alone; the Hermit's back, and helps itself to particles of f^ood.
