Hermit Crabs and Bottle Caps

A few months ago I saw a video about hermit crabs of various sizes lining up in order of size to switch shells.  Those that outgrew their shells would move out and the next in line would take that shell.  Only the largest hermit crab had to find a new shell.  Ingenious.

That makes me sick.  How about you?

Please, please think twice before you discard any garbage, especially plastic, into anything but a proper receptacle. You can say that large manufacturer and car companies are ruining our environment. But remember that when it is you who are contributing to pollution.
