Snails And Hermit Crabs – A Shell Story

Advertisement

Snails and Hermit Crabs both need bigger shells as they grow.

For the Hermit Crab, he just gets out of his now-too-small shell and finds a bigger one to move into.

For the Snail, he secretes a calcium carbonate from a gland that gets added to the edge of the current shell, thus growing the shell as it goes.

Two creatures. Same problem. Two very different solutions.

Now, I’m sure there’s a great metaphor in there somewhere about ‘life’ or ‘taking your shell with you as you grow’ or something…

but I’m not really interested in all that.

I just think it’s worth taking a moment to marvel at Mother Nature sometimes.
