It's been quite a while since I last posted - oops.
Today, over on old favourite, the Colossal blog, I saw these bizarre pieces of art interacting with nature, by Aki Inomata.
Using scanners, Inomata designed translucent plastic shells that would successfully and healthily accommodate hermit crabs (which constantly change shells as they grow), and added skyline sculpted features to them, before waiting for the hermits to move in. More here, as well as on her site.
A little while back, the BBC screened a great little documentary on the secret life of the rockpool, which included a segment on the hermit crab, and various experiments to show their intelligent selection of shells not only for their size, but their camouflage suitability. Here's a clip:
Excellent little creatures.
