|"If it doesn't fit, can I have it?"|
Hermit crabs are usually polite. Hairy Harry, in back, waited patiently while Big Red thought it over, still holding onto the old shell, just in case. When BG decided that the new shell suited him perfectly, and wandered away, HH examined the old shell, realized that it was broken (on the far side, not visible here), and gave up.
No hard feelings.
The hermits are: Hairy Harry, a hairy hermit, Pagurus hirsutiusculus. They like smaller shells that enable them to run and climb easily: and Big Red, a grainy hand hermit, Pagurus granosimanus. They love a shell big enough to completely hide inside; they don't mind if it's heavy and awkward. They're in no hurry.
Hairy Harry is still in his old shell, waiting for me to provide another.
