Why are you called Anomura housing? Good question!
"Anomura" is the part of the species classification for a group of crustaceans that includes hermit crabs. That seemed like a pretty good name to us because our houses can be carried with you and expanded or upgraded as needed, just like the shell of a hermit crab.
Even more than that, because our houses can be reconfigured and modules can be brought in and out, if you are moving and needing to make a change to your living space, you could expand by acquiring more modules, or even just exchange elements of your house with other Anomura home-owners.
That process probably wouldn't look just like this, but you get the idea.
