What is one of the only crustaceans that live their entire lives on land?

This is not my round haven't got a question right yet. By the way I have never heard them called rolly pollies before.

They are also known as the wood louse. I like rollie-pollies better.

Always found them close to house and building foundations. Drip line from roof or gutters. Especially where there are a little cover for them.

luckycatfay, I think I may have called them rolly polly bugs when I was 5 years old.

Player Freewoman, apparently they aren't crustaceans.

also potato bugs?
