These little guys are usually around 1cm and have a flexible soft body (good for small amphibian/reptile snacks, not great for handling). They can't roll into a ball and have a faded/dusty look regardless of morphs. In the wild, they were first found enjoying the warmth and humidity of the Mediterranean and named in 1833. In nature and in captivity, they really seem to have a preference for hanging out under dead wood and logs. They can live for 2 years and breed easily, which makes them good for beginners especially with how adaptive they are. They're also extremely fast runners!
My experience
I own oreo crumbles but I think there's at least one white out in there that stands out from the rest. They definitely eat a lot but are shy and less likely to take it out of my fingers than dairy cows. I might try feeding them magnolia pods soon too since I have some in my yard. Personally I think they're just so easy and entertaining to watch that I'd prob recommend them over dairy cows. I also prefer the flatter-bodied speedy porcellio guys over the tubby (but cute) armadillidiums
