Every crustacean has his day and for this particular one
it is All Hallows Day.
Ladies and gents, meet the Halloween crab!
This fine creature is a resident of Costa Rica, he and his family and friends live on the land in burrows they create.
However, they must remain close to water because if their lungs do not stay wet, they will cease to exist.
In my hunt for facts about these guys (and there wasn't much) I found that, apparently, people keep them as pets.
Which seems a little unecessary-who really needs rainforest crabs in their home anyway??
