A mild mannered graduate student until bitten by a radioactive king crab....
King crabs and their relatives are highly modified members of the superfamily Paguroidea (hermit crabs) and are placed in the family Lithodidae ('stone crabs' not to be confused with the famous Florida stone crab, unrelated). While most people are familiar the king crabs, this family contains a good number of smaller, really bizarre crabs that look downright alien (Google image search for Lithodes megacantha, Cryptolithodes, Lopholithodes, Phyllolithodes, and Hapalogaster). So I really like lithodid crabs, studying them, keeping them as pets, and eating them. Hence the name!

Elim Garak: "My dear Doctor, they're all true"
Doctor Bashir: "Even the lies?"
Elim Garak: "Especially the lies"
