Zoidberg is a lobster-like alien from the planet Decapod 10, and the neurotic staff physician of Planet Express. Although he claims to be an expert on humans, his knowledge of human anatomy and physiology is woefully inaccurate. Zoidberg's expertise seems to be with extra-terrestrial creatures. Homeless and penniless, he lives in the dumpster behind Planet Express. Although Zoidberg is depicted as being Professor Farnsworth's long-time friend he is held in contempt by everyone on the crew.
