Description
Dr. John A. Zoidberg is a fictional character from the animated series Futurama. He is a Decapodian, a crustacean-like species of alien, who works as the staff doctor for Planet Express, despite his woeful understanding of human physiology and allusions to his questionable credentials.
His incompetence is aggravated by the fact that he believes himself to be an expert on human anatomy, and will blithely attempt to treat human patients as he would his own species. He has been shown as unable to tell the difference between robots and humans, believes food is digested in the heart, and that humans have multiple mouths and a dorsal fin.
Zoidberg is also poor, homeless, friendless, smelly, undignified, and repulsive, comically opposite the idea that a doctor stereotypically occupies a respectable, wealthy, and romantically desirable role. Regardless of these traits, Zoidberg is good-natured and means well, and will help the crew when the situation calls for it. Zoidberg also generally attempts to make himself look refined, successful and important in front of others, though this illusion is quickly dashed when pointed out.
