- "You seem malnourished. Are you suffering from internal parasites?"
- ―Zoidberg to Edna
- "Why, yes. Thanks for noticing."
Edna was a Decapodian woman who carried more eggs than any other female of her species; as such she wanted to mate with rock star. She liked to talk about things of little importance at great length. Her apartment is decorated like a fish tank.
Edna went to high school with Doctor Zoidberg and laughed at him because his face was covered in barnacles. During the mating frenzy in 3001, she was courted by Zoidberg, who was being coached on seducing Edna by Fry. When Edna found out that Fry was behind the "romantic" words, she cheats on Zoidberg and fell in love with Fry, and Zoidberg challenged Fry to Claw-Plach to settle the issue. Before the two finished their battle to the death, Edna and the Decapod Emperor left together and mated.
After the frenzy, due to the nature of Decapodian mating, Edna should have died, but during the unveiling of the final hole of Leo Wong's "Miniature" Golf Course, she makes an appearance in the stands and it is possible that she may have somehow survived. This is unverified however. The fact that many older females are seen in the series such as Zoidberg's mother implies that only the males die from the frenzy while the female become pregnant.
