The Immortal Jellyfish beats out that dinosaur that reproduced by parthenogenesis. They all had the exact same DNA as their parent, making them immortal on the genetic level. They are the only species ever discovered that only had females. Even all the eggs that have been studied were determined to be female. Some scientists speculate that they may have stimulated the reproductive cycle by same sex oral stimulation. That's why they were named *Lapsalotopus*. lol
