Virgin Crocodile Reproduces Asexually in First for Species

  • A female crocodile in Costa Rica gave birth to genetically identical offspring without mating.
  • The parthenogenesis occured when a polar body fused with an egg, creating an embryo with the necessary chromosomes.
  • Parthenogenesis has been observed in other reptiles, birds, and animals but never before in crocodiles.
  • The discovery suggests parthenogenesis may have also occurred in ancient crocodilians like dinosaurs and pterosaurs.
  • Two female California condors also successfully hatched eggs without mating, exhibiting facultative parthenogenesis.
