In an astounding case, researchers have found that an egg laid in 2018 by a female crocodile living alone in a Costa Rica zoo was not only fertile, it also contained genetics only from its mother.
In essence, the crocodile had just had a virgin birth.
In a paper published Wednesday from the Biology Letters journal, researchers said the unusual reproduction from the crocodile was the first evidence ever found in that species. The 18-year-old crocodile, which arrived at the Parque Reptilandia zoo in 2002, had been isolated from other crocodiles its entire life. The crocodile laid a cluster of 14 eggs, which is not unusual, but seven of those eggs appeared to be fertile. The fertile eggs were artificially incubated for another three months, but failed to hatch and were opened.
