Scientists find crocodile 'virgin birth' at Costa Rica zoo

Scientists have documented the first-known instance of a "virgin birth" by a crocodile, which had been living in isolation for 16 years at Costa Rican zoo, according to a study published Wednesday. The female American crocodile laid 14 eggs in 2018 within her enclosure, a not uncommon phenomenon among captive reptiles. The more puzzling fact, however, came after three months of incubation when one egg was found to contain a fully formed stillborn baby crocodile.
