Around 100 tadpoles were seen mysteriously falling from the sky around 08:00 on the morning of June 7 over the Japanese city of Nanao.
Otsuki Yoshihiko, Professor Emeritus, Waseda University, believes the creatures might have been swept up from a river or lake by a gust of wind before being dumped on a parking lot in the community.
Another alternative, he suggests, is that the tadpoles were first scooped up by a heron or black-tailed gull. Such birds often eat tadpoles in paddy fields and herons have been known to spit out their meal when attacked by a crow.
However, one witness to this fortean event says there was no birds present in the sky at the time.
