Officials at Uozu Aquarium in Toyama Prefecture are scratching their heads after finding twin baby banded houndsharks in a tank that only held three female adults.

The female twins, named Mana and Kana after well-known twin actresses, were found in the aquarium’s tank on May 8, the officials said. They said it might be a case of parthenogenesis, a type of asexual reproduction in which offspring develop from unfertilized eggs. Although parthenogenesis has been observed in other shark species, the case in the city of Uozu, if confirmed, would be the first ever for banded houndsharks, they said.
