A Louisiana aquarium has a new star — and a mystery — on its hands after a baby shark was born in a habitat without any males.
The Shreveport Aquarium announced last week that Yoko the swell shark — named for "Onyoko," the Chumash word for shark — hatched on Jan. 3, about eight months after her egg was first discovered in a tank with only female inhabitants.
Not only that, it said, but its team "determined that the two female sharks present in the tank had not been in contact with a male in over 3 years."
"This situation is incredible and shows the resilience of this species," Greg Barrick, the aquarium's curator of live exhibits, said in the release. "It really proves that life ... uh ... finds a way."
Is it a miracle, a medical mystery or more? Scientists have two main theories.
