Sometimes opposites attract. And sometimes it only seems that way. In February 2024, a female stingray at an aquarium in North Carolina started showing signs of pregnancy while sharing her tank with several male sharks, spawning theories that the male sharks had impregnated her.
But some scientists state that these theories are as improbable as they sound: No matter the circumstances, they say, sharks cannot impregnate stingrays.
So, why were some people so convinced that a stingray and a shark mated, and why are some scientists so sure that that isn’t the case?
