The biologists and veterinarians Aquarium & Shark Lab In Hendersonville, North Carolinathey noticed swelling Charlotte last September. After running several tests and believing it was cancer, they discovered she was pregnant with multiple babies.

“We started noticing bite marks on Charlotte, but we saw other fish nibbling on her, so we moved the fish, but the bites persisted,” Jones said ABC13.

However, experts quickly refuted this theory. Kady Lyonsresearch assistant at Georgia Aquarium, stated that mating between sharks and manta rays is impossible. This is due to differences in size, anatomy and DNA.
