Yoko, the swell shark pup, hatched on 3 January after an egg was spotted by the US aquarium’s animal husbandry team eight months ago .
The two female sharks present in the tank had not been in contact with a male for more than three years .
This suggests either a process called parthenogenesis, a rare form of asexual reproduction, or delayed fertilisation may have occurred.
