Two female eagle rays give birth at Auckland aquarium despite no contact with a male for two years
Two female eagle rays have given birth to pups at an aquarium despite having no contact with a male in two years. Nibble and Spot gave birth at the same time as each other on New Year's Eve without a male companion, intriguing aquarists and scientists. The two females reside in the Fish Tunnel display at SEA LIFE Kelly Tarlton's Aquarium in Auckland, New Zealand, which currently does not house a male eagle ray. Aquarium staff are trying to work out whether the pups were conceived through a process called parthenogenesis known as a 'virgin birth' or by sperm storage.
