Headline: UNCAPTIONED: Aquarium Surprised By 'Virgin Birth' Of Swell Shark In All-Female Tank
Caption: A Louisiana aquarium has been left stunned by a 'virgin birth' in its shark exhibit. Baby swell shark Yokowas born in an all-female tank at Shreveport Aquarium. Experts believe Yoko's birth is due to parthenogenesis, a rare form of asexual reproduction. While parthenogenesis occurs in some species, the exact triggers remain unclear. Another possibility is that Yoko's mother stored sperm for years before fertilisation. Scientists will conduct tests in the coming months to determine how Yoko was conceived. Her name comes from the Native American Chumash word for 'shark'. Sharks born through parthenogenesis often face challenges and shorter lifespans. Regardless of her lifespan, Yoko is contributing to shark conservation research.
