FfFfFfFF 42,392 Posted January 22 (edited) Two eagle rays have surprised New Zealand aquarists and bemused scientists by giving birth without any males in their tank. Nibble and Spot, both female and housed in the walk-through tunnel display at the SEA Life Kelly Tarlton’s Aquarium in Auckland, had pups on New Year’s Eve despite not having been near a male in two years. Andrew Christie, the curator of the aquarium, believed the most likely explanation is that the rays had stored sperm from their last encounter. [...] But in the case of the surprise eagle rays at Kelly Tarlton’s, Dutilloy believed the more likely explanation was parthenogenesis : a natural process of asexual reproduction, where an egg develops into an embryo without being fertilised. Compared to sharks, Dutilloy said sperm storage was relatively uncommon in rays, while parthenogenesis had been documented in spotted eagle rays – a close relative of Nibble and Spot’s species. https://www.theguardian.com/world/2021/jan/22/new-zealand-eagle-rays-astonish-aquarium-with-mystery-births Edited January 22 by FfFfFfFF ►► ► ► ► ► ► ► ► ► ►► ► ► ► ► ► ► ► ► ► ► ►► ► ► ► ► ► ► ► ► ► ► ► ► ► ► ►► ► ► ► ► ► ► ► ► 2 5 2 Quote Share Link to post Share on other sites Facebook Twitter

Sneaky Oliver 15,168 Posted January 22 But it's not completely abnormal. Some insects can 'give birth' without being fertilized too. A reverse Sneaky Oliver-ian expedition Quote Share Link to post Share on other sites Facebook Twitter

TasteLikeWhiskey 838 Posted January 22 For those that have shown interest - Have a look at this: It is literally one ancient, giant organism. Sometimes the line between reproduction and self-replication/cloning isn't so easily discernable. https://en.wikipedia.org/wiki/Pando_(tree) @FfFfFfFF @CubbyGaga @TSUNAMI @Sneaky Oliver Do not think I underestimate your great concern 2 1 Quote Share Link to post Share on other sites Facebook Twitter

Lady Papa 3,739 Posted January 22 (edited) They don't know if they hadn't encountered a male, those eagle rays could have received a "U up?" text in the middle of the night and nobody would have been the wiser Edited January 22 by Lady Papa Formerly known as LadyGoo Quote Share Link to post Share on other sites Facebook Twitter
