How slow is a stingrays metabolism and ovulation cycle?

Can it hold onto a fertilized egg for a long while?

I checked and looks like they may be able to hold onto sperm for a few years.

Painted turtles can hold sperms for up to 3 years and fertilize eggs from multiple clutches with saved sperm.

yeah thats what i was thinking hell look at cuddlefish they literally mate with a bunch of males, save their sperm separately in packets and then pick the 'best' to optimize the genetic quality. nature is wack. would be wild to learn another creature unlocked Parthenogenesis tho.

Cuddlefish are a fictional species from the game Subnautica. I think you mean cuttlefish.

well thats just ducking great. (obviously my autocorrect is attention seeking)

Poor touch starved autocorrect :(

I just kind of assumed that stingrays were capable of parthenogenesis.

Did a cursory search and this was the first result which put a dampener on the whole situation unfortunately.

What a roller coaster for the people caring for Charlotte. She has a lump that's probably a tumor, no it's eggs, no it's a baby, no it's a reproductive disease.

Sounds like they've perfected the process and us humans could learn a thing or two from them 😄

Eugenics has been pretty problematic for humans in the past.

[-] Tlaloc_Temporal@lemmy.ca 2 points 2 months ago

The problem with eugenics is other people having control over your reproduction. This is more control in the loins of the reproducers.

That's how human pregnancy works in the SF novel Ilium

Sounds like they don’t have time to cuddle.

Honey bees are another good example of this.

By late May and June 2024, medical testing and veterinary specialists confirmed Charlotte did not have embryos, but instead suffered from a rare and fatal reproductive disease that mimicked pregnancy on ultrasounds.
