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

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.

they literally mate with a bunch of males, save their sperm separately in packets and then pick the 'best' to optimize the genetic quality

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

Sounds like they don’t have time to cuddle.

Honey bees are another good example of this.
