I don't think it had ever been pregnant? I think I remember hearing it was cancer,

Not to say that some species can't self replicate, including some skates and rays I believe

I don't know the case here, but in case anyone is interested, animals that can self-impregnate are said to be parthenogenetic.

https://en.wikipedia.org/wiki/Parthenogenesis

(Most animal classes in the animal kingdom have parthenogenetic species, but there are no known cases in mammals that have not been artificially induced.)

It's weird, but it makes sense as a last ditch effort to bridge a population bottleneck. Just because we haven't witnessed something doesn't make it impossible.

I don't mean to suggest it's impossible. Clearly it is possible to artificially induce parthenogenesis in mammals because it has been done, although the offspring have not been healthy so far.

They killed her before stingray Jesus could come back and forgive the sins of all the stingrays. After they killed Steve Irwin, they’ve all been damned to Hell.

RIP Charlotte. I hope to hear an update with more details of your passing.
