Sand tiger shark embryos eat each other in the womb as a paternity strategy

Brutal!!!

Metal..

I was suppost to have a twin but nobody knows what happened to it. Now I know.....

Wow mama is a slut

Sharks are not mammals therefore they jaw eggs, the foetus gestate in those, not wombs.

now that's cannibalism on a completely new level.

The Sand Tigers send their regards

It's also cuz they don't get food so they eat echother

Daaaaaaaaaamn!
