Think of the egg-laying shark as the “lazy” parent—drop the eggs and bounce. The live-birth shark, though? That’s the helicopter parent of the ocean, carrying and nourishing its young for months.
If you’re feeling really impressed, consider the sand tiger shark. It’s the one that practices that sibling cannibalism we talked about. By the time it’s born, it’s already a tiny, ruthless survivor. Charming, right?
Meanwhile, the whale shark—the biggest fish in the sea—gives live birth to over 300 pups at once. Imagine that many baby sharks swimming out of you. No thanks.
