What is the oldest thing in the ocean?
Sponge. No one’s exactly sure how old the sponge is, but scientists do know that one species is at least 760 million years old. That’s old enough to make them the longest-existing marine life species still around today!

When did Megalodon go extinct?
about 3.5 million years ago
Megalodons are extinct. They died out about 3.5 million years ago. And scientists know this because, once again, they looked at the teeth. All sharks – including megalodons – produce and ultimately lose tens of thousands of teeth throughout their lives.
Do sharks fall asleep?
Sharks can sleep, and often opt to keep their eyes open while they do, according to new research published in Biology Letters. Because some sharks must swim constantly to keep oxygen-rich water flowing over their gills, it has long been rumored that they don’t snooze at all.
