🦈 When the first shark appeared in the ocean — there wasn't a single tree on Earth. Not one. Zero.

Sharks have been around for about 450 million years. Trees — only 350 million.

They're older than Saturn's rings. Older than dinosaurs.
Dinosaurs appeared, took over the planet, and went extinct…

Sharks just kept swimming the whole time.

They've survived 5 mass extinctions — events that wiped out up to 96% of all life on the planet.

Evolution has barely touched them. Apparently, sharks have been "good enough" for the last half billion years.
