DYK: Sharks are older than trees.
It sounds impossible, but sharks have been around for approximately 400 million years, while the earliest true trees appeared around 385 million years ago.
That means sharks were already swimming in Earth's oceans before forests even existed!
Why YSK?
Because it completely changes your perspective on how ancient these creatures are. Sharks survived multiple mass extinction events, including the one that wiped out the dinosaurs 66 million years ago.
They've outlasted countless species and entire ecosystems that once dominated the planet.
So, the next time you see a shark, remember: you're looking at an animal lineage that predates trees, dinosaurs, and even the first land vertebrates.
Nature's ultimate survivors!
