The 400-Million Year Old Fish That Refused To Die

he coelacanth is one of the greatest comeback stories in natural history. Thought to have gone extinct 66 million years ago, this ancient fish shocked the world when it was found alive and lurking off the coast of South Africa in 1938. But what is a coelacanth, and how has it survived five mass extinctions? In this video, we dive into the evolutionary journey of this living fossil—from its Devonian origins alongside armoured placoderms and early sharks, through the Permian extinction and the rise of the dinosaurs, all the way to its miraculous rediscovery in the 20th century. We'll explore what coelacanths were doing while everything else evolved, died, or moved on—and why they're still swimming in the deep while so many others have vanished. 🔹 What is a coelacanth? 🔹 How has it remained mostly unchanged for 400 million years? 🔹 Why did it disappear from the fossil record—and how did we find it again? 🔹 And most importantly: what can this ancient fish teach us about resilience, extinction, and human impact? If you’re fascinated by prehistoric life, deep-sea mysteries, or evolutionary oddities, this one’s for you.
