On December 22, 1938, a young museum curator named Marjorie Courtenay-Latimer got a phone call from a fisherman in the South African port of East London. Captain Hendrik Goosen had pulled up a strange fish in his trawler net and thought she might want to see it. Marjorie hurried down to the docks, expecting nothing special. Instead, she found something incredible - a five-foot-long, steel-blue fish with thick, leg-like fins that almost looked like arms. She had never seen anything like it.
Marjorie sketched the fish and sent the drawing to a fish expert named Professor J.L.B. Smith. When his letter arrived, his hands shook. He recognized the creature immediately. It was a coelacanth, a fish that scientists had only ever seen as fossils. Coelacanths had supposedly gone extinct around 65 million years ago, around the same time as the dinosaurs. But here was one, freshly caught, with its weird lobed fins twitching on a dock. It was like finding a living T. rex.
The news exploded through the scientific world. The coelacanth turned out to be one of the closest living relatives to the ancient fish that first crawled out of the sea and became amphibians 380 million years ago. A second coelacanth was caught in 1952, and many more have been spotted since, mostly near the Comoros Islands and Indonesia. They live in deep underwater caves, can grow over six feet long, and give birth to live babies. Marjorie's curiosity that December afternoon proved that the ocean still has secrets, and that "extinct" sometimes just means "hiding really well."
