In an ordinary fishery, it recognizes a fish that disturbs the past

In 1938, a catch off the mouth of the Chalumna River in South Africa caught the attention of Marjorie Courtenay-Latimer. Curator at the East London Museum, she recognizes the unusualness of the fish. This look brings a fishing catch into a scientific story whose consequences will go far beyond the museum.

She reports the specimen to J. L. B. Smith, a passionate fish specialist. The identification links it to coelacanths, a group that scientists knew by its fossils and thought disappeared. The surprise does not come from a resurrected animal: a lineage had continued to live without its current existence being recognized by science.

The search for another specimen lasted for fourteen years, until a new capture in the Comoros in 1952. The first fish was not enough to reveal an entire population. Between catch and discovery, it took an essential gesture: to notice that this body deserved a different attention than that given to the rest of the fishing.
