Natural History Museums Are Teeming With Undiscovered Species

Ed Yong in The Atlantic:

1920In the darkness of the Akeley Hall of Mammals, swarms of kids gawk at beautifully staged dioramas of Africa’s wildlife. The stuffed safari, nestled in the American Museum of Natural History (AMNH) in New York, includes taxidermied leopards stalking a bush pig, preserved ostriches strutting in front of warthogs, and long-dead baboons cautiously considering a viper. In one corner, in a display marked “Upper Nile Region,” a lone hippo grazes next to a herd of lechwe, roan antelope, and a comically stern shoebill stork.

“This is my favorite one,” says Evon Hekkala, pointing to the display. “There’s a taxidermied crocodile tucked away down there.”

It takes a while to spot it and I have to crane my head to do so, but yes, there it is—a large crocodile, in the back, mouth agape, next to the hippo. It’s mostly hidden from view, and until recently, it was hidden from science, too.

Five years ago, scientists would have classified it as a Nile crocodile (Crocodylus niloticus)—one of the largest of the family, and among the most feared. But in 2011, after extracting DNA from this specimen and dozens of others, Hekkala proved that the iconic species is actually two species. One had been disguised as its more widespread cousin all this time. Hekkala called it Crocodylus suchus—the sacred crocodile. It’s the species in the diorama.
