Mark O'Shea has discovered a new species of worm eating snake, not in the field, but at Harvard University’s reptile collection. The New Guinea worm-eating snake was mislabeled in a specimen jar at the university when O'Shea found it during a research trip to Harvard’s Museum of Comparative Zoology.

The New Guinea Small-Eyed Snake


It hailed from Papua New Guinea, specifically from the Star Mountains, where it was found and killed by a villager in 1969.  

The snake, which O'Shea named Toxicocalamus ernstmayri in honor of German biologist Ernst Mayr, was highly venomous and fed mostly on worms. The snake at Harvard is the only known specimen in existence and is a female that measured about 3 feet in length. It is not known if the snake can still be found in the wild. The snake that it was initially thought to have been was the venomous New Guinea small-eyed snake, Micropechis ikaheka. It remained labeled as such until O'Shea made his discovery.

The full paper can be read on the Harvard University Museum of Comparative Zoology website.
