Scientists recently took to Twitter to puzzle over an unusual sight captured by a biologist in photos and video: a toad that had no face.
The toad, a fully grown adult, had a healthy-looking body and legs, but it was entirely lacking eyes, a nose, jaws and a tongue. Instead of a face, it had only a stump covered by smooth tissue and a small opening where its mouth used to be, according to herpetologist Jill Fleming, who discovered the toad.
It "kept hopping into things," Fleming tweeted.

Fleming spotted the unfortunate creature — an American toad (Anaxyrus americanus) — in April 2016 in a state forest in Connecticut, where she was conducting research on Eastern red-spotted newts, she told Live Science in an email. [In Photos: The World's Freakiest Looking Animals]
"We sat down on a log to process the samples, and the toad kept running into our feet. When we looked closer, we realized it had no face!" Fleming wrote in the email.
Fleming tweeted a photo of the faceless toad on Feb. 27; she suggested that it had probably recently emerged from brumation — reptile hibernation — looking this way. In the tweet, she invited her fellow herpetologists, or "herp Twitter," to consider what might have caused the animal's highly unusual condition.
Video of the toad showed it tentatively stepping over the forest floor, and there was no sign of a wound where its face presumably once was. However, Fleming explained that its facelessness was probably not the result of a genetic mutation, as the toad was missing a lot of the anatomy required for feeding and couldn't have made it to adulthood without being able to hunt.
Pre-hibernation fat reserves padding the toad's body were likely helping to keep the creature alive, Caruso added. But the hapless toad's chances of surviving in this condition were "really poor," and it likely wouldn't have lasted for very long after running into the researchers, Fleming told Live Science.
"It probably couldn't eat in this condition. Plus, it kept bumping into us, so if we were its natural predators, it would have been eaten very quickly," she said.
