Yes, the underlying story is real—but it is not a recent discovery, and many current posts attach the wrong image and the wrong explanation to it. In the early 1990s, a student in Ontario found an American toad whose eyes appeared to be positioned on the roof of its mouth. The student reportedly named the animal Gollum, and The Hamilton Spectator sent photographer Scott Gardner to document it.
The historical photograph has a credible publication trail, including reproduction in scientific and educational books. But at least one widely circulated modern image is an AI-generated Shutterstock illustration, not Gardner’s original photograph. The cause of the toad’s abnormality was never proven: a developmental error was considered plausible, while genetic, environmental, and parasite explanations remained unconfirmed.

The headline that a Canadian photographer found a toad with eyes in its mouth mixes a real case with several misleading updates:
- Real: An Ontario American toad was reported with a pair of eyes visible in the roof of its mouth.
- Old: The encounter is generally dated to about 1992, not to the date of a recent viral article.
- Misleading credit: A student found the toad; Scott Gardner photographed it after his newspaper sent him to the scene.
- Unresolved: The examining herpetologist could not determine whether the anomaly was genetic, environmental, or caused by anything else.
- Often mislabeled: A commonly reused recent image is AI-generated and should not be treated as archival evidence.
The most accurate summary is: real animal, real historical photograph, old case, unresolved cause, and misleading modern imagery.

Who found the toad?
According to the later account by Lewis I. Held Jr. in Animal Anomalies, a high-school student identified as Deidre found the unusual animal in her yard in Ontario. At first, she reportedly wondered whether the visible eyes belonged to another frog or toad that the animal had swallowed. She eventually realized that the eyes were attached to the roof of the toad’s own mouth.
Deidre contacted a local newspaper. The Hamilton Spectator then assigned photographer Scott Gardner to document the animal. That distinction matters: Gardner was the photographer, not the discoverer.
The location is securely identified only as Ontario in the accessible source trail. The Hamilton–Burlington area is often associated with the story, probably because Gardner worked for The Hamilton Spectator and the newspaper covered that region. However, the original newspaper article and its exact publication date have not been located in publicly searchable archives. Later retellings differ slightly over whether the encounter occurred in 1992 and was reported in 1993, or whether the entire episode should be dated to 1992.
For that reason, the careful wording is: the encounter is generally dated to 1992, with a later account referring to newspaper coverage in 1993, and it occurred somewhere in Ontario, reportedly in the Hamilton–Burlington area. Claims about a specific street, neighborhood, or “Burlington County” go beyond the available evidence.
Was it a frog or a toad?
It was described in the historical account as Bufo americanus, the older scientific name for the American toad. Modern taxonomy generally places the species under the name Anaxyrus americanus.
Calling it a frog is understandable in everyday language: toads are amphibians in the order Anura, the group commonly referred to as frogs and toads. But the more precise identification is an American toad, not an unidentified or newly discovered frog species.
What was unusual about Gollum’s eyes?
The eyes were reportedly attached to the roof of the mouth, in the palatal region. The skin on top of the head was intact where normal external eyes and eyelids would ordinarily be found. The account also says that the lenses were not covered by the normal layer of palatal tissue.
Those details are important because they distinguish the case from a normal toad temporarily moving its eyes during feeding. The eyes were not simply peeking through the throat for a moment. They appeared to be permanently displaced into an abnormal position.
The historical account describes the eyes as apparently functional in a limited sense: the toad seemed to react to movement only when it opened its mouth. Gardner reportedly had to wait for the animal to gape before he could photograph the eyes. That supports the idea that the eyes could detect at least some light or motion, but it does not prove that the toad had normal vision or normal visual acuity.

Can ordinary frogs really pull their eyes into their mouths?
Yes—but that normal ability does not explain this case. Many frogs and toads can retract their eyes inward during swallowing. The eyes move down into the oral cavity and help push food toward the esophagus. This unusual anatomy is one reason the photograph can look plausible even though Gollum’s condition was abnormal.

The researchers found that frogs could still swallow after the relevant nerves were severed, but they needed about 74% more swallows per cricket. The result demonstrated that eye retraction contributes mechanically to swallowing; it is not merely a visual reflex. The study is available through PubMed, with the full paper available as a Journal of Experimental Biology PDF.
The difference is straightforward:
- Normal frog or toad: The eyes develop in their usual positions in the skull and retract inward temporarily, especially during swallowing. Surrounding tissue covers and supports them.
- Gollum: The eyes appeared to have developed permanently in the oral-palatal area, while the external skin over the top of the head remained intact.
As Held notes, ordinary eye rotation or retraction cannot account for the reported anatomy.
How did the toad eat?
The animal’s survival was remarkable, but the available evidence does not show that it lived a completely normal life. Deidre reportedly tried feeding it worms, but it would eat only when food was placed directly into its mouth. Members of the newspaper crew apparently coaxed it to open its mouth by tapping its lips with insects.
Held described the toad as nearly blind, although that is a description from the historical account rather than the result of a modern clinical vision test. A toad that could detect movement only when its mouth was open would have faced obvious challenges finding prey, avoiding predators, and orienting itself.
Even so, the animal had survived in the wild for at least two years. It was described as a male about two inches long and at least two years old. Survival and the ability to swallow do not demonstrate normal health; they show that the anomaly was compatible with at least a limited form of feeding and life.
Did scientists solve the mystery?
No. The phrase “scientists were baffled” makes the case sound like a large, ongoing scientific investigation. The better-supported account is narrower: University of Guelph herpetologist Jim Bogart examined the toad but could not determine how the anomaly had developed.
Bogart reportedly suspected a severe developmental error in which the eyes formed or migrated in the wrong direction. He had seen many amphibian abnormalities but had not encountered this particular arrangement. He wanted to breed the toad to investigate whether the trait might be inherited, but Deidre declined to lend it to him.

After the animal died, the account says that Deidre also declined to donate its body for an autopsy. The publicly accessible record therefore does not include a genetic test, a preserved specimen, a modern imaging study, or a postmortem examination that could have settled the question.

The developmental explanation that may fit
Held’s discussion offers a plausible embryological model, not a confirmed diagnosis. During normal vertebrate development, the eye begins as an optic cup that grows outward from the developing forebrain. The optic cup normally reaches the side of the head, where it interacts with nearby tissue and helps induce the formation of the lens.
A hypothetical developmental misrouting could have sent the optic structures ventrally, toward the developing mouth, rather than laterally toward the normal eye sockets. If the optic cup reached tissue over the palate, its inductive signals might theoretically have caused lens tissue to form there. In that model, the eyes could be genuine eyes in an abnormal location rather than ordinary eyes that had merely moved during swallowing.
This is biologically plausible as a reconstruction of how such an anomaly might occur. It is not proof of what happened inside Gollum’s embryo. The actual trigger remains unknown.
Was a genetic mutation responsible?
Possibly, but there is no evidence strong enough to say so. A heritable developmental change was one possibility that breeding could have tested. Because the toad was not bred, researchers could not determine whether its offspring would have inherited the trait.

Terms such as macromutation may appear in popular retellings, but no molecular mutation was identified in this animal.
The safest description is an extreme developmental anomaly, possibly involving abnormal eye formation or migration, with genetic and environmental causes both left unconfirmed.
Could pesticides or another environmental exposure have caused it?
An environmental cause was also possible but never demonstrated. A chemical exposure during development, for example, might be considered when investigating an amphibian abnormality. However, the rarity of this particular condition made it difficult to connect it to a local contaminant, and the available account does not report an exposure investigation that identified a cause.

Only one other broadly comparable case was known in Held’s account. That scarcity does not rule out environmental factors, but it does mean that claims about pesticides should be presented as speculation rather than as a finding.

Online articles sometimes attribute the toad’s eyes to the trematode Ribeiroia ondatrae. That explanation appears to come from genuine research about amphibian deformities, but it has been extended beyond what the evidence supports.
Field and experimental research has linked Ribeiroia infections to severe amphibian limb malformations, including missing, extra, fused, or otherwise malformed limbs. Research has also investigated how the parasite can disrupt developing limb tissue and signaling pathways involving retinoic acid. The 2002 study is available through Ecological Monographs, and related experimental work is indexed at PubMed.
That research does not establish that a parasite caused Gollum’s eye displacement. The Ontario toad did not receive a reported parasite examination that demonstrated Ribeiroia infection, and its abnormality involved eye placement rather than the typical limb deformities associated with that parasite.
The accurate conclusion is: parasites can cause some amphibian malformations, but no direct evidence shows that a parasite caused this individual toad’s displaced eyes.

Was there another frog with an eye in its mouth?
Held’s account describes a 1996 case involving a leopard frog in Minnesota. That frog reportedly had one normal external eye and one internal eye hanging from the roof of its mouth on a stalk of tissue.
It was similar to Gollum’s case but not identical. Gollum was reported to have both eyes in the abnormal oral position, whereas the Minnesota frog had one normal eye and one internal eye. The cases suggest that extreme developmental abnormalities can occur, but they do not establish a common syndrome and should not be treated as evidence that the condition is frequent.

There are two separate image stories.
The historical Gardner photograph
The older photograph attributed to Scott Gardner has a credible provenance. It was taken for The Hamilton Spectator and later reproduced in publications including David Rollo’s 1995 book Phenotypes and Richard Dawkins’ 1996 popular-science book Climbing Mount Improbable. Held’s 2021 Animal Anomalies discusses the case and states that the photograph was used with Gardner’s permission. The accessible text of that book also records that Bogart personally examined the specimen.

That chain does not mean every image now labeled as the Ontario toad is genuine. It means the original case and an older photograph of the animal are supported by earlier documentation separate from today’s social-media posts.
The recent viral image
A highly realistic close-up used in recent articles and posts was traced to a Shutterstock listing labeled as AI-generated. An investigation by FactSeeker distinguished that image from the older Gardner photographs.
The AI image may be used as an illustration only if it is clearly labeled that way. It should not be presented as a scan of the original newspaper photograph or as visual proof that the case occurred.
For responsible coverage, publishers should use the Gardner photograph if they can confirm its rights and provenance, a permitted reproduction from a book, a clearly labeled normal American-toad photograph, or a diagram showing normal eye retraction versus permanent palatal displacement. The AI image should never be used without an explicit caption identifying it as synthetic.
What happened to Gollum?
The later account says that Deidre kept the toad as a pet. She declined the proposed breeding study, and after the animal died she reportedly declined to provide its body for autopsy.
The exact date and circumstances of Gollum’s death, as well as the final disposition of the body, are not established in the publicly accessible sources reviewed. That missing specimen is a central reason the case remains unresolved. Without the body, researchers could not examine the eye tissues, surrounding nerves, skull, palate, or developmental anatomy using modern methods.
The story is therefore not evidence of a new species, an evolutionary adaptation, or a beneficial trait. It is best understood as an isolated and severe developmental anomaly that happened to be documented by a newspaper photographer.

The Bottom Line
Bottom line: The Ontario toad with eyes in the roof of its mouth was a real early-1990s case, and Scott Gardner’s historical photograph is supported by later publications. A student—not the photographer—found the animal. Its cause was never established, and neither a genetic mutation nor Ribeiroia parasite infection has been proven. Treat recent AI-generated images and confident explanations as modern embellishments, not evidence.
