American biologists have discovered an unusual fish that looks more like a giant carrot or a cartoon character than a familiar inhabitant of a body of water. Instead of the standard dark coloration, the burbot turned out to be bright yellow with an orange tint. Scientists have determined that the cause of the astonishing color was a rare genetic feature.
An unexpected find awaited specialists from the US Fish and Wildlife Service on 10 November 2026 during a routine survey of Oswego Harbor on Lake Ontario.
The biologists were conducting ordinary monitoring of the body of water, trying to detect invasive fish species. But instead of uninvited underwater guests, they came across a completely unexpected specimen — a burbot of unusually bright yellow-orange coloration.
The fish was so different from its relatives that the specialists immediately noticed it.
The find, made in October, was officially announced on 10 November.
The burbot that forgot what color it was supposed to be
The burbot (Lota lota) is a freshwater fish that usually has a brownish, greenish or dark brown coloration.
Such colors help it camouflage on the bottom of bodies of water, among stones and aquatic vegetation.
But the specimen discovered in Oswego looked completely different.
Its body had a rich yellow-orange hue, reminiscent of bright autumn foliage or a ripe carrot.
The wildlife service staff even joked that this fish could outshine the brightest colors of autumn.
The burbot looked as if nature had accidentally mixed up the palette and chosen a color for it from a completely different collection.
Why did the fish turn orange?
Scientists have established that the unusual coloration is linked to xanthochromism.
This is a rare genetic feature in which the normal formation of pigments is disrupted, and the animal's coloration acquires pronounced yellow or orange hues.
This phenomenon occurs in various animal species, but among wild fish it is considered especially rare.
According to the specialists, xanthochromism is observed significantly less often than albinism or melanism.
That is precisely why the find aroused such interest among biologists.
After all, discovering a fish of such an unusual color in its natural environment is a great stroke of luck for researchers.
The fish surprised scientists twice
But the unusual color turned out not to be the only surprise.
The very fact of the burbot's appearance in Oswego Harbor also caused astonishment.
The thing is that these fish prefer deep and cold sections of bodies of water, whereas the harbor is distinguished by different conditions.
In addition, the burbot population in Lake Ontario remains very low.
According to the US Fish and Wildlife Service, this is the first documented case of a burbot being discovered during scientific surveys of Oswego Harbor.
Previously, individual anglers had reported similar catches, but specialists had not recorded this fish in the course of their surveys.
Thus, the unusual specimen turned out to be a rarity for two reasons at once: because of its coloration and because of the place where it was found.
The unusual burbot was sent to veterinarians
After the catch, the specialists carefully examined the fish and noticed that it was severely emaciated.
The causes of its condition are still unknown.
Therefore, the burbot was handed over to the College of Veterinary Medicine at Cornell University for further study.
Scientists hope to find out what affected the health of the unusual specimen and what information it can provide about the state of the burbot population in the region.
Thus, the bright coloration not only made the fish famous but also helped draw attention to important scientific questions.
Nature can surprise better than any artist
The story of the unusual burbot once again shows how diverse the animal world can be.
Even well-studied species sometimes present specialists with astonishing surprises.
And although the bright coloration looks amusing, for the fish itself it may create additional difficulties in its natural environment, where camouflage helps it hide from predators and obtain food.
Now the specialists hope that the rare find will help them better understand the life of burbots and the reasons for the decline in their numbers in Lake Ontario.
For now, though, this story also has an amusing side: American scientists set out to look for uninvited inhabitants of the body of water, but found a fish that looks as if it were heading to an underwater carnival in a carrot costume.
And if there were a contest in the fish world for the most unusual color of the year, this bright orange burbot would surely be among the top contenders!
