The caretakers of the dogs that have made a home at the site of Chernobyl have spotted some canines with blue fur, a first at the disaster zone.
The group, called Dogs of Chernobyl, shared a video showing several packs of dogs with at least one completely blue.
'They were not blue last week. We do not know the reason, and we are attempting to catch them so we can find out what is happening,' the team shared in the video caption.
'Most likely, they’re getting into some sort of chemical.'
The organization, an affiliate of the non-profit Clean Futures Fund, added that while the color was alarming to see, the dogs appear to be 'very active and healthy.'
Since 2017, Dogs of Chernobyl has been caring for the roughly 700 dogs that live within the 18-square-mile exclusion zone.
The organization provides them with food and medical attention each year.
These dogs are the descendants of pets left behind when residents were evacuated following the 1986 Chernobyl nuclear disaster, one of the most catastrophic nuclear accidents in history.

While the team does not know what caused the blue coloring, social media users have made several suggestions in the comment sections of the videos posted to Instagram and TikTok.
'Those blue-tinged fur is a result of external contamination from chemicals, which can be washed off,' one TikToker shared.
Another posted in the comment section: 'Surprised these dogs are still fertile enough to breed, having been in contact with the contaminated area for so long.'
While these dogs appeared to be safe, scientists have been studying the animals living around the site since the disaster.
It began on April 26, 1986 with the explosion of one of the power plant's reactors and led to the largest release of radioactive material into the environment in human history.
Following the tragic event, humans were evacuated from Chernobyl and the surrounding areas to avoid the extreme levels of radiation. From then on, the site was known as the Chernobyl Exclusion Zone (CEZ).
Their absence allowed wildlife to flourish and thrive in the CEZ, which contains 11.28 millirem of radiation, six times the allowed exposure amount for human workers.
A study in 2024 found that the dogs had mutated to develop a new superpower - they are immune to radiation, heavy metals and pollution.

Scientists collected blood samples from 116 stray dogs living in the Chernobyl Exclusion Zone (CEZ), finding two different populations that were both genetically distinct from other dogs in the surrounding area.
This suggests they have adapted to withstand long-term exposure to this toxic environment and would explain why they have continued to thrive in the wasteland.
Norman J Kleiman, an environmental health scientist at Columbia University, led a team of researchers to investigate how living in this harsh environment impacted the dogs' genetics, as disasters that contaminate or destroy habitat can force wildlife to adapt to adverse environmental changes.
He and his colleagues collected blood samples from 116 'semi-feral' dogs, which were humanely captured around the Chernobyl Nuclear Power Plant and 10 miles away in Chernobyl City.
These samples were taken during sterilization and vaccination procedures conducted by the Clean Futures Fund Dogs of Chernobyl program in 2018 and 2019.
While the exact cause for the dogs turning blue is unknown, the team speculated that the animals rolled around in chemicals
The blood samples were then transported to the US for DNA extraction and analysis, which revealed the dogs' unique genetic makeup.
'Somehow, two small populations of dogs managed to survive in that highly toxic environment,' Kleiman said in a statement.
'In addition to classifying the population dynamics within these dogs . . . we took the first steps towards understanding how chronic exposure to multiple environmental hazards may have impacted these populations.'
He and his colleagues published their findings in the journal Canine Medicine and Genetics in March 2023.
Specifically, the researchers found nearly 400 'outlier loci,' or genomic locations that show behavior or patterns of variation that are extremely divergent from the rest of the genome.
Then, they identified 52 genes associated with these outlier loci that 'could be associated with exposure to the contamination of the environment at the Nuclear Power Plant,' the study states.
In other words, the dogs' contaminated environment caused them to develop genetic mutations that were passed down from generation to generation, ultimately driving their adaptation to the harsh conditions.
