Ultramarathon swimmer Andy Donaldson has achieved a remarkable world record by navigating the Ord River in Western Australia, a waterway notorious for its dense population of crocodiles. Experts estimate that approximately 5,500 crocodiles inhabit the river, meaning a predator could potentially be encountered every 100 meters. Despite these daunting conditions, Donaldson embarked on the 55-kilometer journey to push the boundaries of open-water swimming.
Donaldson completed the grueling distance in 11 hours and 51 minutes, shattering the previous record held by Simone Blazer, who finished the same course in over 16 hours in 2024. Starting his swim at 5:38 AM, the athlete faced not only the psychological pressure of the surrounding wildlife but also severe environmental challenges, including 34-degree heat and intense headwinds. His support team played a crucial role in ensuring his safety and maintaining his pace throughout the day.
At the starting line, Donaldson reportedly spotted a 2.5-meter crocodile, a sight that would deter most individuals. However, wildlife experts noted that the freshwater crocodiles found in this region are generally more timid than their saltwater counterparts and rarely pose a direct threat to humans unless provoked. Nevertheless, the swimmer admitted that the uncertainty of the environment kept him in a state of high alert for the duration of the marathon.
One of the most intense moments of the swim occurred when Donaldson felt an unidentified object underwater, leading to a momentary surge of adrenaline and fear. Despite the mental strain and the physical exhaustion of swimming against the wind, he reached the finish line at 5:29 PM without incident. This feat has been hailed as one of the most daring world records in marathon swimming, highlighting both extraordinary physical endurance and mental fortitude.

Ecological Shift: Golden Jackals Pro Projected to Inhabit 75% of the European Continent
Today in 06:53Once restricted mainly to the Balkans and the Black Sea coastal regions, golden jackals are rapidly expanding their footprint across Europe. According to a landmark study by an international research team published in Nature Ecology & Evolution, these adaptable predators could eventually inhabit up to 75% of the European continent—nearly a sixfold expansion from their historical range. Scientists arrived at these conclusions after monitoring nearly 9,000 sampling sites across multiple European nations.
Recent sightings and acoustic tracking confirm that jackals have established populations in the Czech Republic, the Baltic region, and even Scandinavia. The species thrives in areas with mild winters, mixed agricultural landscapes, and proximity to water sources. Regional climate warming has transformed previously uninhabitable northern areas into suitable habitats, while farming landscapes offer abundant food sources and coverage.
Biologists attribute this unprecedented expansion primarily to the historical decline of wolf populations, which naturally suppress jackal numbers and limit their movement. Smaller than wolves but slightly larger than foxes, jackals feed on small rodents, carrion, plants, and fruits. Their high ecological adaptability allows them to settle efficiently into newly colonized territories without human interference.
However, their entry into Western and Southern Europe, including countries like France and Spain, poses potential ecological consequences. Environmentalists warn that the arrival of jackals could disrupt local ecosystems and threaten endangered ground-nesting steppe birds and smaller wildlife across the Iberian Peninsula.
