This distance is far beyond the previous verified record of around 650 feet (200 meters) for jaguars, according to the study authors.<\/p>\n<p>Jaguars (Panthera onca) are adept swimmers, often inhabiting rainforest regions threaded with rivers that frequently overflow their banks. They dive into the waters of their Central and South American range without hesitation \u2014 but these dips are normally brief and undertaken to capture prey such as caimans, fish and turtles.<\/p>\n<p id=\"28154140-8210-481f-b05e-cf2aa3943a87-2\">However, in a\u00a0<a class=\"hawk-link-parsed\" href=\"https:\/\/www.biorxiv.org\/content\/10.1101\/2025.09.05.674446v1.full.pdf\" target=\"_blank\" rel=\"noopener nofollow\" data-analytics-id=\"inline-link\" data-url=\"https:\/\/www.biorxiv.org\/content\/10.1101\/2025.09.05.674446v1.full.pdf\" data-hl-processed=\"none\" data-custom-tracking-id=\"8402562540316590775\" data-hawk-tracked=\"hawklinks\" data-google-interstitial=\"false\" data-mrf-recirculation=\"[Livescience] Article - Inline Link\" data-mrf-link=\"https:\/\/www.biorxiv.org\/content\/10.1101\/2025.09.05.674446v1.full.pdf\">paper<\/a>\u00a0that appeared Sept. 10 on the preprint server bioRxiv, which has not been peer-reviewed, scientists documented a jaguar swimming a much greater distance.<\/p>\n<p>Click below to see the paper:<\/p>\n<p><a href=\"https:\/\/www.biorxiv.org\/content\/10.1101\/2025.09.05.674446v1.full.pdf\" rel=\"nofollow noopener\" target=\"_blank\"><img loading=\"lazy\" data-recalc-dims=\"1\" decoding=\"async\" class=\"aligncenter wp-image-572877 size-full\" src=\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2025\/09\/Screen-Shot-2025-09-27-at-8.29.03-AM.png\" alt=\"\" width=\"642\" height=\"249\"  \/><\/a><\/p>\n<p>From the paper\u2019s abstract (bolding is mine):<\/p>\n<p>Here, we report the first confirmed long-distance swim by a jaguar (Panthera onca) across an artificial lake and discuss its implications for landscape connectivity. Camera traps around Serra da Mesa Reservoir (Central Brazil; 1,784 km\u00b2; 54.4 km\u00b3) photographed an adult male on the mainland and later on a forested island. Flank-pattern matching confirmed a 100% identity between records. Geodesic analysis identified two possible routes: a direct 2.48 km crossing or an alternative path involving a stepping-stone islet (1.06 km + 1.27 km). In the absence of evidence for use of the islet, we conservatively adopt the largest continuous water segment\u20141.27 km\u2014as the minimum distance swum. This represents nearly six times the longest previously verified jaguar swim (\u2248 200 m).<\/p>\n<p>Note that the article above gives the maximum and not the minimum distance!<\/p>\n<p>They knew it was the same leopard because the spots matched (this is the way we match female mallards across years, but using the bill pattern.

From the first article:<\/p>\n<p id=\"ecc48dd4-f12a-4f56-8ae5-ce47f362b7d9\">Even if the swim were undertaken over two journeys, this still represents a record-breaking distance for jaguars, the authors wrote.<\/p>\n<p>It is unclear why the jaguar made the swim. \u201cPrey in this region appears to be fairly evenly distributed, lead author Leandro Silveira, a biologist with the Jaguar Conservation Fund, told Live Science. \u201cNothing suggests the island has more prey, nor do the shorelines. We think he decided to explore a new area \u2014 more likely related to searching for females or territory than a lack of food.<\/p>\n<p>\u201cWe generally expect animals to seek the best cost-benefit option for movements, choosing narrower, less risky crossings,\u201d he added. \u201cThat\u2019s why this record was so surprising.\u201d<\/p>\n<p id=\"05b2a2a1-8dbd-4f06-a1f2-c3d8fb646345\">However,\u00a0<a class=\"hawk-link-parsed\" href=\"https:\/\/www.researchgate.net\/profile\/Fernando-Tortato\" target=\"_blank\" rel=\"noopener nofollow\" data-analytics-id=\"inline-link\" data-url=\"https:\/\/www.researchgate.net\/profile\/Fernando-Tortato\" data-hl-processed=\"none\" data-mrf-recirculation=\"[Livescience] Article - Inline Link\" data-custom-tracking-id=\"6759607457784510667\" data-hawk-tracked=\"hawklinks\" data-google-interstitial=\"false\" data-mrf-link=\"https:\/\/www.researchgate.net\/profile\/Fernando-Tortato\">Fernando Tortato<\/a>, a project coordinator for the big-cat conservation organization Panthera who wasn\u2019t involved with the paper or observations, notes that long swims probably are not unusual for jaguars.<\/p>\n<p>\u201cMost of the jaguar population is located in the Amazon basin,\u201d he told Live Science. \u201cThe main rivers there are in many places much larger than 1.6 kilometers. Some places are more than 10 kilometers.

From 1963 until her death in 1980, she was a familiar sight and helped keep the church mice at bay.<\/p>\n<p data-start=\"519\" data-end=\"664\">She often joined the congregation and was particularly close to the verger and his wife. She was known to curl up on the knees of parishioners.<\/p>\n<p data-start=\"666\" data-end=\"892\">When she died, local stonemason Peter Juggins felt she deserved a proper memorial. He carved a stone to mark her grave, just by the church entrance.
