Fascinating nature! Viral video shows how Amazon Dolphin can urinate in the air

A fascinating video of an Amazon river male dolphin urinating into the air has taken the internet by storm. The rare view, which was originally captured in March 2016, shows an Amazon river dolphin, known as the botos, urinating in the air, and one can also see another dolphin swimming nearby. The video captured from Brazil’s Tocantins River has resurfaced online, and the internet is going gaga over it.

"Nature is amazing," one netizen wrote on X. Another said, "Dolphins are wild, man." One X user wrote, "What if instead of dolphins they were called Dolphreakys and they peed on each other?" A second commented, "I wonder how people got the misconception that Dolphins were some pure animal." "What the Hell is wrong with dolphins? Seriously, just knock it off. Stop it," one said. Another user said, "Fascinating, but also the concept of river dolphins enjoying water sports is wild lmao." A third wrote, "It's a golden shower." "dolphins have always been weird," another opined.
"I swear dolphins could be characters in the boys," a comment on X reads. Another said, "it was only a matter of time before dolphins got kinky with watersports, LOL." "So I got a bit drunk last night, did I do anything embarrassing?" one said.

One netizen imagined the conversation between the dolphins and wrote, "Take a hike to the Amazon River- Home of Challenge Pissing! That's right! Challenge Pissing! How does it work? If you can piss six feet in the air straight up and not get wet, you get no down payment!" Another wrote, "i guess it really is water sports."
This brings us to the million-dollar question. So, do dolphins pee in the air?
Animals often use urination as a communication or to increase social bondng, however, it is unusual for aquatic mammals.

According to research published in 2025 in the journal Behavioural Processes, aerial urination "starts with a boto slowly positioning itself upside down, exposing its penis above water, and ejecting a stream of urine into the air."
"When a ‘receiver’ male is present, it either approaches the urine stream with its rostrum (sometimes pursuing it) or stays where the stream contacts the water," the author says, and adds that the receiver individual actively seeks the urine stream with its rostrum.
"Bristles in the rostrum may serve to detect chemicals in the urine of conspecifics." Interestingly in the resurfaced video, one can see another dolphin near the urine stream of the peeing dolphin.
