Researchers say they made amazing discoveries on the Amazon River. But their evidence was not collected from water. I was able to see it from the coast. After about 219 hours of observation, they can check the male Amazon River dolphin (INIA GEOFFRENSIS), Also called botos, often roll to the back and urinate 3 feet or more in the air. Not random. The male botos seems to be peeing for the purpose.
For more than four years, the CETASIA RESEARCH GROUP team in Canada traveled to the Amazon river, where the dolphin river’s social interaction was careful. Researchers have written a total of 36 different instances of Botos, a male who decided to pee, while in a position that was not in the mold. Survey results published in recent research published in the journal Behavior processWe support an anecdoing story in rare cases of past bot actions.
“The aerial urination begins with the bot slowly located upside down, and the penis is exposed on the water and the urine flow is excreted in the air,” the team explained in his research.
In addition, another male dolphin was swimming about two -thirds of time nearby, and when it landed in water about 3 feet, it often approached the flow of urine. They were sometimes waiting, but in other examples, they pursued the pee trajectory using their nose or podium.
“We were really shocked because we had never seen it before.” New scientist January 31st.
Urine is a common communication tool used by many landleaders, such as dogs, bears, and cats. Although it can be seen much less in the aquatic environment, Araujovan and his colleagues provided some examples in their research. Dominated male African cicrid fish (Astatotilapia Burtoni) Interpret the urinary vein for both reproductive information and territorial information. Small claw crayfish (ASTACUS LEPTODACTYLUS) On the other hand, urinate as a sign of attack. However, in both cases, it is more related to peeing than what is actually in the pee itself.
According to researchers, this makes Boto behavior even more interesting. It is still unknown how the dolphins are interpreted the flow of urine, as the dolphin lacks the strong sense of both the smell and taste. The author of this research is assumed that the male Amazon River can rely on the hair of the podium to interpret the urinary composition of his fellow bot, such as hormone content that indicates physical health and social status. I did. a Previous research Bottle Northlookers have confirmed from Steven F. Austin State University in Texas (Texas)Tursiops is cut offUse their tongue to identify other critical drugs through the taste of urine. Knowing this, Amazon Botos may be engaged in similar activities.
But all of it has not yet explained why Botos is launching a pee in the air. Researchers acknowledged that “aerial urination is likely to be useful for social functions that exceed waste elimination,” but “stopped landing beyond social or communication functions for decisive reasons. ” Given that the ability to detect acoustic signals is increasing, the aerial urine may warn you to check it when you hit the dolphin.
Regardless of the actual reason, checking unique behavior among the Dolphins of the Amazon River has now revealed the potential of future research. More time and more peep -researchers may ultimately learn more about the complex social dynamics of aquatic mammals.
