The fox froze. Inches from his paws, frenzied, spawning carp writhed within the shallow water alongside a reservoir’s shore. In a sudden flash of motion, the fox dove nose-first into the water, rising with a big carp wriggling in his mouth.
In March 2016, two researchers in Spain watched as a male purple fox (Vulpes vulpes) stalked and caught 10 carp over a few hours. The occasion, described in a research revealed August 18 in Ecology, appears to be the primary recorded occasion of a fox fishing, the researchers say. The discovery makes purple foxes simply the second sort of canid — the group that features wolves and canines — recognized to hunt fish.

“Seeing the fox hunting carp one after another was incredible,” says ecologist Jorge Tobajas of the University of Córdoba. “We have been studying this species for years, but we never expected something like this.”
Tobajas and his colleague Francisco Díaz-Ruiz of the University of Málaga stumbled throughout the fishing fox whereas surveying a web site for a special mission. The fox first caught their consideration as a result of it didn’t instantly flee when it noticed the researchers. Seizing the chance, Tobajas and Díaz-Ruiz determined to cover close by and see what the fox was as much as.
Their curiosity become pleasure after the fox caught its first fish. “The most surprising thing was to see how the fox hunted many carp without making any mistakes,” Tobajas says. “This made us realize that it was surely not the first time he had done it.”
In March 2016, a male purple fox (Vulpes vulpes) in Spain was noticed grabbing carp throughout spring spawning season. The occasion appears to be the primary recorded occasion of a fox fishing. Foxes and wolves at the moment are the one canids recognized to fish.
Instead of instantly guzzling down the entire fish, the fox hid most of its catch and appeared to share a minimum of one fish with a feminine fox, presumably its mate.
Fish stays have been noticed within the scat of foxes earlier than. But scientists weren’t certain whether or not foxes had caught the fish themselves or had been merely scavenging useless fish. This analysis confirms that some foxes fish for his or her meals, says Thomas Gable, a wildlife ecologist on the University of Minnesota in Minneapolis who wasn’t concerned within the analysis.
“I would be shocked if this was the only fox to have learned how to fish,” Gable says.
Wolves residing on the Pacific coast of North America and in Minnesota are the one different canids recognized to fish (SN: 2/11/20). The proven fact that two canid species residing on separate continents each fish opens the chance that the habits is perhaps extra frequent than beforehand thought, Gable says.
For Tobajas, the fishing fox is an instance of how a lot scientists nonetheless don’t know in regards to the pure world, even for species that reside pretty shut with people. “The red fox is a very common species and is in many cases a bit hated,” he says. Foxes typically assault pets or livestock and are thought of a pest in lots of locations. But “observations like this show us that it a fascinating and very intelligent animal.”
