VIDEO: Sea-Type Jaguars: Isolated Big Cats Have Taken To Eating Fish  – Baltimore, Maryland

Researchers have discovered a unique group of Jaguars deep in the wetlands of Brazil, who, unlike members of other species, survive primarily in the fishing industry and lead a very social life.

Jaguars are usually lonely, with the exception of mothers with Cubs, who mainly feed on deer and other mammals.

Nonetheless, a team of researchers and international scientists at Oregon State University appear to have found opposition in a group of Jaguars (Panthera onca) in the wetlands of northern Panthera, Brazil, northwest of São Paulo. Pantanal, which stretches across Paraguay and Bolivia, is the largest tropical wetland in the world.

Jaguar is a large cat breed and is the only living member of the genus Panthera native to the Americas. In 2016, the International Union for Conservation of Nature classified big cats as “near-threatened species”.

According to research, it was published in the journal EcologyThe observed jaguars behaved in opposition, with a diet consisting primarily of fish and reptiles, skillfully caught in flooded wetlands.

Motion sensor cameras have shown that big cats spend most of their time socializing. Often, they swim together or relax on the riverbank with members of the group.

Charlotte EricssonA PhD student at Oregon State University and the lead author of the paper, the findings establish that jaguars are lonely mammals and their social interactions are limited to courtship and territorial disputes. He said it was inconsistent with his belief.

The wetlands where Jaguars live are isolated and there are no roads or settlements in the area, so researchers did almost everything from the boat.

“Everything is boat-based. Obviously you can’t drive. And we can’t really walk because of the water and … a lot of jaguars,” Ericsson said.

Researchers had to be covered from head to toe to avoid being bitten by blood-sucking insects in flooded areas.

Tar LeviAn associate professor at Oregon State University said the area is home to an unusually high density of jaguars. Levi started the project in 2014 in collaboration with Brazilian researchers.

The study found that the jaguar diet consisted of 55% reptiles, 46% fish, and only 11% mammals.

“This finding shows that jaguars in the region have by far the highest aquatic diet and lowest mammalian consumption of any previously studied jaguar,” the researchers said. rice field.

“Even tigers in the Sundalvans mangrove forest in India, which may be the most comparable large family of cats in habitats similar to Jaguars in the Brazilian region, mainly consume terrestrial mammals.” They said.

Scientists believe that the density of jaguars in the region is very high due to the abundance and distribution of aquatic prey.

This abundance may have encouraged Jaguar to become more sociable and playful, as competition for food is less of a concern.

“If you have a lot of food around you, you don’t have to contend for it,” Ericsson said.

Researchers have recorded 80 independent social interactions between adult jaguars. One of the most striking moments was when two male Jaguars were playing together in front of the camera for more than 30 minutes.

“Usually, apex predators travel so large areas that cameras rarely show apex predators. Jaguars were the most frequently seen mammals on cameras, which is really unusual. “Ericsson said.
