Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future.

Giant otter - Pteronura brasiliensis

The giant otter or giant river otter (Pteronura brasiliensis) is a South American carnivorous mammal. It is the longest member of the Mustelidae, or weasel family, a globally successful group of predators, the giant otter It has the greatest body length of any species in the mustelid family, although the sea otter may be heavier. Males are between 1.5 and 1.7 m (4.9 and 5.6 ft) in length from head to tail and females between 1 and 1.5 m (3.3 and 4.9 ft). Weight 21 to 34 kg. Defence against intruding animals appears to be cooperative: while adult males typically lead in aggressive encounters, cases of alpha females guarding groups have been reported. One fight was directly observed in the Brazilian Pantanal in which three animals violently engaged a single individual near a range boundary.In another instance in Brazil, a carcass was found with clear indications of violent assault by other otters, including bites to the snout and genitals, an attack pattern similar to that exhibited by captive animals.The giant otter is an apex predator, and its population status reflects the overall health of riverine ecosystems. It feeds mainly on fish, including cichlids, characins (such as piranha), and catfish. One full-year study of giant otter scats in Amazonian Brazil found fish present in all fecal samples. Fish from the order Perciformes, particularly cichlids, were seen in 97% of scats, and Characiformes, such as characins, in 86%. Credits to Cesar Barrio-Amoros, Javier Mesa and Alan Highton.

Giant otters are known as River wolves, when they are in groups like they normally do they can confront and beat all predators they face in South America Jaguars, Caimans and Anacondas, they are great hunters that control the numbers of Piranhas.

Like I said before, Otters are formidable...

They killed a caiman coz it could be threat to their cubs.




River Otter vs Snapping Turtle. Mesmarized with these otter's abilities and strength. He just killed him!!!





Imagine these in Southwestern China's ever green forests and wetlands or rivers. It's terrible...

The otter lived in a swamp surrounded by evergreen forest

Siamogale melilutra, it weighed more than 50kg and was the size of a wolf.

The giant river otter, extinct in Argentina's Ibera wetlands for 70 years, returns! This week, beautiful Alondra arrived from quarantine to a pre-release pen on laguna Parana. Soon she'll swim free.

Quote:That is a giant river otter eating a caiman. Really cool picture, however this sort of thing isn't that uncommon. I worked on a team researching giant river otters in brazil and they don't give a fuck about anything. They will come right up to a human, which can be dangerous sometimes, and do whatever the hell they want. I had to remain motionless as one river otter mounted another and fucked it while never breaking eye-contact with me. These things eat piraña for breakfast. Don't fuck with giant river otters.

Caiman seem pretty easy to kill by various animals.

Might be because they are fish eaters, compared to the macropredatory lifestyle of Crocodiles and Alligators.

Still, the Otter killing this Crocodilian is quite an impressive feat.

It's rather obvious why you're trying to make caiman seem weak crocodilians compared to other crocodilians. Turns out you're wrong here as well:

After python, it is an otter's turn to kill and eat an alligator
The photographs taken in 2011 show an otter killing and devouring an alligator at the Lake Woodruff National Wildlife Refuge, Florida

The vast majority of crocodilians feast of fish, and that includes "macro predatory" (which all crocodilians are) like Nile or Saltwater crocodiles. The famous scenes of Nile crocodiles killing wildebeest and zebra only happen seasonally and are dependant on the ungulate migrations. Caiman from different species will eat whatever they can catch, this is the same case as all other crocodilians, and animals strong enough to kill them will do so if they can, which is the case for all other crocodilians as well.
