giant otter - Pteronura brasiliensis - epaiva - 07-17-2017 Giant otter - Pteronura brasiliensis *This image is copyright of its original author *This image is copyright of its original author *This image is copyright of its original author *This image is copyright of its original author 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.

RE: giant otter - Pteronura brasiliensis - epaiva - 05-20-2018 Giant Otters vs Caiman RE: giant otter - Pteronura brasiliensis - epaiva - 08-16-2018 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.

RE: giant otter - Pteronura brasiliensis - Sanju - 03-18-2019 Like I said before, Otters are formidable... They killed a caiman coz it could be threat to their cubs. Imagine these in Southwestern China's ever green forests and wetlands or rivers. It's terrible... *This image is copyright of its original author The otter lived in a swamp surrounded by evergreen forest Siamogale melilutra, it weighed more than 50kg and was the size of a wolf. RE: giant otter - Pteronura brasiliensis - Sully - 07-18-2019 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.

RE: giant otter - Pteronura brasiliensis - Sanju - 06-03-2020 *This image is copyright of its original author 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. https://www.reddit.com/r/WTF/comments/1jzkpl/vicious_giant_otter_killed_and_ate_a_crocodile/ RE: giant otter - Pteronura brasiliensis - Dark Jaguar - 06-26-2020 credits: Larissa Ariel Lima *This image is copyright of its original author

RE: giant otter - Pteronura brasiliensis - Dark Jaguar - 11-13-2020 RE: giant otter - Pteronura brasiliensis - Styx38 - 02-22-2021 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. *This image is copyright of its original author http://alautreboutduboutdumonde.uniterre.com/229426/Pantanal+%2831+Octobre+-3+Novembre%29+.html RE: giant otter - Pteronura brasiliensis - Balam - 02-22-2021 (02-22-2021, 02:59 PM)Styx38 Wrote: Caiman seem pretty easy to kill by various animals. 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 *This image is copyright of its original author 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. |
