The video is about giant otters, also known as Brazilian otters, that live in the Amazon River basin. These otters are part of the mustelid family and are known for their aggressive behavior, which helps them survive in their environment. They are skilled hunters and can eat up to 20% of their body weight in a day, mainly feeding on fish, snakes, caimans, and small rodents.
Giant otters are social animals that live in family groups, led by a mother otter. They are excellent swimmers and use their webbed hands to catch fish. They are also known to attack other predators, such as caimans and jaguars, if they feel threatened or if they are protecting their territory.
The video shows various clips of giant otters attacking these predators, including a caiman and a jaguar. It also shows how the otters work together as a team to hunt and defend themselves. Despite their aggressive behavior, giant otters are generally not aggressive towards humans and can coexist peacefully with them.
