Beavers use scent marking to communicate with each other and to mark their territory. They have scent glands located on their tail, feet, and rump, and they deposit scent by rubbing these areas against objects. The scent acts as a warning to other beavers that the area is already claimed.
Teeth and claws
Beavers have strong teeth and claws that they use to defend themselves against predators. Their teeth are constantly growing, and they can grow up to 2 inches per year. Their claws are sharp and curved, and they can inflict serious injuries.
Slaps
Beavers are known for their powerful slaps. They can slap with their tail or with their paws. A beaver's slap can stun a predator or even knock it unconscious.
Swimming
Beavers are excellent swimmers, and they can use their tails to propel themselves through the water. They can also dive underwater and stay submerged for up to 15 minutes. This makes it difficult for predators to catch them.
Burrows
Beavers live in burrows, which provide them with protection from predators. Their burrows are typically located in the banks of rivers or streams, and they are built with multiple entrances and exits. This makes it difficult for predators to get inside the burrow.
Dams
Beavers build dams to create ponds, which provide them with a safe place to live and raise their young. Dams also help to control the flow of water, which can prevent flooding and create new habitat for other animals.
Other defenses
In addition to the defenses listed above, beavers also have a number of other adaptations that help them to survive in the wild. These include their thick fur, which helps to keep them warm in cold weather, and their ability to store fat, which helps them to survive through periods of food scarcity.
