A 54-year-old New Jersey man expected a quiet day by the river. Instead, he became the victim of a rare wildlife attack. While fishing along the South Branch of the Raritan River near Clinton Township, the man noticed a beaver swimming nearby. At first, it seemed harmless—until it suddenly charged and bit him on the hand.
Startled and in pain, the man managed to fend off the attack and get out of the water. He was treated at Hunterdon Medical Center for lacerations to his hand, and fortunately, his injuries were not life-threatening. The beaver slipped back into the water and was not found.
When Beavers Bite: More Than Just Woodcutters

Beavers don’t have a reputation for being aggressive, but make no mistake—they can be fiercely territorial, especially during spring and early summer, when they are protecting their lodges and young kits.
Here’s why beavers may attack:
- They see people or pets as threats, especially near their nests or dams.
- They can act unpredictably if startled or cornered, both on land and in water.
- Though rare, some beaver attacks have been linked to rabies, which makes them unusually aggressive and unafraid of humans.
Their sharp, chisel-like teeth can slice through branches and skin easily. In this case, officials did not confirm rabies, but the victim is receiving preventative treatment as a precaution.
Staying Safe Around Beavers and Waterways

Beavers are a vital part of aquatic ecosystems, but it’s important to respect their space. If you spend time near rivers, lakes, or creeks—especially in areas known for beaver activity—here are some tips to stay safe:
- Keep your distance. If you see a beaver in or near the water, don’t approach.
- Watch for signs of lodges or dams. These are clear signs of a beaver’s home turf.
- Don’t let pets roam. Unleashed dogs may provoke a defensive response.
- Stay alert near the water’s edge. Beavers are strong swimmers and can move faster than expected.
- Back away slowly if approached. Don’t splash, scream, or run—stay calm and create space.
Even animals that seem peaceful from afar can be unpredictable up close.
A Rare But Real Risk
This unusual attack underscores the risks of underestimating wild animals, even those not typically viewed as dangerous. While beaver encounters are usually harmless, this event shows how quickly things can escalate when people enter their territory. Officials are continuing to monitor the area, and locals are encouraged to report any further sightings of aggressive wildlife.
What’s Next
Wildlife safety isn’t just about mountain lions or bears. Beavers—often seen as nature’s quiet engineers—can and will defend their space if provoked. Give them room, stay alert, and remember: wild animals don’t follow the same rules we do.
