Which predator is described as a skilled climber that hunts porcupines by accessing the underside where there are no quills?

• A. Fisher
• B. Bobcat
• C. Owl
• D. Raccoon

Answer: (A)

Porcupines defend themselves with sharp quills, so the predator that succeeds must be able to climb well and find a way to reach a vulnerable area. A fisher is a highly skilled climber and versatile hunter, famous for preying on porcupines by pursuing them into trees or tight spots and attacking the ventral underside where quills are less protective. Its combination of agility, climbing ability, and targeting the unprotected underside makes it the best fit for this description. While other predators on the list may encounter porcupines, they are not as specialized or effective at exploiting the underside in a climbing context.
