Final answer:
Weasels use their canine teeth to kill their prey by piercing their vital organs, typically aiming for the neck or brain to quickly subdue their prey. This method is efficient and direct, unlike predation techniques that involve venom or constriction.
Step-by-step explanation:
Weasels typically kill their prey using a hunting technique that is different from other predators like snakes and lions. Unlike some snakes that use venom to immobilize their prey, or others that constrict their prey, weasels use their sharp canine teeth to kill.
The correct answer to the question of how weasels tend to kill their prey using their canine teeth is (d) Pierce vital organs. This method of killing is quick and efficient, allowing the weasel to subdue its prey effectively before eating it. Their hunting strategy involves biting the neck or skull of the prey, targeting the brain or other critical areas, causing instant death or severe damage.
Predation behaviors, where the predator directly kills its prey, can be observed in various animals. For instance, carnivores like the lion, shown in Figure 25.3, eat primarily meat and may use different methods to kill their prey.
