The term for a prominent feature of certain predators that enhances their hunting abilities is adaptation. These adaptations can include physical features, such as sharp claws, keen eyesight, or specialized teeth, that improve a predator's ability to catch and consume prey. Behavioral adaptations, such as stalking or ambushing techniques, also play a vital role in hunting success. These adaptations have evolved over time through natural selection, increasing the efficiency and effectiveness of predators in their ecological niches.
