👉 The penguin weapon, also known as the "penguin claw" or "antipodal claw," is a specialized structure on the feet of certain penguin species, particularly those that waddle on ice or snow. This weapon consists of a sharp, curved claw located at the back of each foot, which can be used defensively to fend off predators or rivals. When threatened, penguins can extend this claw to deliver a powerful, sharp strike, making it an effective tool for protection in their harsh Antarctic and sub-Antarctic habitats.
