Etymology
Origin of hedgehog
First recorded in 1400–50, hedgehog is from the late Middle English word heyghoge. See hedge, hog
Explanation
The hedgehog is a small nocturnal mammal that looks like a walking pincushion due to the collection of spiky quills that cover its furry body. It uses its sharp spines for defense by curling into a tight ball when threatened. Despite its prickly exterior, the hedgehog is known for its charming behavior and gentle nature. Its diet mainly consists of insects, making it helpful for pest control in gardens. Native to Europe, Asia, and Africa, the hedgehog digs burrows for shelter and has a keen sense of smell to find food. It also plays significant roles in various cultural stories and folklore, often symbolizing protection and strength. Hedgehogs have even become popular pets due to their unique and endearing qualities.
