📖 1. Overview
The Sidewinder is a small rattlesnake living in sandy terrain of warm deserts, featuring horn-like raised scales above its eyes.
🦴 2. Anatomy & Morphology
Because of the horn-shaped scales above its eyes, it is also called the horned rattlesnake, and its tail rattle gains a segment each time it sheds its skin. Females grow slightly larger than males.
🔍 3. Ecology & Behavior
Lizards make up more than half of its diet, along with rodents and birds. It uses sideways "sidewinding" movement to minimize contact with hot sand, and males travel an average of about 185 m per day in search of mates.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
