Eastern coachwhips are active during the day, especially in warmer weather. They prefer open habitat like pine flatwoods, scrub, grasslands, and sandy areas near coastlines. Coachwhips are fast-moving snakes, capable of reaching speeds over 7 mph for short bursts. This allows them to actively pursue lizard and rodent prey.
Coachwhips are oviparous, meaning they lay eggs rather than giving live birth. Females stay near their eggs until they hatch, defending them from potential predators. When encountered, coachwhips will often try to flee. But if threatened, they may flatten their head into an S-shape, vibrate their tail, strike, release musk and feces, or enact other defensive maneuvers.
