Eastern Copperhead (Agkistrodon contortrix) lives in eastern woodland edges across Eastern North America. Its conservation status is Least Concern.
Fascinating facts about the Eastern Copperhead
- Copperheads are true generalists: they hunt rodents, birds, amphibians, insects and even climb 5 m (16 ft) into shrubs to snatch cicadas. Juveniles use a bright yellow tail tip to lure frogs and lizards, a behavior called caudal luring, while adults rely on heat-sensing pits to strike warm-blooded prey with pinpoint accuracy.
- Southern copperhead venom contains the protein contortrostatin, which in mouse studies blocks cancer-cell growth and tumor spread. Though still experimental, this discovery shows the snake's bite could one day help develop anti-metastatic drugs, turning a feared predator into a potential medical ally.
- Copperheads can grow up to a massive 134.6 cm (53 in), yet most adults stay between 50-95 cm (20-37 in). Males rarely exceed 74-76 cm and weigh 101.5-343 g, while females top out at 60-66 cm and average 119.8 g.
- When threatened, copperheads can vibrate their tails faster than 40 times per second. This rapid vibration, combined with their habit of freezing, makes them nearly invisible on leaf litter.
- A newborn copperhead measures about 20 cm (8 in) and weighs roughly 10.6 g, about the weight of a small paperclip. Females can store sperm for up to a year. Litter sizes range from 1 to 21, with larger mothers typically producing more offspring.

About the Eastern Copperhead
In the dappled shadows of the forest floor, the Eastern Copperhead weaves a subtle path, its tawny coils blending seamlessly with the rust-hued leaves that carpet its domain. As it moves, the copperhead's body undulates in a sinuous rhythm, its scaly skin glistening like polished gemstones in the filtered light, allowing it to navigate the dense underbrush with ease. With eyes that gleam like dark jewels, this serpent surveys its surroundings, a master of stealth and patience, waiting for the perfect moment to strike.
