Coluber constrictor is one of the largest species of black snakes in Pennsylvania. They live for about ten years and can grow 36 to 60 inches (76.2cm to 152.4 cm) long.

Despite their ability to grow to incredible lengths, their bodies remain slim, allowing them to move at great speeds.

They are entirely black on their backs and stomachs. However, they have a small patch of white under their throat, and older coloration differs significantly from infantile coloration.

Northern Black Racers are gray with dark spots down their sides when they are young and brown spots down the middle of the back.

Hikers can find these snakes hiding under rocks and inside logs throughout Pennsylvania. It is not choosy about the type of habitat it prefers.

Snakes can be in various habitats, including fields, grasslands, woodlands, and rocky hills; they can even thrive along stream banks.

Northern Black Racers are also excellent climbers, so that you can find them in the branches of shrubs and trees.

The Northern Black Racer is not a threat to humans. However, this does not mean that you should attempt to pick up the snake; picking it up might be risky as it will try to bite concurrently.

So, snakes can cause bodily harm, but only if you threaten and harass them. Otherwise, it isn’t poisonous and won’t kill you.

Before going into attack mode, it will even try to slither away. If you push it, it will only feel the need to attack. These snakes are not constrictors, despite popular belief.

In addition, it behaves similarly to a rattlesnake. If you approach too closely, it will warn you by vibrating its tail against the ground, making a rattling sound.

Although this does not sound like a rattlesnake, inexperienced hikers may be perplexed.

These are the largest snakes on this list, measuring 40 to 101 inches (101.6 cm to 256.54 cm); however, unlike most snakes, which have rounded bellies, the belly of the Black Rat Snake is flat, so the sides meet at an angle.
