How To Identify Mandarin Rat Snakes: Appearance and Description

Mandarin rat snakes have a striking appearance. Their faces are striped black and yellow like a honey bee. The body is gray, brown, or reddish morphs, with large black diamonds or saddles. Within each black diamond is a smaller yellow diamond. Unlike other snakes, its bright colors are not due to genetic morphs.

Full grown Mandarin rat snakes typically grow to a length of 2.5 to 5 feet, with the majority of individuals remaining less than 4 feet in size. The longest full grown Mandarin rat snake on record topped out at 6 feet in size. The snakes stay slender throughout their lives, averaging 1 pound.

Unlike some other snake species, Mandarin rat snakes are not sexually dimorphic – males and females look the same. Size varies widely between individuals.

Mandarin Rat Snake Venom: How Dangerous Are They?

Mandarin rat snakes are not venomous. They are not considered dangerous. In fact, they are often kept as pets due to their docile temperament.

While lacking venomous fangs, the snakes do have teeth. If aggravated, they may bite, breaking the skin. A possible infection could result.

Mandarin Rat Snake Behavior and Humans

In the wild, Mandarin rat snakes are sky and secretive. They try to stay away from people. They are a diurnal species that are active during the day, primarily at dawn and dusk. They like to hide and hunt inside small rodent burrows.

If disturbed, the snake will attempt to flee. If this fails, it may hiss, spit, expel a pungent musk, or bite.

Breeding takes place in the spring. After breeding, the female typically lays three to 12 eggs. The eggs hatch after 48 to 55 days of incubation.

Sometimes, Mandarin rat snakes are kept in captivity. At one time, most Mandarin rat snakes on the market were wild-caught and often died in captivity. Now, breeding them in captivity is more common. A 20 to 30-gallon aquarium is sufficient for an adult snake. They can become accustomed to handling and are generally docile.
