The Aesculapian snake is one of the longest snakes in all of Europe.

The Aesculapian snake may seem large and intimidating, but in reality, this non-venomous species is fairly harmless. The old adage that it is more afraid of you than you are afraid of it happens to be very true in this particular case. This species should not be confused with the Aesculapian false coral snake, which belongs to an entirely separate genus and looks completely different.

4 Aesculapian Snake Amazing Facts

  • The name of this species is derived from Asclepius, the Greek god of healing. The snake often hid in temples dedicated to Asclepius and soon became exclusively associated with the god. In fact, the image of the Aesculapian snake wrapped around a rod is a common symbol of medicine and pharmacology today.
  • The mating season of the Aesculapian snake takes place between May and June. Rival males will wrestle each other for access to potential mates. When one male has won, it will begin a ritualized dance with the female. About four to six weeks later, she will lay her clutch of 10 eggs in a moist, warm spot such as hay piles, rotting wood, and old tree stumps.
  • The Aesculapian snake has the ability to climb straight up vertical surfaces. It has been found on roofs and even the top branches of trees.
  • The Aesculapian snake hibernates in its den for the winter. It also tries to avoid extreme heat.

Where to Find Aesculapian Snakes

The Aesculapian snake is endemic to forests, hills, and other habitats with plenty of cover. Its range extends across most of Southern Europe and small parts of Western Asia from the Atlantic coast to the Black Sea. It is not endemic to the United Kingdom, but many specimens apparently escaped from British zoos and established populations near Wales and London. The London population may have become extinct over time, but other populations have endured. There is a similar species known as the Italian Aesculapian snake that inhabits the southern Italian peninsula.

Aesculapian Snake Population & Conservation Status

According to the IUCN Red List, the Aesculapian snake is considered to be a species of least concern. While they do appear to be widespread and stable, population estimates are not currently known. Habitat loss from roads, farms, and buildings has traditionally been a threat to this species.

How to Identify Aesculapian Snakes: Appearance and Description

The Aesculapian snake has a long, slender body with smooth scales that give it a kind of metallic sheen. They have fairly small heads and round, dark pupils. Measuring up to 6.6 feet in size, it is among the longest snakes in all of Europe. The skin can come in various colors, including olive yellow, brownish-green, and even black, with regular patterns of white-edged scales along the sides and back. Juveniles, by contrast, have light green or brownish-green skin with darker patterns instead.

Aesculapian Snake: How Dangerous Are They?

Despite its large and intimidating size, the Aesculapian snake is not very dangerous at all. They do not produce any venom, and their bite isn’t strong enough to seriously damage human skin. If you are bitten by one of these snakes, then you should try to wash out the wound with soap to prevent an infection. It may be a good idea to seek medical care as well.

Aesculapian Snake Behavior and Humans

Aesculapian snakes are not very aggressive toward humans. They would prefer to run away and hide in their crevices when it comes into contact with a person.

Aesculapian snake FAQs (Frequently Asked Questions) 

Are Aesculapian snakes venomous?

The Aesculapian snake does not produce any venom.

How do Aesculapian snakes hunt?

Aesculapian snakes come out from their dens in the early morning or late afternoon to hunt for food. They generally use their speed and agility to surprise their unsuspecting prey. Like many snakes, they have an organ on the roof of the mouth that can interpret scent molecules from the air to help them locate prey. Without venom, they must hold the prey tight in their mouth or coils to prevent it from escaping.

Are Aesculapian snakes aggressive?

This species is not considered to be very aggressive at all. Their ability to hide in crevices and blend in with the environment helps them to evade potential predators. If they are seen, then they will try to run away and hide.

Where do Aesculapian snakes live?

The Aesculapian snake lives in fairly humid locations with plenty of rocks and vegetation to hide in. This includes forests and hills through Southern Europe and Western Asia. There have also been reports of escaped populations near London and Wales.

What do Aesculapian snakes eat?

The Aesculapian snake is carnivorous. Juveniles feed on lizards, insects, and small rodents. As they grow, the snakes begin to transition toward a diet heavy in rats, shrews, moles, and birds and their eggs.

What is the difference between an Aesculapian snake and the Aesculapian false coral snake?

The only real similarities are their size and perhaps some of their behaviors. Besides that, they are completely different. The Aesculapian false coral snake is venomous, lives in South America, and resembles a coral snake. It is also a member of a different genus (but the same family of Colubridae).

Can you keep Aesculapian snakes as pets?

Because of their fairly docile behavior, Aesculapian snakes could be kept as a pet without any fear of danger, but they are not really sold by many pet stores. Care can be a little difficult too. They need just the right temperature, humidity, and habitat size to thrive. If their care is not properly met, then they can easily suffer. This species can be fed on a fairly standard diet of rodents, just like many other types of snakes.

How long do Aesculapian snakes live?

The typical lifespan of the Aesculapian snake is about 25 to 30 years.
