The ONLY VENOMOUS SNAKE Found in the United Kingdom!
Believe it or not, you can find ONE type of venomous snake in the United Kingdom.
But please don’t live in fear, thinking that you are going to be bitten. In general, snakes try to avoid any contact or interaction with people. As long as you leave them alone, you shouldn’t have any trouble!
Did you know that snakes are venomous, NOT poisonous? If you eat something that makes you sick, then it’s considered “poisonous.” If an animal, like a snake, delivers its toxins when it bites, it’s considered “venomous.”
Here is the ONLY kind of venomous snake in the United Kingdom!
- Vipera berus
Also known as the Common European Adder / Viper.
- Adults average around 55 cm (22 in) long.
- Color varies and can be brown, red, or light grey with a zigzag stripe on the back. But some individuals are entirely black.
- The head is fairly large and distinct and has a distinctive dark V or X on the back.
Adders are not considered an incredibly dangerous venomous snake in the United Kingdom.
Luckily, they are not very aggressive and rarely bite unless stepped on, picked up, or provoked. But if you are bitten, their venom is quite painful and causes swelling, internal hemorrhaging, and necrosis. While the venom can be lethal, deaths are incredibly rare. For example, about 200 people are bitten each year in Britain, however, there has only been 1 fatality since 1876!
Adder Range Map
Adders are found in many habitats, such as forest clearings, marshlands, heathlands, pastures with hedgerows, and even alpine meadows in the Alps. They mostly eat small mammals, but lizards, birds, and frogs are taken when available.
Because of their large distribution and a broad range of habitats, the population of Adders is currently not threatened. But their numbers are decreasing slightly due to habitat loss for agriculture and collecting them for the pet trade and venom extraction.
*If you come across this species, PLEASE DO NOT DISTURB! Venomous snakes are dangerous animals and should be left alone. The more you agitate them, the more likely you could get bitten. DO NOT RELY ON THIS ARTICLE to correctly identify a snake that has recently bitten you. If you have recently been bitten, GO DIRECTLY to the nearest hospital to get help and to determine if the snake is venomous.*
