Where to see them

Did you know…

  • It is the only venomous snake native to the United Kingdom.

    From Adder

  • It is ovoviviparous, an adaptation that lets it survive in cold climates.

    From Adder

  • Many females do not breed until their eighth season.

    From Adder

  • It buries itself in the sand within seconds by vibrating its whole body, until only its eyes and horns show: it can spend days like that, invisible, waiting for prey to pass overhead.

    From Desert Horned Viper

  • It appears in Egyptian hieroglyphs as the consonantal sign for the letter F, one of the few animals of Ancient Egypt with a hieroglyph of its own in phonetic use.

    From Desert Horned Viper

  • The horns, each formed by a modified scale above the eye, appear to shield the eyes from sand, though there are hornless populations living in exactly the same environment.

    From Desert Horned Viper

  • Its skin, patterned in geometric blues and greens, makes it invisible in the leaf litter.

    From Rhinoceros Viper

  • It is probably the most colourful snake in Africa: a mosaic of purple, blue, green, red and yellow that, against the damp leaf litter of the forest floor, works as perfect camouflage despite looking impossible in the hand.
