Average Length: 50 cm. Names in other languages
Afrikaans: Gewone nagadder.
Look for:
  • A V-shaped marking on the neck behind the head


Distribution


Venom Type: Cytotoxic. Venom, although producing normal blood poison symptoms, is seldom fatal if adequate first aid treatment is administered within reasonable time


First Aid

Immobilise and reassure victim, who must lie down and be kept as quiet as possible. Apply pressure bandage immediately, see First-aid procedure; immobilise limb with a splint to reduce spread of venom. Loosen, but do not remove bandage if there is severe swelling. Take victim to hospital as soon as possible.

Habits

This snake is docile and will move off if given choice. When molested it will react violently, hissing noisily, flattening the neck and striking repeatedly. They are usually found in stone piles, termite nests or mammal burrows.  If provoked it will inflate its body with air, coil its body and hiss, striking at same time. It has long venom glands extending backwards into neck region. The V on the back of the neck is characteristic, mimicked by the harmless Egg Eater

Food

Toads and frogs.

Reproduction

Oviparous. Lays 12-26 eggs in summer which hatch after 75-80 days. Young 130-160 mm.

Enemies

Other snakes, leguaans and predatory birds.

Habitat

Favours damp moist savanna, lowland forest; seeks refuge in old termite mounds, under logs and building rubble.
