Bitis cornuta is a venomous viper species found in certain rocky desert areas, mostly along the Atlantic coast of southern Africa. They have a characteristic tuft of horns above each eye.[3] Two subspecies are currently recognized, including the typical form described here.[5]

Description

Small and stout, growing to an average length of 30-50 cm. The maximum recorded length is 75 cm for a captive specimen.[4]

Geographic range

The coastal region of south-west Namibia through west and south-west Cape Province in South Africa. There are also a few isolated populations in eastern Cape Province. The type locality given is "Cap de Bonne-espérance" (Cape of Good Hope, South Africa). Actually, according to Patterson's itinerary the type was observed in coastal Namaqualand, on 1 September 1779.[1]

Habitat

Prefers rocky desert areas in dwarf succulent veld and mountain slopes in heathland vegetation.[3]

Behavior

Has a nervous disposition. When disturbed, it will hiss loudly and strike so energetically that most of its body is lifted off the ground in the process. However, it usually settles down in captivity.[3]

Subspecies

Species[1] Authority[1] Common name[4] Geographic range[4]
B. c. albanica Hewitt, 1937 Eastern many-horned adder South Africa (east and south Cape Province)
