Afrotyphlops schlegelii, commonly known as Schlegel's beaked blind snake or Schlegel's giant blind snake, is a species of snake in the family Typhlopidae. The species is endemic to eastern and southern Africa, and bears the distinction of being the world's largest typhlopid. It is harmless to humans and lives exclusively on a diet of termites.
The specific name, schlegelii, is in honor of GermanherpetologistHermann Schlegel.[1]
It is found in Angola, Botswana, the Democratic Republic of the Congo, Ethiopia, Kenya, Malawi, southern Mozambique, northern Namibia, Somalia, South Africa, southern Sudan, Swaziland, Tanzania, northern Uganda, Zambia, and Zimbabwe.[1]
Three distinct color phases are found: uniform, blotched, or striped.
Maximum recorded snout-vent length is 95 cm (37⅜ inches).
Scales arranged in 30-44 rows around the body. More than 300 scales in the vertebral row (maximum 623).[2]
Snout very prominent, with a sharp horizontal cutting edge, below which are located the nostrils. Rostral very large, extending as far back as the eyes. Portion of the rostral visible from below broader than long. Four upper labials. Nasal semidivided, the suture proceeding from the first upper labial. Preocular present, narrower than the nasal or the ocular, in contact with the second and third upper labials. Eyes distinct, located below the suture between the preocular and the ocular. Diameter of body 25 to 30 times in the total length. Tail broader than long, ending in a spine.[6]
It is fossorial, and very large individuals are found deep underground.[2]
This species is oviparous. A female usually lays 12-40 eggs, but very large individuals may lay as many as 60. The eggs, which are laid in late spring or summer, measure 20–22 mm long by 10-12mm wide (3/4-7/8 inch x 3/8-7/16 inch). The eggs hatch in 5–6 weeks.[2]
