Sidewinding is a type of locomotion unique to snakes, used to move across loose or slippery substrates. It is most often used by the Saharan horned viper, Cerastes cerastes , the Mojave sidewinder rattlesnake , Crotalus cerastes , and the Namib desert sidewinding adder, Bitis peringueyi , to move across loose desert sands, and also by ...
The snakes can mate for several hours, and if one of the snakes decides to move, the other is dragged along. Females might mate with several males in a season. Females give birth to five to 18 young in late summer to early fall. The young are born 6-8 inches long. The birth takes only 2–3 hours altogether.
“The size of these magnificent creatures was incredible," Fry said in a news release earlier this month. "One female anaconda we encountered measured an astounding 6.3 meters (20.8 feet) long."
The species A. branchi, like other species of its genus, is notable for its unusual skull, allowing it to stab sideways with a fang sticking out of the corner of its mouth. [4] A. branchi has morphological similarities to A. reticulata , but is distinguished by having 19 rows of dorsal scales at midbody.
As a result of all these factors, cases of fatal bites of this snake are very rare. There were only 2–3 recorded fatal cases since its discovery in 1950. [15] [13] The latest death happened on 2002 when a man tried to capture a snake near his house on the border of the Judean Desert. [16]
The desert cobra is highly venomous. The subcutaneous LD 50 for the venom of W. aegyptia is 0.4 mg/kg. For comparison, the Indian cobra's (Naja naja) subcutaneous LD 50 is 0.80 mg/kg, while the Cape cobra's (Naja nivea) subcutaneous LD 50 is 0.72 mg/kg. This makes the desert black snake a more venomous snake than both. [3]
