The animal on the cover of Programming Flex 2 is a krait snake. The krait (Bungarus caeruleus) is one of the deadliest venomous snakes in the world. Their native habitat is limited to Asia, and they are nocturnal. The snake’s bands are white or yellow on a blue/black body, the head is narrow, and a krait can grow to nearly three feet in length.
Fairly common in the fields and jungles of India, Pakistan, and Sri Lanka, the krait is also known to seek shelter in human encampments. They are fond of hiding out in sleeping bags, footwear, and piles of clothing or rags. Their venom contains a neurotoxin that causes respiratory failure; victims often feel little pain from the bite itself, but the death rate of victims is 85 percent without administration of anti-venom, and nearly 50 percent even when medication is available.
The 2006 film Snakes on a Plane features a snake smuggler named “Kraitler,” and the krait makes an appearance in several Sherlock Holmes stories.
