The Javan spitting cobra (Naja sputatrix), also called Indonesian cobra or Komodo spitting cobra, is a species of cobra in the family Elapidae, found in the Lesser Sunda Islands of Indonesia, including Java, Bali, Lombok, Sumbawa, Flores, Komodo, and others.
Like most other spitting cobras, its venom is primarily a postsynaptic neurotoxin and cytotoxin (necrotizing or tissue-death). [4] Like all cobras, this species shows variation in venom toxicity based on different factors (diet, locality, etc.). In a study of specimens from Thailand, the IV LD 50 was 0.28 μg/g (0.18-0.42 μg/g). [14]
Naja ashei Broadley and Wüster, 2007, Ashe's spitting cobra, is a newly described species found in Africa and also a highly aggressive snake; it can spit a large amount of venom. [ 41 ] [ 42 ] Naja nigricincta Bogert, 1940, was long regarded as a subspecies of N. nigricollis , but was recently found to be a full species (with N. n. woodi as a ...
A "spitting" cobra is any of several species of cobra that can intentionally, defensively shoot their venom directly from their fangs. This substance has two functions, with the first being as venom that can be absorbed via the victim’s eyes, mouth, or nose (or any mucous membrane or existing wound), and secondly as a toxungen , which can be ...
Red spitting cobra (Naja pallida), juvenile. Spitting cobras are another group of cobras that belong to the genus Naja. Spitting cobras can be found in both Africa and Asia. These cobras have the ability to eject venom from their fangs when defending themselves against predators. The sprayed venom is harmless to intact skin.
The population currently included in Naja sumatrana have a confusing history. The species was first defined as currently understood in 1989. [9] Previously, the populations of this species were assigned to several different subspecies of Naja naja (Indian cobra), in particular N. n. sumatrana (Sumatra), N.n. sputatrix (Peninsular Malaysia) and N.n. miolepis (Borneo, Palawan).

The monocled cobra has an O-shaped, or monocellate hood pattern, unlike that of the Indian cobra, which has the "spectacle" pattern (two circular ocelli connected by a curved line) on the rear of its hood. The elongated nuchal ribs enable a cobra to expand the anterior of the neck into a “hood”. Coloration in the young is more constant.
Instead of this, they block the nerve transmission in the body. α-Cobratoxin is a post-synaptic neurotoxin, which reversibly blocks the nicotinic acetylcholine receptors. A bite of the Thailand Cobra therefore leads to muscle paralysis. Because of that paralysis, respiratory problems may develop, which can lead to death.
