difference between spectacled cobra and monocled cobra

Incubation periods range from 55 to 73 days. The elongated nuchal ribs enable a cobra to expand the anterior of the neck into a “hood”. The proteomics finding revealed that the neurotoxin profiles of these Naja kaouthia were substantially different, reflecting the distinct difference in their lethal potency and response to antivenom neutralization. [1], Monocled cobras are terrestrial and most active at dusk. They prefer habitats associated with water, such as paddy fields, swamps, and mangroves, but can also be found in grasslands, shrublands, and forests.

However, when threatened they will raise the anterior portions of their bodies, spread their hood, usually hiss loudly, and strike in an attempt to bite and defend themselves.

Subcaudals in males range from 48 to 61, in females from 46 to 59. This species has been assessed as Least Concern by IUCN owing to its large distribution, tolerance of a broad range of habitats including anthropogenically altered environments, and its reported abundance. [5], 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.

It has a pair of fixed anterior (front) fangs. It has a black spot on the lower surface of the hood on either side, and one or two black cross-bars on the belly behind it. In a preliminary study, extract of Mimosa pudica plant has been shown to possibly have neutralizing effects on the toxins present in this venom.

But remember, again; the map may not be accurate or complete.

[16] The venom of this species also contains myotoxins and cardiotoxins. The biggest difference between the two is in the amount of brake horsepower that they are able to put out. Drowsiness, neurological and neuromuscular symptoms will usually manifest earliest; hypotension, flushing of the face, warm skin, and pain around bite site typically manifest within one to four hours following the bite; paralysis, ventilatory failure or death could ensue rapidly, possibly as early as 60 minutes in very severe cases of envenomation. The rest of the belly is usually the same color as the back, but paler. Little Egret, Intermediate Egret, Great Egret: what’s the difference? In case of intravenous injection the tested in mice is 0.373 mg/kg, and 0.225 mg/kg in case of intraperitoneal injection.
