The false water cobra is a large snake that lives in South America. It is named after true cobras because it flattens its neck to look bigger when threatened, but it is not a true cobra. It is mildly venomous, and its bites rarely cause serious harm to people.1

Tge fa ses tissi?

This snake has enlarged rear teeth that are not grooved, and they are linked to a gland that produces oral secretions with proteolytic activity, meaning they break down proteins. In the few serious cases, symptoms included severe swelling, bruising, numbness, itching and dizziness. Most bites cause only mild pain and minor swelling.1

Fatgs

Captive-bred individuals can become quite tame and trusting, and many show a high level of intelligence.1

Temperaments vary a lot: some individuals are docile, while others are defensive or even aggressive.1

Males are much smaller than females, a difference called sexual dimorphism.1

It is mainly active during the day, which gives it good daytime vision thanks to its large eyes.1

Destructur da mits

Mit: It is a true cobra.

Vardad: It is not a true cobra. It hoods in a similar way, but stays horizontal instead of rearing up.1
