Kuasa bisa

Gigitan

Bisa keluar melalui taring atau giginya apabila ia menggigit.

Apa kesan bisanya?

Its venom is a weak hemotoxin, meaning it attacks blood and tissue. It can cause respiratory failure, which is when breathing fails. In humans, bites cause severe pain that can spread well beyond the bite and last up to 24 hours, along with swelling, weakness, sweating and a rapid drop in blood pressure.1

Berapa bahaya ia kepada manusia?

Human deaths from its bites are rare. Eight human bites were documented in the past century, and almost all happened when people prodded captive lizards with a finger or bare foot.1
