Gigitan

Bisa keluar melalui taring atau giginya apabila ia menggigit.

Apa kesan bisanya?

Its venom is largely hemotoxic, meaning it damages blood and the tissue around the bite. Because the snake is small, it injects only small amounts of venom, so its bite is not as life-threatening as that of larger rattlesnakes. A bite can still cause pain and discomfort.1

Berapa bahaya ia kepada manusia?

berguna untuk diketahui

Fakta

It is the official state reptile of Arizona.1

The snake's ridge is made by upturned scales on the tip of its nose, which makes it easy to recognise.1

Although it is a rattlesnake, it gives birth to live young. The babies develop inside eggs that stay within the mother until they are born.1

Pemecah mitos

Mitos: Every rattlesnake bite is equally deadly.

Hakikat: This species has very low venom yields, so its bite is not as life-threatening as those of larger rattlesnakes, and no deaths have been documented.1
