The pygmy rattlesnake is a small, venomous snake that lives in the southeastern United States. It is the smallest rattlesnake found on the North American continent. Its venom is strongly tissue-damaging, but the snake makes so little that a bite is unlikely to be fatal to an adult.1

Gigitan

Bisanya keluar lewat taring atau gigi saat menggigit.

Apa efek bisanya?

Its venom is cytotoxic, which means it damages cells, and it is strongly haemorrhagic, which means it causes bleeding. The venom is tissue-toxic but contains no neurotoxins, which attack the nerves. The snake produces only a small amount of venom and contains substantial amounts of serotonin and related compounds.1
