Kuasa bisa

Gigitan

Bisa keluar melalui taring atau giginya apabila ia menggigit.

Apa kesan bisanya?

Its venom is a powerful hemotoxin, which damages blood and tissue. It can cause swelling, necrosis (death of body tissue) and severe pain. Its yield is low, so each bite delivers less venom than a larger rattlesnake's bite would.1

Berapa bahaya ia kepada manusia?

Bahaya kepada manusia: SeriusGigitannya perlu dirawat doktor. Kematian sangat jarang berlaku.

Its bite is less severe than that of larger rattlesnakes because it delivers less venom. Even so, the bite can be fatal if it is not treated.1

Berita baik: doktor ada ubat (antibisa) atau rawatan untuk ini.1

Apa yang ia buat apabila takut?

Its rattle is not a reliable warning, because its high pitch is easy to miss.1

Jika ia menggigit

Treatment should be sought immediately for any venomous snake bite. The antivenin CroFab is not specific to this snake, but it can be used to treat severe envenomation from massasaugas.1
Pastikan orang itu tidak bergerak dan tenang, letakkan anggota yang digigit pada paras jantung, tanggalkan cincin dan barang yang ketat, dan pergi ke hospital dengan segera.
