Nyoka hawa ni warefu kiasi, sm 150 kwa kipeo lakini kwa wastani majike ni sm 60-100 na madume sm 40-70. Wana mkia mrefu kiasi, kichwa kwa umbo wa pembetatu na mboni za wima. Rangi yao ni kahawia, kahawianyekundu, kijivu au nyeusi. Kuna milia miwili myeupe pande mbili za kichwa na milia hii inaweza kuendelea mpaka mkia.

Chata hupumzika mchana katika vishimo au chini ya miamba, magogo au takataka. Huwinda usiku na hukamata panya hasa lakini ndege, mijusi na vyura pia. Waama, nyoka hawa ni muhimu sana kwa sababu wanasaidia watu kwa kuwaua wagugunaji wengi.

Nyoka hawa hawana sumu lakini spishi kadhaa hung'ata na kusababisha vidonda. Kwa kawaida huwa wanyama-vipenzi katika muda mfupi.
