Nyoka hawa sio warefu sana, kwa wastani sm 50-80 lakini kadhaa wanaweza kufika m 1.15. Rangi yao ni nyeusi, kijivu, kahawia au nyekundu na wana madoa au mabaka mara nyingi.

Chamayai hula mayai tu. Kwa hivyo wanatokea katika maeneo yenye miti mingi ambayo juu yao ndege wajenga matago yao. Wana vetebra kadhaa katika shingo zinazichomoza ndani ya koromeo. Baadha ya kumeza yai zima nyoka abinya koo lake na kutoboa yai kwa vetebra zile. Kisha akama uowevu wa yai na kutapika vipande vya ganda.
