Adults of X. merremii are usually 1 m (39 in) or less in total length (including tail).[4] Its color pattern is very variable.[2] Some "red phase" specimens are a uniform reddish tan.[4] Other specimens are pale brown dorsally, with broad dark-brown crossbands, which are edged with black, and are narrower or interrupted in the middle.[5] The latter color pattern resembles that of the venomous snakeBothrops alternatus.[4]
Dietedit
X. merremiipreys on insects, frogs, toads, lizards, and sometimes snakes. Like other rear-fanged toad-eaters of the generaHeterodon and Lystrophis, X. merremii uses its enlarged posterior maxillary teeth to puncture and deflate toads which have defensively puffed themselves up, thereby making them easier to swallow.[4]
Defensive behavioredit
When threatened, X. merremii raises the anterior part of its body, inflating and spreading its neck, similar to a cobra.[4]
