Biology
Relatively small and stout pitvipers, reaching a maximum length of 50 cm. M. barbouri and M. browni are diurnal.
Although M. browni posses a prehensile tail it does not live high in the trees, but ascends into low vegetation. In M. melanurus a single scale above each eye forms a flattened horn.
The limited habitat range of Mixcoatl spp. makes this genus the most retricted of New World pitvipers. The three species live in altitudes above 1'600 m. M. barbouri in humid pine-oak and cloud forest, 2'300–2'600 m. M. browni in cloud forest, 1'800-3'300 m. M. melanurus in arid tropical scrub, deciduous forest and seasonally dry pine-oak forest, 1'600-2'400 m.
