Crotalus ruber lucasensis is a venomous pitviper subspecies[4] found in Mexico in the Cape region of lower Baja California.


Similarly to C. r. ruber, adult specimens commonly exceed 100 centimetres (39 in) in length. Both of these subspecies can be identified by having prenasals that are usually in contact with the first pair of supralabials, an absence of interchinshields, and by having tail rings that are either complete, or broken at the midline, but usually not laterally.[5]:579 However, this subspecies in particular exhibits a tendency for rattle loss.[5]:491

Geographic range[edit]
