Crotalus ruber lucasensis, the San Lucan diamond rattlesnake,[3] 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

The generic name Crotalus is derived from the Greek word κρόταλον krótalοn, which means "rattle" or "castanet", and refers to the rattle on the end of the tail, which makes this group (genera Crotalus and Sistrurus) so distinctive. As of July 2023, 44 to 53 species are recognized as valid.

The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
