Heloderma h.exasperatum described by Bogart & Del Campo 1956
also called the Rio Fuerte Beaded Lizard. Is the Northern most
race of Heloderma horridum inhabiting the drainage basins of the
Rio Fuerte & the Rio Mayo areas of southern Sonora & Northern
Sinaloa Mexico(Beck 2005).
H.h.exasperatum is sub tropical and the most colorful sub species
of Beaded lizard where variations of yellow often exceed the black
or brown. The Rio Fuerte Beaded Lizard is most active and comfortable
at 78 to 88 F. I am working with nine unrelated bloodlines of
pure H.h.exasperatum of which all have been selected by me for
the highest amount of color and reduced black. Pictured below
are some of my breeders, juveniles and hatchlings.
