Heloderma h.horridum described by Wiegmann 1829. Also known as
Escorpio’n or Acaltetepo’n (Beck 2005). Is the most
common sub species of Heloderma horridum. Found on the Pacific
coast from southern Sinaloa all the way down to Oaxaca Mexico.from
near sea level to 1500 meters (Beck 2005).
With its larger range H.h.horridum has the most variable color
patterns of all four sub species. Their colors range from large
amounts of yellow to almost all black. They seem to intergrade
in eastern Oaxaca with H.h.alverezi (Beck 2005). The largest Beaded
Lizard in captivity owned by Robert W. Applegate is in excess
of 40". Although sub species is not a differentiating factor
when it comes to size. I am working with a group of reduced yellow
"Super Black" H.h.horridum. I have been selectively
breeding the color out for the past few years. Pictured are some
of my animals.
