Have bred over 40 species of lizards mostly from California, Arizona and Mexico and am a horned lizard semi-expert, and have bred many species of horned lizards, was a contributor to www. phrynosoma.com have worked with many exotic lizards including Angel Island Chuckwallas back in the day, mostly breed desert species, have successfully bred Fringe-toed Sand lizards many times, have bred many collared lizard species over the years, and are one of my favorite lizards. Currently working with C. reticulatus in Texas under permit (SPR 1005-1509). Also will be working with some lizards from the Big Bend area next year... My expertise is working with lizards that have not been bred in captivity, developing captive husbandry, and studying lizards in their natural habitats and photo documenting.
