Phylogeny within the genus Phrynocephalus is not well understood yet. There is a lack of data and controversy between opinions regarding both phylogenetic relationships and species vs. subspecies status of the different forms Phrynocephalus helioscopus and Phrynocephalus persicus, also called the “helioscopus-persicus complex”. The most recent works^[which?] suggest evidence supporting both. In 2008, Melnikov et al. also proposed a distinction ofP. horvathi at the species level.^[1][6]

This lizard’s life span is only about 2.5–3 years, and juveniles become adults at an age less that one year old. Persian Toad Headed Agamae feed on a variety of available arthropods ranging from ants, small spiders to beetles and orthopterans. Even venomous arthropods as spiders, bees and wasps can be ingested by this lizard.
