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.
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.
