Their first defensive strategy to avoid predators is to remain still, using their body color to blend in with their surroundings. If this strategy fails, they will attempt to hide in undergrowth or cover themselves in sand. If this fails, they will try other defensive tactics such as hissing, biting,

but they do eat spiders, beetles, termites, and other insects. Harvester ants require dry conditions and therefore struggle in cultivated urban ecosystems with irrigated lawns, which in turn impacts horned lizard populations.

The San Diego Horned Lizard or the
Blainville's Horned Lizard (Phrynosoma blainvillii) is a flat bodied lizard with long spiky horns located on the top and side of its head and has smaller spikes throughout its body and tail.

The difference between males and females is that the female lizards are bigger than the males. The males also have bigger horns on the base of their tails and have noticeable pores on the interior of their hind legs.
462:
The lizard’s population was also impacted by the curio trade from 1890-1910, where it was estimated that 115,000 horned lizards in

The San Diego horned lizard is no longer present in many sections of
