The species inhabits areas very similar to its sister species, Chalarodon madagascariensis: semi-arid to arid regions with sandy soil that are mostly open.
Calarodon steinkampi is a cryptic species. It is easiest distinguished from C. madagascariensis by its unkeeled gular and ventral scales, which are keeled in the latter species. Other subtle differences include the mental scale being in contact with four postmentals (rather than 5–8), slightly shorter limbs, and fewer spines in its dorsal crest.
The Madagascar sand lizards are insectivores. In addition to insects, sometimes plants are ingested, particularly in the form of leaves and roots.
