Agama aculeata aculeata and Agama planiceps planiceps females were reproductively active during summer, which is the rainy season in Namibia. Both species were iteroparous; clutch size and relative clutch mass in the smaller A. a. aculeata were significantly larger than in A. p. planiceps. Egg and newborn hatchling size of A. a. planiceps on the other hand were significantly greater than in A. a. aculeata. It is suggested that these differences may have evolved as a result of different strategies which the two species possibly employ to cope with predation pressure, namely, evasion through crypsis in A. a. aculeata and through speed of escape in A. p. planiceps.
