Learn More About The True Lizard (Lacertidae) Family
Some genera of this family, to which the lizards described belong, are also called collared lizards. They are differentiated from other lizards by a horizontal fold between the throat and the chest scales. At the back end of this fold the scales are noticeably enlarged. True lizards are among those that are able to discard their tails to deceive a pursuer. A typical submissive gesture is treading.
Differences between the sexes: The males always have distinctly prominent femoral pores and a thicker tail base than the female.
Reproduction: While the male of the Canary Islands lizards bites the neck of the female during copulation, the male of the Pityuses lizards bites the flank. Up to three egg clutches are buried every year in a damp place in the ground. The eggs must be transferred to the incubator because only there can constant humidity be guaranteed.
