Gallotia
The genus Gallotia are the lacertids (wall lizards) of the Canary Islands. This genus consists of a group that has been evolving there ever since the first islands emerged from the sea over 20 million years ago. The endemic species and subspecies of this group have a number of characteristics that make them quite special within their family ( Lacertidae); their only close relatives are the sandrunner lizards ( Psammodromus) of the western Mediterranean region. Gallotia are characteristic for eating significant quantities of plants, and for several lineages having evolved insular gigantism.
