*''Gallotia galloti palmae'' - La Palma lizard (La Palma)
The large differences in colour pattern in adult males seems to have been the basis for the recognition of the Northern and Southern "subspecies". The northern form is found at low-mid altitudes on the north-facing slopes, while the southern form is found above the pine forest on the north facing slopes and the southern slopes of Tenerife. A recent genomics study has identified nuclear DNA differences between these regions, although they only seem to be found in small number of loci

The striking color of adult males and their curious nature endear them to many tourists. At popular sights, notably Mount Teide, the lizards have become rather tame and an attraction of sorts themselves. It is quite popular to bring some ripe bananas along for the lizards, which are a most favorite food of this species and will provide travellers with good photo opportunities as the animals scurry over the rocks and even onto visitor's hands to catch a bite.
