Description
 
Size
Adults grow up to 6 inches long (15 cm) including the tail.
Moorish Geckos are usually around 3.2 inches long (8 cm) from snout to vent.

Appearance
A robust-bodied lizard with a flat head, prominent tubercles on the upper surfaces, large bulging eyes with vertical pupils and no eyelids, and elongated toe pads.
The tail is easily detached, but it will regenerate. Regenerated tails do not grow tubercles.
Color and Pattern
Color is brownish, grey or sandy with dark and light markings.
Color changes from dark during daytime to light phase at night.
The underside is white to yellow.
Young
Young geckos have dark bands.

Life History and Behavior

Activity
Nocturnal, but also known to bask in the sun during cooler parts of the year.
A good climber.
Territoriality
Males defending territories make squeaking calls.
Defense
The tail is easily detached and when detached will wriggle for a few minutes which may distract a potential predator from the gecko long enough for it to escape.
Diet and Feeding
Eats small invertebrates and possibly small vertebrates.
Often seen foraging for food under artificial light sources.
Breeding
In its native habitat, 2 - 3 clutches of 1 or 2 eggs are laid around April and June.
Moorish Wall Geckos take several years to reach sexual maturity.

Habitat
Found in its native habitat on stone walls, boulders, and piles of wood in warm, dry, lowland coastal areas.
Alien populations are typically found on inside and outside walls and cinderblock fences.

Geographical Range
The species is native to the coastal Mediterranean area of Europe and Africa.
It has been established in Florida, California, Argentina, and Uruguay.

Geckos in California could have originated as escaped pets or they could have been transported from wild populations, probably from Florida originally, and then from other California populations.


The first published report of this species being established in California was in 1998:
" This lizard has been introduced and established in San Diego County, California."
(Mahrdt, 1998, Herpetol. Rev. 29: 52)



These are locations where this species has been found in California and appears to be established, based on museum records, published information, and personal communications. It is most likely present at other locations, also.
