Common wall gecko description

KingdomAnimalia
PhylumChordata
ClassReptilia
OrderSquamata
FamilyPhyllodactylidae
GenusTarentola (1)

The common wall gecko (Tarentola mauritanica) is, as its name suggests, a very common gecko species (1). The largest gecko in Europe (3), it is a hardy, plump-looking lizard with a flattened head and body, and is perfectly adapted to a life of climbing (4). The common wall gecko has specialised microscopic suction pads on its toes, known as ‘setae’, which allow the gecko to climb flat surfaces including walls and ceilings (4) (5).

The common wall gecko looks spiky because it is covered in prominent bumps or tubercles. Generally, this species is a dull brownish, greyish or whitish colour, with a white or yellowish belly, and dark bands which are most conspicuous on its tail (4). However, the common wall gecko has the ability to change the colour on its back to better match its surroundings and make it less conspicuous to predators (2).

The eyes of the common wall gecko are usually greyish, and its pupils are vertical and slit-like. This species’ tail is roughly equal in length to its head and body. If the common wall gecko is attacked it can drop its tail, but when the tail grows back it lacks the dark bands and spiny appearance it had before (4).

There is not much difference between the appearance of the male and female common wall gecko, except that males are bigger and heavier and tend to have larger heads, although this difference can be difficult to detect when they are still young (3). Three subspecies of common wall gecko are sometimes recognised (6). However, the taxonomy of this species needs further investigation, as some populations may potentially represent separate species (1).

Common wall gecko biology

The common wall gecko is primarily nocturnal, but will bask during the day to regulate its body temperature (4). The common wall gecko preys upon arthropods, but its diet and hunting strategy change according to its habitat. In its natural habitat, this species eats mainly spiders, caterpillars and beetles, and it must actively forage as this prey is widely distributed. In contrast, in urban habitats, the common wall gecko sits and waits near lights where it typically catches flies and moths (9).

During the breeding season, the male common wall gecko is usually territorial and makes loud calls to attract females. The female common wall gecko makes calls during the brief mating (4). This species lays two or three clutches of one or two eggs at a time, sometimes communally, under stones or in cracks or hollow trees (1) (4). The eggs may take up to 14 weeks to hatch, and the common wall gecko hatchling is no longer than 2.5 centimetres in snout-vent length, or just 6 centimetres in length including the tail. In captivity, the common wall gecko may live for up to eight years (4).

Common wall gecko range

The common wall gecko is widespread across North Africa and the Mediterranean, ranging from the Iberian Peninsula, across southern France and coastal Italy to Greece, and from Egypt west to Morocco and northwest Western Sahara (1) (4) (6) (7). It also occurs on many Mediterranean islands, including Sardinia, Corsica, Sicily and Crete, and has been introduced to the Balearic Islands, Tenerife, Madeira and other islands (1) (4) (6).

As well as being widespread across its native range, the common wall gecko has also repeatedly been introduced across the Atlantic and has become established in parts of the United States, Argentina and Uruguay (1) (6).

Common wall gecko habitat

The common wall gecko is naturally found in warm, dry coastal areas, although its range also extends inland in some areas (4), and it has been recorded at elevations as high as 2,300 metres in Spain (1). It occurs in a variety of habitats, including rocky cliffs, stone walls and rocky outcrops, and is occasionally found on trees (1) (4). An adaptable species, the common wall gecko also thrives in urban habitats, where it is found on walls, ruins and houses (1) (4) (8).

Common wall gecko status

The common wall gecko is classified as Least Concern (LC) on the IUCN Red List (1).

Common wall gecko threats

The common wall gecko is an adaptable, successful species, particularly in urban habitats, and there are no major threats to its continued survival at present. However, this species is a popular pet, and exploitation for the pet trade can be an issue in localised populations. Habitat degradation has also been identified as a potential threat to this gecko in Egypt (1).

Common wall gecko conservation

Due to its widespread distribution and high population numbers, the common wall gecko is not currently considered to be at risk of extinction. Much of this species’ range coincides with protected areas, and the common wall gecko itself is protected by international legislation in some regions (1).

Suggested conservation measures for the common wall gecko include further studies into its taxonomy, as well as investigations into the potential impacts of the pet trade on this small reptile (1).

Glossary

Arthropods
A major grouping of animals that includes crustaceans, insects and arachnids. All arthropods have paired jointed limbs and a hard external skeleton (exoskeleton).
Nocturnal
Active at night.
Snout-vent length
A standard measurement of body length of reptiles. The measurement is from the tip of the nose (snout) to the anus (vent), and excludes the tail.
Subspecies
A population usually restricted to a geographical area that differs from other populations of the same species, but not to the extent of being classified as a separate species.
Taxonomy
The science of classifying organisms, grouping together animals which share common features and are thought to have a common ancestor.
Territorial
Describes an animal, a pair of animals or a colony that occupies and defends an area.
Tubercle
A small, rounded, wart-like bump on the skin or on a bone.
