Geckos are reptiles found all over the world except Antarctica. They belong to a different genus and a large variety of species. These colorful lizards are well adapted to different habitats from deserts, mountains, to cold boreal forests. Geckos differ in size and color. They are all nocturnal lizards mostly thriving in warmer regions. These creatures are unique among all lizards due to their vocalization. All species of geckos have different color adaptations to camouflage in their particular habitats and unique feet to climb vertical surfaces.

Commonly geckos eat small insects like cockroaches, beetles, butterflies, crickets, and millipedes. Some of the larger geckos like the Caledonian gecko also eat small lizards, mice, eggs, and tiny birds. The leopard gecko and crested gecko are the most loved reptile pets and feed on insects and fruits. In many countries, several species of geckos are sold in pet stores. Geckos are ancient animals. They have existed for around 300 million years. The common gecko is believed to have its origin in North Africa.

They are adapted to the warm and dry climate of the sandy semi-desert terrain of Iran, Pakistan, India, and Afghanistan.

The arboreal, red-spotted tokay gecko species native to Asia and some Pacific islands are known for their strong bite and unique look.

The mating ritual of geckos involves attracting a female by vibrating their tails and making unique sounds particular to mating. While most gecko species participate in sexual reproduction, a few species like the mourning gecko reproduce through parthenogenesis. More than 40 species found in New Zealand give birth to baby geckos.

Most geckos lay eggs. Female geckos store their eggs in leaves and twigs. Gestation periods range from around 20 days for a leopard gecko to about three to four years for a harlequin gecko. A clutch may contain one or two eggs. Eggs are usually laid on the ground hidden under rocks, dry leaves, and tree barks. Eggs typically take 35-90 days to hatch depending on the species.

Gecko Fun Facts

What do geckos look like?

Most geckos are small reptiles. These nocturnal reptiles look different from each other depending on their habitat, environment. Some geckos like the leopard geckos can change their color when they are young. Most geckos lack eyelids and have a transparent eyelid that they clean with their tongue. The missing eyelids are also a difference that makes them unique lizards. Eighteen species of geckos are known to have eyelids. Geckos lick their eyelids to clean them, keep them moist and cool. Because geckos do not have eyelids they sleep without shutting their eyes. As an alternative to save their eyes from the strong light, they hide in dark places during the day and save their eyes by contracting them.

Most of these reptiles have a stout body, four well-developed limbs with padded toes, a large head, and well-developed limbs. At the end of each limb are digits or toes that work like adhesive pads when climbing vertical surfaces. All geckos have fairly long tails. As a defense mechanism, some geckos like the day geckos and the popular pet leopard geckos shed their tails. Geckos shedding their tail, or the ‘tail-drop’ phenomenon happens naturally. For most geckos, it grows back. As geckos are spread in various habitats ranging from forests to deserts, their colors differ accordingly. They are quite smart to camouflage themselves, this adaptation feature helps the animals to protect themselves from their predators. Most of the gecko species are from 0.6-23.6 in (1.5-60 cm) long. They have adapted to habitats ranging from deserts to jungles and have body colors to suit their habitat.

Geckos have about a hundred teeth. Their teeth do not wear off as geckos replace their teeth in three to four months. The body of a gecko is covered with skin featuring millions of small hair-like spines. These are soft spines that trap water droplets. This mechanism saves the gecko’s skin from getting contaminated by dust. A gecko’s toes are covered by microscopic hair called setae. These hairs have the unique function of helping the gecko to climb vertical and plain surfaces.

Geckos are of different sizes and colors depending on their species

How cute are they?

Geckos are harmless animals. Some people find them extremely cute and keep them as pets.

How do they communicate?

Geckos can produce different sounds to communicate with their fellow animals. They are known to click, chirp, and even bark. This is a major difference between a lizard that cannot vocalize and a gecko that can. Geckos may make sounds when they are threatened, to frighten their competitors away from their territory, to attract females. Some gecko species also make sounds to avoid fighting.

Geckos are not very social. These reptiles are solitary animals with a more sophisticated vocal system than all other lizards. These lizards have a true vocal cord. Species like the New Caledonian gecko can even growl and that has earned it the name of ‘the devil in the trees’ in its native island.

A leaf-tailed gecko native to Madagascar screams like a child when in distress. Their tails are also a means to communicate with their fellow creatures. A slow and gentle wiggling movement may be a sign of indication that they sense another gecko in their surroundings. A fast shaking of their tails can mean aggression or a defensive move to distract or scare a predator.

Shaking the head is a common behavior of many species of geckos while the animals pass their food from their throat to their stomach. Most gecko species are nocturnal meaning they are most active at night looking for food. They climb with their padded feet, run, and even stomp across shallow water surfaces. The flat-tailed house gecko can move at the speed of 2 mph (3.2 kph).

How big is a gecko?

The largest gecko weighs 0.2 lb (90.7 g) and the largest monitor lizard weighs around 200 lb (90.7 kg). The heaviest gecko is 0.001 times the weight of a monitor lizard.

How fast can a gecko move?

A common gecko can run at the speed of 30 mph (48.3 kph).

How much does a gecko weigh?

A mature male gecko weighs around 0.1-0.2 lb (45.4-90.7 g) and a female gecko around 0.1 lb (45.4 g). The weight differs according to the species of gecko.

What are the male and female names of the species?

What do they eat?

Small insects are the favorite food of geckos. Grasshoppers, flies, spiders, crickets, and small rodents are included in the gecko diet. Pet gecko species also eat store-bought mealworms, fruits like papaya and apricot, and nectar. Store-bought gecko food often contains a mix of crickets and worms. Different gecko species have different favorites when it comes to food. The leaf-tailed gecko’s favorite is land snails and the New Caledonian gecko eats small insects, small birds, and also some rodents.

Are they poisonous?

The most important thing to know among other common house gecko facts is that these animals are harmless and non-venomous. The common house gecko or wall gecko is a Southeast Asian small lizard. They are commonly seen in gardens, porches, near lights at night, foraging on insects. Pet geckos in captivity may nip their human handlers if they feel threatened or being handled carelessly.

The most-kept pet gecko species are crested geckos, gargoyle geckos, leopard geckos, ground-dwelling African fat-tailed geckos, and Leachie or New Caledonian giant gecko. Pet stores provide gecko food, gecko toys, and every gecko essential. Long and shallow terrariums make good homes for geckos. Pet stores are ideal places to shop for gecko terrarium accessories like faux plants and rocks.

The world’s smallest gecko and reptile species, the Sphaerodactylus parthenopion is only 1.5 in (3.8 cm) in length.

A gecko’s feet can stick to all surfaces barring Teflon. The setae or tiny hair that help the gecko’s feet to stick to surfaces, are not straight but branch out at slanting angles.
