are geckos carnivores
Hello. Welcome to solsarin. This post is about “are geckos carnivores“.
Geckos are small, mostly carnivorous lizards that have a wide distribution, found on every continent except Antarctica. Belonging to the infraorder Gekkota, geckos are found in warm climates throughout the world. They range from 1.6 to 60 centimetres (0.6 to 23.6 inches).

Geckos are unique among lizards for their vocalisations, which differ from species to species. Most geckos in the family Gekkonidae use chirping or clicking sounds in their social interactions. Tokay geckos (Gekko gecko) are known for their loud mating calls, and some other species are capable of making hissing noises when alarmed or threatened. They are the most species-rich group of lizards, with about 1,500 different species worldwide. The New Latin gekko and English ‘gecko’ stem from the Indonesian-Malay gēkoq, which is imitative of sounds that some species make.
All geckos, except species in the family Eublepharidae lack eyelids; instead, the outer surface of the eyeball has a transparent membrane, the cornea. They have a fixed lens within each iris that enlarges in darkness to let in more light. Since they cannot blink, species without eyelids generally lick their own corneas when they need to clear them of dust and dirt, in order to keep them clean and moist.
Unlike most lizards, geckos are usually nocturnal and have excellent night vision; their colour vision in low light is 350 times more sensitive than human eyes. The nocturnal geckos evolved from diurnal species, which had lost the rod cells from their eyes. The gecko eye, therefore, modified its cone cells that increased in size into different types, both single and double. Three different photo-pigments have been retained, and are sensitive to ultraviolet, blue, and green. They also use a multifocal optical system that allows them to generate a sharp image for at least two different depths.
While most gecko species are nocturnal, some species are diurnal and active during the day, which has evolved multiple times independently.
Many species are well known for their specialised toe pads, which enable them to grab and climb onto smooth and vertical surfaces, and even cross indoor ceilings with ease. Geckos are well known to people who live in warm regions of the world, where several species make their home inside human habitations. These, for example the house gecko, become part of the indoor menagerie and are often welcomed, as they feed on insect pests; including moths and mosquitoes. Like most lizards, geckos can lose their tails in defence, a process called autotomy; the predator may attack the wriggling tail, allowing the gecko to escape.
The largest species, the kawekaweau, is only known from a single, stuffed specimen found in the basement of a museum in Marseille, France. This gecko was 600 millimetres (24 inches) long, and it was likely endemic to New Zealand, where it lived in native forests. It was probably wiped out along with much of the native fauna of these islands in the late 19th century, when new invasive species such as rats and stoats were introduced to the country during European colonisation. The smallest gecko, the Jaragua sphaero, is a mere 16 millimetres (0.63 inches) long, and was discovered in 2001 on a small island off the coast of Hispaniola.
5 Incredible Gecko Facts!
Geckos are standouts among the reptile class in a number of respects:
- These reptiles can climb practically every vertical surface effortlessly thanks to the tensile suction created by hundreds of thousands of tiny hairs on their toes.
- Geckos are the only lizards with true vocal cords.
- These reptiles clean their eyes by licking them.
- When they lose their tails to predators, they can regenerate new tails.
- These reptiles replace their teeth by growing new ones every three to four months.
Gecko Scientific name
These animals belong to a taxonomic group that shares the designation “squamate reptiles.” “Squamate” is derived from the Latin word “squamatus,” which means scaly, although these reptiles themselves don’t have scales. They belong to the infraorder Gekkota, a name thought to derive from the Indonesian-Malay “gēkoq,” which is a transliteration of the sound this animal makes.
Though these reptiles are not particularly social animals, they have a sophisticated vocal communication system when compared with other lizards. They have true vocal cords. Geckos bark and chirp to define their territory, to attract mates, and to elude predators; they also hiss and emit high-pitch squeaks. The New Caledonian gecko has such a distinctive growl that native tribes of those islands dubbed it “the devil in the trees.” The leaf-tailed gecko of Madagascar emits a distress call that many liken to a child’s scream.
They also use their tails to communicate with other geckos. Slow, wiggling movements indicate awareness of another animal’s presence while more vigorous shakes are defensive maneuvers designed to distract or evade predators.
Another characteristic of their behavior is head shaking. This movement is associated with feeding, and it helps the animal pass food from its throat to its stomach.
Most species are nocturnal. The night is the time when they climb most actively. They kos are swift runners, too; flat-tailed house geckos have been clocked at three feet per second, and they can scamper over the surface of the water.
These reptiles live in a variety of warm habitats on every continent of the globe except Antarctica. The immense amount of morphological variation found in different species reflects the ways that they have evolved to fit into their specific habitats. The Northland tree species, for example, owes its bright green color to the New Zealand forests and scrublands it inhabits. The leopard gecko with its yellowish skin and black spots blends in well with the semi-desert terrain of its native Pakistan, India, and Afghanistan. Red-spotted tokay species are well concealed in the lowland or submontane rainforests of southeast Asia while black-spotted tokay species have adapted to the rockier regions of Vietnam and China.
Are geckos carnivores?
Most Geckos are carnivores. Carnivores are animals that only eat meat. They eat insects, like flies, mosquitos, and cockroaches. (A gecko would be good to have around the house as a pet!).
Can leopard geckos eat human food?
The fact of the matter is that leopard geckos cannot eat any human foods. They are insectivores, meaning they eat nothing but insects and drink nothing but water.
Are geckos omnivores?
For the most part lizards and geckos are insectivorous and omnivorous. Crickets, mealworms, fruit and vegetable matter and the occasional pinky mouse can find their way into a standard lizard diet.
What can I feed my leopard gecko that won’t eat?
Feed your gecko some of its favorite foods. Safe insects include crickets, mealworms (not for the main diet because of lack of nutrition and hard exoskeleton), waxworms (treats only, very addictive), silkworms and dubia roaches. Make sure the insects you offer aren’t too large as this can cause injury to your gecko.

What Do Geckos Eat?
If cows are herbivores (they eat plants) and cats are carnivores (they eat meat) and people are
omnivores (they eat both plants and meat) then what’s a gecko?
An insectivore. (Really!) Geckos eat mostly insects (which makes them a special kind of
carnivore.) Geckos love crickets and grasshoppers and earthworms and mealworms—insects and
worms! (There’s no such thing as a wormivore, sorry.)
Common house geckos are native to southeast Asia and the Indo-Australian Archipelago. Due to the recent introductions, they now occur in many other countries uncluding the United States, countries in South and Central America, Africa, South Asia, and the Middle East. These lizards prefer to live in urban environments, in close proximity to city bounds and villages. Without access to the urban landscape, they inhabit eucalypt woodland, rain forests, open fields, savannas, and deserts. They are often seen beneath rocks or rotting logs, on trees, around bushes but most commonly they are found on buildings.
Their Food List
Leopard geckos are insectivorous. This means they eat insects and need to be fed a 100% live prey diet. Some of the best foods for leopard geckos include:
- House crickets
- Dubia cockroaches
Foods That Leopard Geckos Should Not Eat
Along with fruits and vegetables, there are several kinds of live prey and human foods that can cause health problems. Do not feed your gecko anything from this list:
- Chicken, beef, pork or processed meat
- Dog, cat or ferret food
- Fireflies (a single firefly can kill a leopard gecko in minutes)
How Long Can A Leopard Gecko Go Without Food?
Hatchlings and juveniles grow very fast. Their weight gain should slow down as they reach a year old. However, if your yearling does not eat for more than four days, you should take it to a vet. Adults can go for over a week without eating when shedding. You should take adults to a vet if they refuse to eat for more than ten days.
