Tokay gecko

The tokay gecko is a large lizard.

It lives in forests in Asia. It stays in trees and on rocks. It is most active at night.

This gecko has soft skin. It is blue-gray with red spots. It can even change its color. This helps it hide in its home.

These lizards are very strong climbers. They have pads on their feet. These pads help them walk on walls.

They like to eat small things. They hunt for bugs like crickets. They also eat small animals.

Male geckos make a loud sound. It sounds like "to-kay." This is how the lizard got its name.

The tokay gecko is a large lizard.

It lives in Asia and some Pacific Islands. These geckos are nocturnal. This means they are active at night. They live in rainforests on trees and cliffs. Sometimes they live near people on walls and ceilings.

This gecko has soft skin. It is blue-gray with red or orange spots. The skin can change color to help it hide. Males are larger and brighter than females. This is called sexual dimorphism. It means males and females look different.

Tokay geckos are strong climbers. They have foot pads to help them. These pads hold their whole weight on walls. They have large heads and strong jaws. They can give a very strong bite.

They eat insects like crickets and beetles. They also eat small animals. Males make a loud croak. The sound sounds like "to-kay." This is how they got their name. They can live for 15 to 20 years.

The tokay gecko is a large and interesting lizard. It is a nocturnal animal, which means it is active at night. These geckos live in rainforests on trees and cliffs. They are also found in many parts of Asia and some Pacific Islands. You might even see them near people. They often roam on walls and ceilings in rural areas to find food.

This gecko has a very special way of moving. It is a strong climber with special foot pads. These pads can support its whole weight on a vertical surface for a long time. The gecko has a cylindrical body that is a bit flattened. It also has a semiprehensile tail, which helps it grip things. Its skin is soft and usually blue-gray with red or orange spots. The gecko can even change its skin color to blend into its home.

People have known about these lizards for a long time. A scientist named Carl Linnaeus described the species in 1758. The name "tokay" comes from the loud sound the males make. It is an onomatopoeia, which is a word that sounds like a noise. The name sounds like "tuck-too" or "to-kay." In Javanese, the word is "ge'kok." This is where the names for the whole family of geckos come from.

There are many specific facts about how they live. The tokay gecko is the third-largest gecko in the world. It can grow as long as a ruler. There are two subspecies of this gecko. One lives from India to Indonesia. The other is found only in Bangladesh. In Cambodia, researchers saw up to four adults guarding one group of eleven eggs. These geckos can live for 15 to 20 years in captivity.

These lizards are part of our world in many ways. In Southeast Asia, people see them as symbols of good luck. Some even believe they come from dragons. However, they face hard jobs in the wild today. Many are taken from nature for the pet trade or for medicine. In the Philippines, hunting them can lead to big fines or jail. This is because they are becoming a threatened species there.

The tokay gecko (*Gekko gecko*) is a large, nocturnal lizard. It belongs to the genus *Gekko*, which contains the true geckos. These animals are arboreal, meaning they live primarily in trees. They are native to various parts of Asia and some Pacific Islands. This species is quite important to study because of its unique biology and its relationship with humans. They are known for being quite large and having very strong personalities.

To move through their environment, tokay geckos use specialized physical features. They possess foot pads that allow them to support their entire body weight on vertical surfaces. This ability helps them climb trees and cliffs for long periods. Their body is somewhat flattened and cylindrical in shape. They also have a semiprehensile tail, which means it can help them grip objects. Their eyes feature vertical pupils, which are helpful for seeing at night. The gecko can even change its skin color to blend into its surroundings.

There are two recognized subspecies of the tokay gecko. The first is *G. g. gecko*, which was described by Carl Linnaeus in 1758. This subspecies lives in tropical Asia, ranging from northeastern India to eastern Indonesia. The second subspecies is *G. g. azhari*, described by Mertens in 1955. This specific subspecies is found only in Bangladesh. These different groups help scientists understand how the species has spread across different regions over time.

Scientists and people have interacted with these geckos for centuries. The name "tokay" is an onomatopoeia, which is a word that mimics a sound. It represents the loud, croaking mating call made by the males. In Javanese, the word is "ge'kok," which is where the names for the family Gekkonidae come from. During the Vietnam War, U.S. soldiers gave them a different, colorful nickname. The frequency of their calls often changes based on the ambient temperature. This suggests that calling might help them regulate their energetic metabolism.

In terms of size, the tokay gecko is a massive member of its group. It is believed to be the third-largest species of gecko in the world. It follows the giant leaf-tail gecko and the New Caledonian giant gecko. An adult can reach a total length that is as long as a ruler. They are also sexually dimorphic, meaning males and females look different. Males are generally larger and have more brightly colored skin than females.

These lizards have very specific diets and social behaviors. They primarily eat insects and small vertebrates. In the wild, they hunt things like cockroaches, caterpillars, spiders, and beetles. In captivity, they might eat mealworms, crickets, or even pink mice. Their social lives can be quite interesting as well. In Cambodia, researchers observed communal nesting. This involved up to four adults guarding a single clutch of about eleven eggs. They can even tell their own offspring from other geckos by using their sense of smell.

However, the tokay gecko faces many modern challenges. They are culturally significant in East Asia, where they are symbols of fertility and good luck. Unfortunately, they are also poached for the medicinal trade. In some places, they are used in traditional Chinese medicine, known as *Ge Jie*. This trade has led to them becoming a threatened species in the Philippines. In that country, illegal hunting can result in heavy fines or even 12 years in jail. The species is protected under Appendix II of the CITES treaty to help manage international trade.
