1. Chameleons change colors to communicate, not camouflage.

Contrary to popular belief, these colorful lizards change colors not to blend in but to message fellow chameleons and regulate their internal body temperature. As social animals, they artfully communicate their mood, intent, or health through these color displays. 

For example, male chameleons might display a vivid color palette to entice a mate or assert dominance during territorial disputes5. In contrast, a threatened chameleon could adopt darker tones to appear more intimidating to predators. 

Additionally, this adaptable skill plays a crucial role in managing a chameleon's body heat. They can darken their pigmentation to absorb sunlight or lighten it to reflect heat and cool down.

The chameleons' skin changes color using several chromatophores: xanthophores for yellow pigments, erythrophores for red pigments, and melanophores for black and brown pigments. Alongside these pigment cells, chameleons also possess iridophores and leucophores, which reflect and scatter light to create blue and white hues. 

2. There are over 200 different chameleon species in the world.

Over 200 known species of chameleons live around the world, such as the Parson's Chameleon and the Pygmy Leaf Chameleon. These reptiles are members of the Chamaeleonidae family and have evolved to thrive in diverse environments. 

From the vibrantly patterned Panther Chameleon to the unassuming Leaf Chameleon, these creatures showcase nature's adaptability and artistic flair. For instance, a desert dweller, the Namaqua chameleon, changes its color quickly to regulate body temperature. In contrast, arboreal species like the Veiled Chameleon navigate treetops effortlessly with their prehensile tails.

The word chameleon derives from the Greek words 'khamai', meaning 'on the ground,' and 'leon,' meaning 'lion,' thus figuratively translating to 'lion of the ground.'

3. Chameleons have excellent vision.

These fascinating reptiles can move their eyes independently, giving them an impressive 360-degree field of vision. As a result, they can observe their surroundings in every direction without moving their head. 

Moreover, a chameleon's eyes work like high-tech periscopes, rotating on their axes to gather details from all angles. Thanks to this, the lizard chameleons' eyesight enables them to look at two things or areas simultaneously. For example, a chameleon can observe a scrumptious insect with one eye while the other watches for threats. 

4. Chameleons’ prehensile tails and feet help them move around trees.

Like the Veiled Chameleon, chameleons have evolved adaptations on their tails and feet, equipping them for life among the trees. A chameleon's prehensile tail can curl around branches and offer additional support and stability. 

Moreover, chameleons' tails act like a fifth limb, easily maneuvering the treetops (technically referred to as arboreal locomotion). Some chameleons trust their tail strength so much that they even sleep while dangling from it3.

On the other hand, their zygodactyl feet are a unique arrangement of two toes pointing forward and two pointing backward. 

This design grants them a firm grip on branches, allowing them to navigate their environment confidently. Chameleons also have specialized pads called tarsal spurs to enhance their grip. Their sharp claws are perfect for digging into tree bark when they need extra stability. 

5. Chameleons move slowly.

Chameleons have developed a slow and deliberate movement style. Their cautious way of traversing their environment allows them to expertly escape the attention of predators, increasing their chances of survival. 

Conserving energy is another advantage of their unhurried movements. However, a chameleon can accelerate when it needs to. When threatened or hungry, they can suddenly accelerate at incredible speeds. They can launch forward at up to 21 body lengths per second.

Their body is equipped with specialized muscles and tendons that act like springs. Despite this impressive speed, chameleons prefer stealth and patience in navigating their habitat.

6. Chameleons' long and sticky tongues catch prey fast.

Did you know that chameleons' main asset is not their ability to change their skin color but their long and sticky tongue? These tongues are perfectly designed to snatch prey from a considerable distance2

Chameleons' tongues can stretch up to twice their body length, enabling them to grab insects without moving. This impressive reach helps them ambush prey (like stick insects, stick bugs, and grasshoppers) while staying undetected. More importantly, a chameleon's tongue can also move impressively fast. Using cars as an analogy, their tongues accelerate from 0 to 60 mph in a mere 1/100th of a second. This ability is among the quickest and strongest in the natural world.

7. Chameleons don’t have ears.

Another surprising chameleon fact is that chameleons have no ears. Instead, they perceive sounds through vibrations in the environment. They don't have external ear structures and eardrums but have developed an alternative method for processing auditory information. 

At the heart of their hearing system lies a small internal bone called the columella, directly connected to their jawbone. This unique structure enables chameleons to perceive vibrations and low-frequency sounds in the 200-600 hertz range, a sharp contrast to the human hearing range of 20-20,000 hertz.

How does this extraordinary ability to feel sounds affect a chameleon's survival? Although their hearing range is limited, it is finely tuned to their natural environment. This sensory adaptation also affects their ability to communicate with other chameleons, employing low-frequency sounds to relay information. 

Moreover, their sensitivity to vibrations lets them notice subtle changes in atmospheric conditions, such as the approach of a storm.

8. Chameleon bones glow in the dark.

In 2018, an international team of researchers from Germany and Madagascar discovered these lizards have bio-fluorescent bones. They examined 160 specimens from 31 species of chameleons. 

When exposed to ultraviolet (UV) light, these creatures' bones glowed blue. This luminescent effect was most visible near their eyes and mouths. Moreover, they saw unique patterns through their thin skin, otherwise hidden under normal light conditions6.

Notably, their bones can glow in the dark thanks to a protein called osteoclast-activating factor (OAF) found within a chameleon's skin and bones. OAF causes the bones to emit a mesmerizing blue glow under UV light. 

The exact purpose of these glowing patterns remains a mystery, but experts believe they might be crucial for communication or camouflage. For instance, the fluorescent markings could help chameleons identify each other in low-light environments.

9. Chameleons have zygodactylous toes.

Chameleons' zygodactylous toes enable chameleons to maintain a stable and secure grip while navigating tree branches and foliage in their arboreal habitat. How exactly do they work?

Most lizards have five toes. However, each chameleon foot has a set of fused toes. Its front feet have two fused toes on the outside and three on the inside. Meanwhile, the reverse is true for its back feet. Their foot structure allows chameleons to clasp branches with impressive agility and precision4.

10. The Jackson’s Chameleon gives birth to live young.

While most chameleons lay eggs, a few species, such as Jackson's Chameleons, give birth to live young. The female Jackson's Chameleon stands apart from most chameleons due to ovoviviparity. 

Female Jackson Chameleons carry the developing embryos inside their bodies until they are fully formed. Unlike mammals, they do not have a placenta to nourish the developing offspring. Instead, the embryos rely on a yolk sac attached to their bodies for nutrition. 

The process is known as ovoviviparity, where the eggs develop and hatch internally, with the baby chameleons emerging fully formed.

Most female chameleons lay varying numbers of eggs in a single grip, depending on the species and individual female. One might lay as few as two eggs, while another could produce up to 50. Female chameleons dig pocketed holes to secure their coming brood, demonstrating their natural knack for preparation.

Incubation times also vary from a relatively short four months to a long 12 months in some species before the juvenile chameleons emerge.

11. The Madagascan Chameleon lives for only 3 months.

Most species have a lifespan ranging from 2 to 8 years, with early life stages marked by swift growth. This crucial first year sets the stage for chameleons to acquire unique physical traits and adaptability. Within months, chameleons mature sexually and display a remarkable drive to preserve their species. 

Throughout their life, chameleons shed skin routinely to accommodate new scales or weight changes. Their life cycle has four key stages: egg, hatchling, juvenile, and adult.

However, the Labord's Chameleon, a species endemic to Madagascar, holds the record for three months shortest lifespan among vertebrates. Fascinating yet poignant, they are also known for the cyclic reality wherein the entire adult population perishes annually after a frenzied season of mating and reproduction.

Despite their short lives, these lizards experience the same rapid growth and development as other species, from juvenile to adult chameleons. 

12. Chameleons come in various sizes.

The smallest species is the Brookesia micra chameleon, measuring just over an inch1. These species are found in Madagascar's forest floors and have excellent navigation skills, which help them in catching and eating insects. Their size makes them blend seamlessly into their surroundings, gaining a critical advantage in evading predators.

Conversely, the Parson's Chameleon is the largest chameleon by weight and can grow up to 27 inches. Similarly, the Malagasy Giant Chameleon or Oustalet's Chameleon (Furcifer oustaleti) is one of the largest chameleons by length. Some specimens have been recorded to reach close to 70cm.

Both of these chameleon species also live in the rainforests of Madagascar. Due to their size, these chameleons survive on a diet of insects and small mammals. They can even eat small birds.

13. People can own chameleons as pets.

You can have a chameleon for a pet, but there are better choices for beginners in reptile care. Their delicate nature demands special attention, particularly regarding lighting, temperature, and humidity. Stress can take a toll on our chameleon friends, making them susceptible to illnesses. 

The most common chameleon pets are the Veiled Chameleon, Panther Chameleon, and Jackson's Chameleon. Each species has its specific care requirements, so would-be owners must do their homework on providing lighting, temperature, and humidity conditions that suit a chameleon's needs. 

For instance, the keep chameleons healthy they need access to ultraviolet (UV) lighting to synthesize vitamin D3 and adequately absorb calcium. Additionally, check any legal restrictions or permits that may apply in your area and comply with local regulations before bringing this reptile into your home.

14. Chameleons face several threats.

One of the most pressing concerns for many chameleons is habitat loss. For example, deforestation, agricultural growth, and urbanization spread shrink their natural environments.

Climate change poses another significant challenge. Increases in temperature and shifts in weather patterns disrupt chameleons' sensitive breeding cycles, forcing some species to adapt to new geographic ranges. This forced migration increases competition for resources with other organisms.

Certain species, like the Tiger Chameleon, are already endangered. Meanwhile, others, like the Drakensberg Dwarf Chameleons and Veiled Chameleons, have relatively stable populations. However, all chameleon species face various conservation concerns, primarily from human activities and environmental factors. 

Numerous conservation efforts are underway to protect these fascinating lizards and their habitats. These efforts include habitat restoration projects and creating protected areas for captive breeding programs to bolster dwindling populations. 

For instance, the Madagascar Fauna and Flora Group works tirelessly to conserve the island's unique chameleon species. Moreover, authorities enforce stricter regulations on the illegal pet trade to halt further exploitation of these vulnerable creatures.
