As apex predators, pythons maintain the delicate balance of ecosystems. Their primary contribution lies in controlling the populations of rodents and other small creatures, which is no small task considering their rapid breeding rates.
Their insatiable appetite is a natural barrier against an unchecked explosion of rodent populations, preventing ecological imbalance. Rodents are notorious disease carriers, transmitting Lyme disease, leptospirosis, and even the plague.
By regulating rodent populations, pythons unintentionally help curb the spread of these diseases, promoting healthier and balanced ecosystems.

The ability to sense infrared thermal radiation evolved independently in three different groups of snakes, consisting of the families of Boidae (boas), Pythonidae (pythons), and the subfamily Crotalinae (pit vipers). What is commonly called a pit organ allows these animals to essentially "see" radiant heat at wavelengths between 5 and 30 μm. The more advanced infrared sense of pit vipers allows these animals to strike prey accurately even in the absence of light, and detect warm objects from several meters away. It was previously thought that the organs evolved primarily as prey detectors, but recent evidence suggests that it may also be used in thermoregulation and predator detection, making it a more general-purpose sensory organ than was supposed.
World Snake Day raises awareness about snakes' complex and essential function in nature. They are responsible for controlling rodent and pest populations, which helps prevent crop damage and the spread of diseases. Many snakes are also the food source of other snakes, mammals, and birds of prey.
Because of their role in maintaining ecological balance, the snakes' presence indicates a healthy environment. Even though snakes live almost anywhere, they face habitat loss. The driving forces are rapid urbanization, deforestation, and human encroachment. Additionally, fear and misconceptions about snakes contribute to unnecessary killings.
In addition to dispelling myths, World Snake Day also illuminates the global snakebite crisis, particularly in rural parts of Africa, Asia, and Latin America.
Limited access to antivenom treatments and medical facilities poses a serious public health issue. This day advocates for improved healthcare measures and raises awareness among communities near snake habitats.
Snakes' flexible jaws allow them to swallow prey much larger than their head. Some large snakes can even eat cows and crocodiles.
A few species also carry potent venom. For example, the King Cobra is the world's largest venomous snake, reaching 18 feet long.
These creatures have transparent scales, called "brilles," instead of eyelids, which shed along with their skin during molting.
A snake's forked tongue is part of a sensory organ known as Jacobson's organ, which enables them to track their prey using chemical cues.
They can sense vibrations through their jaws, which travel to their inner ear, allowing them to detect prey and potential threats.
The IUCN reported four extinct snakes and over 400 snake species as either critically endangered3, endangered, or vulnerable.
According to a report by TRAFFIC, there were 292 recorded seizures from 2012 to 2021 in Southeast Asia2. The confiscations included 17,589 individual snakes and 76,476 whole skins, skin pieces, and other parts.
Another study published in 2019 suggested that unchecked global warming could result in 73.6% of oviparous and 67.6% of viviparous snake species losing half their original range in the Brazilian Atlantic forest by 20801.

1. What is World Snake Day?
Every July 16, this annual event aims to raise awareness about snakes and their conservation.
2. Why should we celebrate World Snake Day?
Snakes play a critical role in nature. They control rodents and other prey populations and maintain ecological balance. Moreover, scientists have begun studying snake venom for its use in developing various medicines, such as drugs for high blood pressure.
3. How can I help protect snake populations?
You can avoid killing them, support conservation efforts, and spread awareness about their importance.
4. Are all snakes dangerous?
Not all snakes are dangerous. Most snakes are non-venomous.
5. What should I do if I encounter a snake?
If you encounter a snake, stay calm, give it space, and slowly back away. Snakes will usually retreat if given the chance.
The Eastern Diamondback Rattlesnake is the largest species of rattlesnake in the Americas and the heaviest venomous snake.
It can grow to a maximum length of eight feet and has diamond-shaped dark brown, black, and yellow markings. Its head is triangular, with a dark stripe running through each eye.
They use their rattle at the end of their to hunt prey. Rattlesnakes of this kind are solitary creatures that seek out other rattlesnakes only during the breeding season.
The Western Diamondback Rattlesnake is a rattlesnake living in the arid landscapes of the Southwestern United States and Northern Mexico. It is known for its diamond-shaped patterns and robust size, reaching up to 4 feet.
This type of rattlesnake earns its "coon tail" nickname due to its distinct tail pattern. The black and white banding resembles a raccoon's tail, hence the moniker.
The snake possesses a hemotoxic venom but uses it only when necessary. It is defensive and warns with its rattles before striking.
The snake is more active during cooler hours and feeds on small mammals, birds, lizards, and other snakes.
The Mojave Rattlesnake is a venomous snake in the southwestern United States and central Mexico.
Mojave Rattlesnake bites contain potent neurotoxins that can cause paralysis and death. However, the snake is not aggressive and will only strike if threatened.
