Picture yourself exploring the lush tropical forests of Africa, Asia, or Australia when suddenly you come face-to-face with a creature as long as a school bus. That's what happens when you stumble upon a reticulated python (Python reticulatus).
These snakes are the longest and largest among the python species, with some measuring up to 32 feet. The Burmese pythons (Python bivittatus) are almost as impressive, which typically reach lengths of 16 to 23 feet, just a bit shorter but equally large.
But these giant snakes aren't just about their size. You'll be amazed by their colorful skin patterns. Each python has its unique colors. Most pythons have spots, stripes, and speckles, which they use to blend into their surroundings almost perfectly.
Pythons have several names. Each name reflects something unique about the python, whether it's a physical trait or the region they call home. Consider the Ball pythons, also called Royal pythons. It's an odd name for a snake, but it perfectly captures its tendency to curl into a tight ball when feeling threatened.
This little snake hails from sub-Saharan Africa, and although it's the smallest species on the continent, its name is undoubtedly a big conversation starter.
Now, let's journey to Southeast Asia, where we encounter two remarkable species: Burmese pythons, known for their immense size, takes its name from its homeland, Burma (now Myanmar), and the reticulated python, which got its name from its appearance. 'Reticulated' describes something resembling a net or network, perfectly describing the intricate pattern adorning this python's skin.
One of the most impressive python facts is their ability to swallow meals that are larger than them. Pythons are skilled predators with diverse appetites. They hunt a wide range of prey, although these snakes prefer small to medium-sized mammals like rats, rabbits, and opossums. Contrary to popular belief, pythons don't attack humans unless provoked or stressed. Moreover, they don't limit their diet to mammals.
Pythons also readily devour birds of various sizes, from small sparrows to larger ducks and chickens. However, larger pythons, such as the reticulated and African rock python, can take on even larger prey like deer and antelopes.
The secret to their thriving dining is their great jaws, which can stretch wide. A stretchable ligament holds together the python's lower jaw, which, unlike most animals, isn't fused. Furthermore, its upper jaw isn't tightly stuck to its skull, allowing it to move independently and reach a 180-degree angle.
Combined with their slow metabolism, pythons can sustain themselves for weeks or months after consuming a large animal.
Like most snakes, pythons are oviparous reptiles, laying eggs for reproduction. Unlike some snakes that give birth to live young, pythons rely on developing their offspring within eggshells.
Once a python mother lays her eggs, she becomes a vigilant protector. She coils her formidable body around the clutch of eggs, creating a protective shield until the eggs hatch. This strategy protects the eggs from potential predators and plays a crucial role in their survival through a fascinating process known as "shivering thermogenesis."
The mother python can warm her eggs during this process by voluntarily causing her muscles to shiver. This muscle contraction generates heat, acting as a natural incubator that aids in developing the eggs.
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.

Rose Edouard or the panneer rose. Shobha Menon Mongabay India
Assa · 2023 ago
The entrancingly sweet fragrance of the panneer roja jogs my memories of my beloved aunt accessorising my plait with enchanting blooms from her suburban rose garden. Honey bees love them too: why else do they swoon into the languorous curls in the panneer rose heaps and not in other fancy coloured pouters?
Our flower vendor Manju said assertively, “Ithu thaan original [This is the original one]”. And so, I embark on a delightful journey with the panneer/Thanjavur rose or the Rose Edouard, a topper on India’s “heritage scents” list.

Cute and frisky, Arctic foxes are nomadic animals that follow polar bears onto the ice in search of food throughout the winter. During the summer they form family groups. The mother and father both care for the young and sometimes a female kit from a previous litter joins in to help care for the new pups. In the wild, Arctic foxes only live for 3-4 years, as there are many predators to evade, including eagles, polar bears, wolverines, red foxes and wolves.
If you’ve seen the classic photo of an Arctic fox nosediving into the snow, they aren’t playing, they’re hunting. Their hearing is so good they can hear lemmings moving underneath the snow. They pounce when they get close.

One interesting fact about beetles is that they use a form of pollination known as "mess and soil" pollination. Unlike bees and butterflies, these insects can eat all parts of a plant, from pollen and other floral tissues to even the bark of trees. They even poop within the flowers.
They are the primary pollinators of primitive flowering plants like cycads, magnolias, and water lilies. These plants often have large, bowl-shaped, or cup-shaped flowers that are more open and accessible to beetles than those targeted by bees or butterflies.
A purple carrot is particularly rich in antioxidants that fight inflammation and have the same nutrient value as an orange carrot. History shows the first usage of purple carrots dates back to the 10th century in the Iranian Plateau and Persian Empire.
Like an orange carrot, it contains B vitamins, vitamins C and A, fiber, manganese, and potassium. It also has antioxidants that protect your body from oxidative stress, an imbalance between reactive molecules and antioxidants. These antioxidants include chlorogenic acid, caffeic acid, and anthocyanins.
Purple cabbage is often known as red cabbage. The vegetable is part of the Brassica genus of plants. Red cabbage has the same taste profile as green cabbage, but red cabbage has a more prominent nutrient profile.
Like other purple vegetables, anthocyanins are responsible for the cabbage’s purple color. It has high vitamin C and low-calorie content. It contains small amounts of iron, calcium, copper, zinc, phosphorus, and magnesium.
Research shows that red cabbage has 4.5 times higher antioxidant content than its green counterpart. It contains kaempferol, carotenoids, and flavonoids.
This purple vegetable is also a good source of a sulfur-rich compound known as sulforaphane. It forms when raw cabbage is cut or crushed. Purple cabbages can improve your heart health because they contain 36 types of anthocyanins.
