7 incredible animals that change colour — and why they do it
Here are 7 extraordinary animals that change colours:
Crab Spiders, also called flower spiders area species of spider that change colours. According to the WIRED Magazine, they can shift between white and yellow to camouflage while ambushing prey on flowers. However, many researchers claim that this color change does not necessarily increase their hunting. The reason for color change remains uncertain.
This species of octopus are remarkable for color changing abilities. These species use specialised skin cells called chromatophores to alter their appearance. They change their color to camouflage, communicate and stay away from predators. According to National Geographic, these changes are controlled by the nervous system, which allows octopuses to blend seamlessly in their surroundings.
As per National Geographic, Cuttlefish are known for rapidly changing colour and texture using chromatophores. This helps them to blend into their environments and communicate. They can evaluate the hue, contrast, and feel of their environment and replicate it within moments, even when there is no light. This skill helps them in evading predators and in catching prey.
According to WIRED, chameleons change colour for thermoregulation and communication rather than camouflage contrary to popular belief. They modify their skin pigmentation to either absorb or reflect heat, helping with temperature control. Moreover, shifts in color communicate messages to other chameleons, indicating dominance or readiness to mate.
The golden tortoise beetle displays a remarkable shift in colour from bright gold to muted brown or red when threatened. This alteration occurs because fluids shift within its elytra (the covers of its wings), which influences how light is reflected. This change in color might function as a defense strategy, shocking potential predators or indicating that it is not edible.
Pacific tree frogs have the ability to alter their skin colouration from green to brown and back again over the course of several hours or days. According to Earth.com, this ability in them helps to blend into varying environments, camouflage and stay away from predators. The alteration in color is affected by elements such as the background hue, brightness levels, and temperature.
Flounders have the incredible capability to modify the colour and pattern of their skin to blend in with the sea floor, assisting in their camouflage. They accomplish this through unique skin cells known as chromatophores, which can expand or contract to change their color. This adaptation allows them to evade predators and surprise their prey.

Stop squishing ants — here's what happens when you do
It may feel very satisfying when you squish an ant as a quick solution to your pest problem, but you're actually making things worse. Ants don't randomly wander into homes, they're methodical scouts on a mission. These insects send out forager ants to explore territory in expanding circles from their colony, searching for three essentials: food, water, and shelter. When a scout discovers a promising location, it leaves an invisible pheromone trail as it returns to the nest, essentially creating a chemical highway for other ants to follow. Common entry points include cracks around windows and doors, gaps in foundations, utility line openings, and even microscopic spaces in walls. Once inside, it can become hard to get rid of them. While many are aware of taking care of the ant problem through different menthods, one common mistake is overlooked: squishing them. Understanding what happens when you crush these intruders reveals why this common response backfires spectacularly. When you squish an ant, you're not just ending one insect's life — you're sending out a chemical distress signal. According to National Geographic, 'Throughout its life, an ant uses chemicals in its skin to automatically send out a message to its nest-mates, saying 'I'm alive. Don't throw me out.'' When they are crushed, they release alarm pheromones that serve as both a danger warning and a dinner bell for their colony mates. These chemical messengers tell nearby ants that something has happened in this location, often interpreted as a sign of potential food or threat that requires investigation. This biological alarm system means that within hours of your squishing spree, you'll likely see even more ants marching toward the very spot where you thought you solved the problem. Squishing ants one by one is fundamentally ineffective because you're fighting symptoms, not the source. Eliminating a few scouts doesn't impact the queen or the nest's reproductive capacity. Moreover, ant colonies operate on a replacement system. When workers don't return, the colony simply sends more to investigate and continue the food-gathering mission. Seal entry points: Prevention beats reaction every time. Use caulk to close cracks around windows, doors and foundation areas where ants typically enter homes. Eliminate attractions: Store food in airtight containers, clean up crumbs promptly, fix water leaks and remove standing water. No food source means no reason for ants to visit. Natural deterrents: Citrus peels, white vinegar or cinnamon can create barriers that ants prefer to avoid, offering a gentler approach to ant management. Remember, ants play crucial ecological roles as decomposers and soil aerators. Rather than viewing them as enemies to be crushed, consider them indicators of conditions of the home you can control. Most ant problems stem from accessible food and water sources that you can manage easily.

What's bigger than an anaconda? This 58-million-year-old fossil of prehistoric snake in Colombia may have the answer
Source: WIRED In a groundbreaking paleontological discovery, scientists have uncovered fossil remains of a prehistoric snake that challenges everything we know about reptilian evolution. Called Titanoboa cerrejonensis , this extinct serpent lived over 58 million years ago and is now recognised as the largest and heaviest snake ever found. Stretching up to 14 meters in length and weighing over a tonne, Titanoboa dwarfs today's anaconda and python species. Its discovery in Colombia's Cerrejón coal mine offers rare insight into ancient ecosystems, tropical climate conditions, and the scale of prehistoric megafauna. This astonishing find reshapes our understanding of prehistoric snakes and their dominance after the dinosaurs. World's biggest snake fossil found: Meet Titanoboa, the 58-million-year-old giant The Titanoboa cerrejonensis is a now-extinct species of snake that thrived during the Paleocene Epoch, a critical period in Earth's history that followed the extinction of the dinosaurs. What sets Titanoboa apart is not only its enormous size but also the insights it offers into the evolution of reptiles, prehistoric ecosystems, and ancient climates. According to BBC reports, this species was virtually unknown to science until 2009, when fossils were unearthed at the Cerrejón coal mine in northern Colombia . The discovery has since transformed our understanding of reptilian evolution and the tropical environments that emerged in the wake of mass extinction. Source: BBC Where and when did Titanoboa live Titanoboa roamed Earth between 58 and 60 million years ago, during a time of ecological recovery after the dinosaurs vanished. Its remains were found in what was once a humid, swampy rainforest—now the Cerrejón mine. This site has become a treasure trove for paleontologists studying the Paleocene, revealing a rich diversity of early tropical life. The ancient rainforest, teeming with warmth and moisture, offered the perfect environment for cold-blooded animals like Titanoboa to grow to such extraordinary sizes. Titanoboa: Size and weight According to scientific estimates, Titanoboa cerrejonensis reached lengths of up to 13–14 meters (42–46 feet)—about the size of a modern school bus—and weighed over one metric ton. In comparison, the green anaconda, often considered the largest living snake today, rarely exceeds 6 meters in length and 250 kg in weight. This makes Titanoboa not only the largest snake in the world but also a true apex predator of its time. Source: Smithsonian Magazine Titanoboa hunting strategy: A predator without venom Unlike venomous snakes, Titanoboa killed its prey using constriction. It would coil around its target whether a mammal, reptile, or fish and squeeze until the animal suffocated. Once its prey was immobilized, the snake would swallow it whole, starting with the head. This mode of predation is similar to how modern boas and pythons hunt, showing that despite its size, Titanoboa's feeding behaviour followed well-known biological strategies. Titanoboa diet Initially, scientists assumed Titanoboa fed on large land mammals. However, further analysis of its jawbones revealed loose teeth—a feature uncommon in meat-eating snakes but typical of aquatic feeders. This surprising anatomical trait indicated that Titanoboa was a semi-aquatic snake, likely residing in rivers and lagoons, feeding primarily on large fish. This also places it in ecological comparison with today's green anaconda, which exhibits similar behaviour and habitat preference. Climate clues hidden in Titanoboa's biology As a cold-blooded reptile, Titanoboa depended heavily on external heat to regulate its body temperature. Its massive size would have required consistent warmth, suggesting that the climate during the Paleocene was significantly hotter than it is today. Estimates show the average temperature in its habitat was between 86°F and 93°F (30°C–34°C)—a level of heat crucial for sustaining such a giant prehistoric snake. Why the discovery of Titanoboa matters The discovery of Titanoboa cerrejonensis is far more than just an awe-inspiring tale of a giant snake. It provides crucial insights into: The evolution of reptiles after the extinction of dinosaurs The climate conditions that allowed such massive cold-blooded creatures to thrive The biodiversity and structure of early tropical ecosystems Also Read | Scientists discover a 'second Earth' twice the size of our planet near a red dwarf star, 154 light-years away
