Pit vipers and similar snake species possess heat-sensing pit organs located between their eyes and nostrils. These specialised organs detect infrared radiation, allowing snakes to "see" the body heat of their prey. This thermal detection enables them to hunt effectively in the dark, striking with lethal precision.
5. Dogs: olfactory champions
Dogs boast one of the most powerful senses of smell in the animal kingdom, with up to 300 million olfactory receptors compared to a human's six million. They can track scents over vast distances and even detect medical conditions like diabetes and cancer, making them invaluable partners in search and rescue, detection, and therapy.
6. Moths: Extraordinary smellers

The male silk moth (Bombyx mori) has a highly specialised sense of smell, capable of detecting a single molecule of a female's pheromone from miles away.
This remarkable ability ensures the survival of their species by guiding males to mates over great distances.
7. Dolphins: Acoustic navigators

Dolphins utilise echolocation to perceive their surroundings underwater. By emitting clicks and interpreting the echoes that bounce back, dolphins can locate objects and prey with astonishing precision. Their hearing range extends up to 150 kHz, vastly exceeding the human limit of 20 kHz, aiding them in hunting, communication, and navigation.
8. Catfish: The taste-all-over body

The platypus is one of the few mammals that can detect electric fields. Its bill is equipped with electroreceptors that sense the weak electrical signals produced by the muscle contractions of prey.
This adaptation enables the platypus to forage successfully underwater with its eyes, ears, and nostrils closed.
10. Owls: Silent hunters of the night

Owls have adapted to nocturnal life through a combination of acute hearing and silent flight. Their facial discs funnel sound to their asymmetrically placed ears, providing precise directional hearing. Special feather adaptations enable them to fly silently, allowing them to approach prey undetected.
11. Sharks: Masters of electroreception
Image: National Geographic
Sharks possess specialised electroreceptors called ampullae of Lorenzini, enabling them to detect the faint electrical fields generated by other organisms. This ability allows sharks to sense prey hidden under sand or swimming in total darkness, even detecting the heartbeat of their quarry.
12. Elephants: Seismic communicators

This animal's punch is faster than a bullet
The ocean is home to wonders of form, function, and survival. These creatures defy our expectations with their strength, sight, and strategies. Among them, the mantis shrimp stands out as a marvel of evolution: a small but formidable crustacean that wields lightning-fast strikes, sees with extraordinary precision, and inspires scientists with its ingenious design. Mantis shrimp belong not to the shrimp family but to the ancient group of crustaceans called stomatopods, which split from other Malacostraca more than 400 million years ago. Today, scientists recognise over 500 species worldwide, many inhabiting burrows in tropical and subtropical reefs, according to the National Geographic. These colourful invertebrates range from under an inch to nearly a foot long. One well-known species, the peacock mantis shrimp (Odontodactylus scyllarus), typically reaches 10–18 cm and impresses with neon blues, fiery reds, and greens, camouflaging amid coral and serving as a warning to others. They build and defend burrows, doubling as shelter and ambush stations. Mantis shrimp of the 'smasher' category strike with a club-like appendage that unleashes blows comparable in speed to a .22-caliber bullet—around 23 m/s (50 mph), as per the National Geographic. Equipped with a 'saddle'-shaped spring that stores elastic energy, plus a latch mechanism, they generate accelerations up to 10,000 g—captured in super‑slow‑motion footage. On impact, their strike creates cavitation bubbles, microscopic vapor pockets that collapse, producing shockwaves and even flashes of light, amplifying the destructive force. This combo enables the shrimp to shatter the shells of prey and even aquarium glass. The mantis shrimp's club is a layered marvel. Its outermost layer, rich in crystalline hydroxyapatite, is extremely dense and resists damage. Beneath it, gradations of minerals and polymers absorb shock and protect the structure from fracturing under repeated blows. Their eyes may be the most complex in the animal kingdom. Each eye moves independently and offers trinocular vision. They perceive 12 to 16 types of photoreceptors, including ultraviolet, infrared, and polarized (even circularly polarized) light, which are sensitive to signals that human eyes cannot detect. Such advanced vision may aid in hunting, navigating complex reef environments, communicating subtly, or detecting prey and rivals. Research using a robotic proxy called 'Ninjabot' revealed that mantis shrimp vary their strike strategy when hunting snails, targeting the snail's opening or tip depending on shell shape, WIRED reported. This shows behavioural sophistication beyond brute force. Engineers have replicated aspects of the mantis shrimp's punch mechanics using synthetic saddle structures and bio-inspired materials with Bouligand layering and ceramic-polymer bilayers. These designs promise applications in body armor, aerospace, robotics, and self-healing materials.

Want to live past 100?: 5 simple secret habits from the world's longest-living people in 'Blue Zones'
What if the secret to living longer doesn't lie in expensive diets or intense workouts, but in just living, and coincidentally shared across distant corners of the globe? Surprisingly, that is the secret behind the concept of Blue Zones, regions where people often live past 100. And this is no miracle; instead, it's about the simple ways of living through everyday life. 27:30 Senior Living in India-- Myths, Realities & the Future of Purposeful Ageing What are Blue Zones Dan Buettner, an American author, explorer, storyteller, and longevity researcher, had gone on a National Geographic expedition and which surprisingly turned into a major discovery about living a longer, healthier life. Buettner and his team, which is made up of scientists, anthropologists, and demographers, set out to explore regions where people regularly live to be 100 or more. They eventually identified five such places around the world, now known as 'Blue Zones', which include Loma Linda in California, Nicoya in Costa Rica, Sardinia in Italy, Ikaria in Greece, and Okinawa in Japan. What these places had in common wasn't just luck or good genes. In fact, according to the Danish Twin Study, only about 20% of our lifespan is determined by genetics; the rest is defined by our daily habits and lifestyle choices. Buettner and his team studied the people in these regions and found they shared some key lifestyle traits, these included things like natural movement, a sense of purpose, low stress, plant-based diets, and strong social connections. Here are 5 simple secrets to a long and healthy life, inspired by people living in the world's 'Blue Zones,' according to the study 'Blue Zones, Lessons From the World's Longest Lived', published in the National Library of Medicine Move naturally People in Blue Zones don't depend on gyms or intense workouts to stay fit. Instead, their daily lives are full of natural movement. They walk often, garden, do housework by hand, and use minimal modern conveniences. This constant, gentle activity keeps them physically active without needing to 'exercise' in the traditional sense. Their environments are designed to encourage constant movement by walking, which supports joint health, mobility, and strength well into old age, which makes a big difference over time. Have a sense of purpose Knowing why you wake up each day can add years to one's life. In Okinawa, this concept is called Ikigai, and in Nicoya, it's plan de vida. Both mean having a clear purpose or goal that brings meaning to one's daily routine. Whether it's taking care of family, taking up a hobby, or contributing to the well-being of those around, this sense of direction helps people stay mentally and emotionally balanced. Research published in Science Daily shows that people with a strong sense of purpose have about a 20% lower risk of death over seven years. Manage stress through daily routines Even people in the world's healthiest regions experience stress, but they've found simple ways to manage it. Residents in Blue Zones have daily rituals to reduce tension, like napping, praying, reflecting on ancestors, or gathering socially. These small habits help lower stress hormones and inflammation, both of which are linked to chronic diseases. Rather than letting stress build up, they dedicate downtime regularly. This keeps their minds clear, their bodies calm, and contributes to the emotional stability that supports a longer, healthier life. Eat until you're 80% full People in Blue Zones don't overeat. In Okinawa, they follow a 2,500-year-old saying, 'Hara hachi bu', which reminds them to stop eating when their stomach is about 80% full. This helps prevent weight gain and digestive problems. They also tend to eat their last and smallest meal in the late afternoon or early evening and avoid snacking later. By maintaining portion control and listening to their body's signals, they naturally reduce calorie intake, which is also one of the most effective ways to slow aging and extend life. Focus on plant-based diets Centenarians in Blue Zones eat mostly plant-based foods. Their meals are rich in beans like black, fava, soy, and lentils, along with vegetables, whole grains, and nuts. Meat is eaten rarely, usually just a few times a month, and in small portions, roughly the size of a deck of cards. This 'plant slant' diet provides essential nutrients, promotes gut health, and helps reduce the risk of chronic diseases.

The real orca attack video, watch killer whale ripping apart its target; this one isn't fake like the Jessica Radcliffe and Marina Lysaro clips
After AI-generated fake videos of marine trainers Jessica Radcliffe and Marina Lysaro being killed by orcas went viral on social media, the killer whales have grabbed eyeballs. Orcas are considered highly intelligent and social predators that are found in seas and oceans worldwide. They are usually not seen as a major threat to human beings; however, most fatal cases involving orcas have taken place in captivity. They were named killer whales by ancient sailors who observed their groups hunting and preying on larger whale species, according to Whale & Dolphin Conservation USA. They referred to orcas as ballena asesina in Spanish, meaning killer whale.

They have a competition in the form of great white sharks . The two ocean giants may seem to carry some similarities, but they are very different in the way they go about their business in the water. The viral videos claiming that orcas killed two marine trainers might have turned out to be fake, but there are several videos present all over the internet that suggest how brutal the killer whales are when it comes to ripping apart their targets. Watch a video shared by National Geographic showing how an orca defeated a great white shark Live Events Orcas vs Great white sharks Orcas and great white sharks are both ocean dwellers. Amid all the apex predators underwater, these two stand out as the most formidable forces. They are known for ruling their respective domains with unmatched prowess. While great whites prefer warmer temperatures, orcas thrive in cooler water. However, there have been times when both were seen in the same region. According to Discover Magazine, orcas, the killer whales, are stronger, bigger, and smarter, and can swim faster than great white sharks; hence, they outmatch the white sharks. Orcas are the largest members of the dolphin family. They are easy to recognize due to their distinctive black and white coloration and towering dorsal fin. On the other hand, great white sharks are known for their streamlined bodies, grey coloration, and rows of serrated teeth. As far as the diet is concerned, orcas are versatile eaters. They consume a variety of prey, including fish, seals, and even other whales, while great white sharks primarily feed on marine mammals like seals and sea lions. Orcas live in close-knit groups called pods. They use a complex system of sounds to communicate. Great white sharks tend to be lone hunters, quietly creeping up on their prey. Orcas have a longer life span compared to white sharks. The killer whale can live up to 90 years, while white sharks have a lifespan of about 70 years. Orcas vs Great white sharks: Size comparison Orcas are mammals that live in groups called pods. These carnivorous animals can grow to be between 23 and 32 feet long and weigh up to 6 tons. Great white sharks are born measuring about 1.2 m (3.9 ft) and have a growth rate of about 25 cm (9.8 in) every year, according to Shark Divers. Larger Great White females can grow up to 6.1 m (21 ft) in length and weigh in at over 2,000 kg (4,500 pounds) at maturity, according to National Geographic.
