New Zealand, Iceland, and Ireland are all known for having no native snake populations. These countries are all islands with significant geographic isolation or climatic conditions that prevented snakes from naturally migrating to them.

New Zealand: This beautiful country is famous for being snake-free. The government is strict about keeping snakes out, banning them even from zoos.

Iceland: This volcanic island in the North Atlantic Ocean never had native snakes due to its cold climate and geographical isolation.

Ireland: Although legend credits St. Patrick with banishing all snakes, the real reason is likely its cold climate and isolation since the Ice Age, which prevented snakes from migrating to Ireland.

Yes, it's true that starfish, or sea stars, have neither blood nor a brain in the way that mammals do.

No Blood: Starfish use a unique system called the water vascular system to circulate nutrients and oxygen throughout their bodies. This system uses seawater instead of blood, pumping it through a network of fluid-filled canals. This mechanism powers their movement and helps them intake nutrients.

No Brain: Starfish lack a centralized brain like mammals or other complex organisms. Instead, they have a nerve ring around their mouth and radial nerves extending into each arm. This nerve structure allows them to coordinate movement, respond to environmental stimuli, and perform basic behaviors without a centralized brain.

Despite these differences, starfish are capable of complex behaviors, such as regenerating lost arms and coordinating movement to capture prey.

• Berezniki's sinking problem is mainly due to collapsing potash mines underground. This has led to the formation of large sinkholes, which can damage roads and railways.


• During the Soviet era, Berezniki was built on top of a potash mine, which seemed fine at the time. But people started digging too much potash out of the ground, making it hollow underneath the city. They kept digging, which led to the ground becoming unstable and the city sinking.


• Because of this constant excavation, huge pits formed under the surface, turning into underground caves. The roofs of these caves were held up by pillars made of salt. In 2006, something unexpected happened—a freshwater spring started flowing into the mine, around 720 to 1,500 feet deep. This fresh water began dissolving the salt pillars, causing them to weaken, which made the city start to collapse.


• Berezniki provides 10% of the world's potash, so many people depend on these mines for their jobs. The problem is, if the mines close, many people in Berezniki could lose their jobs. The city's sinking has not only caused a safety risk but also threatens the livelihoods of many families. In 2019, about 12,000 people had to move out of Berezniki.

Jakarta, Indonesia:Jakarta is one of the fastest-sinking cities in the world. Some parts of the city are sinking by up to 10-25 centimeters per year, leading to severe flooding and other risks. This sinking is attributed to excessive groundwater extraction and the city's location on unstable alluvial soil. Northern Jakarta has already sunk by more than 2.5 meters over the past few decades, resulting in frequent flooding and prompting the government to plan the relocation of the capital to East Kalimantan on Borneo island.

Following are some more cities experiencing this phenomenon :-

Mexico City, Mexico: Mexico City has a history of significant sinking due to extensive groundwater extraction. Built on an ancient lakebed, the city has sunk by as much as 10 meters in some areas since the early 20th century. The rate of sinking varies across the city, with some neighborhoods sinking by up to 30 centimeters annually. This sinking has caused structural damage to historic buildings, roads, and other infrastructure.

New Orleans, United States: New Orleans is sinking at an estimated rate of 0.5 to 1 inch (1.27 to 2.54 centimeters) per year. The city's low elevation, combined with land subsidence due to natural factors and human activities like oil and gas extraction, contributes to its sinking.

Venice, Italy: Venice has been sinking for centuries, partly due to the compaction of the ground and the extraction of groundwater in the surrounding region. The city sinks at a rate of approximately 1-2 millimeters per year, though this can vary. Venice's sinking, combined with rising sea levels, results in frequent flooding known as "acqua alta." Major engineering projects, such as the MOSE flood barrier system, aim to address these issues, but they remain a significant concern.

Bangkok, Thailand: Bangkok is sinking due to groundwater extraction, urbanization, and the weight of heavy infrastructure. The city is sinking at a rate of 1-2 centimeters per year, with some areas experiencing even faster rates. The low-lying geography of Bangkok and its river-based location contribute to flooding risks, escalated by the sinking problem.

White Truffle (Tuber magnatum)
Region: Found mainly in Italy's Piedmont region, especially around Alba, and in parts of Croatia.
Harvesting: Grows underground in symbiotic relationships with certain tree roots. Harvesting involves trained dogs or pigs to locate them underground.
Price: Between $1,608 and $4,288 per pounds. Can reach prices of several thousand dollars per pound, with some single truffles sold at auction for tens of thousands of dollars.

Here's a list of some of the most expensive mushrooms:

① Black Truffle (Tuber melanosporum)
Region: Commonly found in France, particularly in the Périgord region, as well as in Spain and Italy.
Harvesting: Also grows underground, similar to white truffles, and requires trained animals for harvesting.
Price: Generally less expensive than white truffles, but still among the most expensive mushrooms, with prices ranging from $1,000 to $2,000 per pound, depending on the season.

② Matsutake (Tricholoma matsutake)
Region: Found in Japan, Korea, China, and parts of North America and Europe.
Harvesting: Grows in symbiotic relationships with pine trees. Harvesting is seasonal, with the best specimens picked in the early fall.
Price: Prices can vary, but generally starts from $1000 per pound, depending on quality and origin.

③ Morel (Morchella spp.)
Region: Found in various parts of the world, including North America, Europe, and Asia.
Harvesting: Grows in the wild, often in recently burned forest areas. Harvesting can be challenging due to their unpredictable locations.
Price: Generally less expensive than truffles and Matsutake, but still among the pricier mushrooms, with prices ranging from $100 to $300 per pound for fresh morels.

④ Chanterelle (Cantharellus spp.)
Region: Found in various parts of the world, including North America, Europe, and Asia.
Harvesting: Grows in the wild, often in symbiotic relationships with trees. Harvesting can be time-consuming.
Price: Generally less expensive than morels, with prices ranging from $20 to $50 per pound.

⑤ Porcini mushrooms (Boletus edulis), also known as ceps or penny buns
Region: Found in various parts of the world, including Europe, North America, and Asia. They are especially common in Italy and France.
Harvesting: Porcini mushrooms grow in symbiotic relationships with trees, such as pines and oaks, often in forests. They can be found both in the wild and through cultivation, though wild specimens are more sought after.
Price: Porcini mushrooms are generally less expensive than truffles and Matsutake, but their prices can vary depending on the season, quality, and origin. Fresh porcini typically range from $20 to $60 per pound, while dried porcini can be more expensive per weight.

The house often called the "most loneliest house in the world" is located on Elliðaey Island, part of the Vestmannaeyjar archipelago in Iceland.

It is a small, isolated structure, originally built in the 1950s by the Elliðaey Hunting Association, a group of locals who used the island for hunting puffins and other birds. The house was intended as a lodge for the hunters to use during their expeditions.

The island is uninhabited, and the house has no modern conveniences like running water or electricity. Its remote setting and lack of nearby settlements have contributed to its reputation as the loneliest house in the world.

Despite its appeal, access to the island is restricted, and visitors usually need special permission to land. Most tours only allow for viewing from a distance by boat.

The average distance between the Sun and the Earth is approximately 149.6 million kilometers. Given the speed of light, which is about 299,792,458 meters per second, it takes about 8 minutes and 20 seconds for sunlight to travel this distance and reach the Earth's surface.

Every second, the Sun fuses about 620 million metric tons of hydrogen into helium, releasing energy equivalent to billions of nuclear bombs.

Though we often picture the Sun as yellow or orange, its actual color is white, as it emits light across the entire visible spectrum.

These frogs are typically found in tropical rainforests in Central and South America.

Poison dart frogs are known for their potent toxicity, which comes from the alkaloids in their skin. These toxic compounds can be deadly to predators and are used by some indigenous Amazonian tribes to coat blowgun darts for hunting.

In the wild, they primarily eat small insects and ants, which contribute to the toxins they produce.

Among the many species of poison dart frogs, the Golden Poison Dart Frog (Phyllobates terribilis) is considered one of the most poisonous animals on Earth. A single frog can produce enough toxin to kill 10-15 adult humans.

Unlike many amphibians, some poison dart frog species exhibit complex parental care, with males or females carrying tadpoles on their backs to different water sources for development.

The unique alkaloids found in poison dart frog toxins have drawn interest from medical researchers. Some compounds in these toxins have been studied for their potential applications in developing painkillers, muscle relaxants, and other pharmaceuticals.

The Barbados Threadsnake, also known as Tetracheilostoma carlae, is the world's smallest snake. It measures about 4 inches (10 cm), are not venomous and is native to the Caribbean island of Barbados.

Barbados threadsnakes are blind and primarily feed on small invertebrates, with a particular focus on ants and termites.

The Dead Sea's high salt concentration (about 30% to 35%) makes the water denser than usual, causing objects and people to float. This high buoyancy makes it nearly impossible for people to sink or drown in the Dead Sea. The Dead Sea is far saltier than the ocean, where typical salinity is around 3.5%.

The Dead Sea is located in the Middle East, in the Jordan Rift Valley. It forms part of the border between Jordan on the east and Israel and Palestine on the west.

The Dead Sea contains a variety of minerals like magnesium, potassium, calcium, and bromide. These minerals are known for their potential therapeutic benefits and are often used in cosmetics and skin care products.

Due to its high salinity, there are no fish or aquatic plants in it. Hence the name "DEAD SEA".
