3. Lasiodora parahybana (Pink Salmon Bird-eater)

It is one of the largest spiders in Brazil. It has a pink coloration and a calmer behavior. It usually feeds on crickets, beetles, and small vertebrates. Despite its size, it is not aggressive toward humans.

4. Pterinochilus murinus (Orange Baboon Spider)

Habitat: East and Central Africa
Size: up to 15 cm in wingspan

Known for its vibrant color and explosive reactions, this spider does not hesitate to attack when threatened. Its bite is painful, but rarely dangerous. It is highly valued by experienced breeders.

5. Poecilotheria rajaei (Giant Sri Lankan Spider)

Habitat: Forests of Sri Lanka
Size: up to 20 cm in wingspan

It lives in holes or hollow trunks and is active at night. It has a gray color with black markings, feeds on insects and small lizards. It is discreet and reclusive, and rarely seen by humans.

A Force in Nature, Not a Danger

Despite their size, the largest spiders in the world are not villains. According to the Smithsonian, their role in ecosystems is essential: they control populations of insects and small animals and help maintain the balance of biodiversity.

These hairy giants show that nature always surprises, even in forms that many prefer to avoid.

Would you have the courage to encounter one of these spiders in the middle of the forest?

A giant printer called the “Ferrari” of concrete has landed in Latin America and can already build a 120-square-meter house in just 48 hours, making the traditional construction site look like something from the last century.

Brazil will harvest a record crop of up to 357 million tons of grains, but it does not have the capacity to store a large part of it. The storage deficit has reached the highest level in history and is equivalent to almost the entire production of Argentina.

Four times faster than the Concorde, capable of taking passengers from New York to London in less than an hour at Mach 5.5, and with an engine that switches from turbojet to ramjet mid-flight at Mach 3.5, the Hermeus Quarterhorse went from paper to its first flight in just 19 months.

SpaceX will dock a $843 million vehicle to the International Space Station to push a nearly 420-ton laboratory against the atmosphere and make the debris fall in a controlled manner into the ocean.

China opens the world’s first school where more than 100 humanoid robots from different brands will study together, each movement will be repeated up to 600 times a day and the data will feed a collective brain that will teach all the robots of the future.

A giant golden ball in the middle of gardens in India was assembled with 1,415 discs, took decades to be completed, and transforms sunlight into controlled central lighting.

Three teenagers surprise the world by creating a powder with tamarind seeds that removes microplastics from water, requires no electricity, and wins an international prize of $12,500 at The Earth Prize 2026.

India completes tests of Project Kusha, its own long-range air defense shield to shoot down aircraft and missiles hundreds of kilometers away.

The largest neighborhoods in each state of Brazil are astonishing in size: Campo Grande leads with 352,000 inhabitants, Cidade Industrial exceeds 172,000, and Jorge Teixeira dominates the North.

China prepares a “panoramic Hubble” with 2.5 billion pixels and a field of view 300 times larger: Xuntian will have a 2-meter mirror, resolution close to that of the American telescope, can dock at the Tiangong space station for maintenance, and promises to map 40% of the sky in a decade.
