Helio da Silva, a retired business executive from Brazil, single-handedly planted over 41,000 trees in his hometown of Sao Paolo over the last two decades.

Flying over the Brazilian metropolis of Sao Paolo, it’s tough to miss the 3.2-kilometers-long and 100-meter-wide green strip of trees wedged between two of the city’s busiest roads. It is known as Tiquatira Linear Park, and it is the work of a single man who worked tirelessly for over 20 years in order to transform a previously dilapidated area into an actual jungle within the urban jungle that is Sao Paolo. Originally from the town of Promissao, about 500km from Sao Paulo, Helio da Silva was a successful business executive for many years, but after retiring, he took it upon himself to transform the degraded banks of the Tiquatira River into a green oasis for his community. He started planting trees there in 20023 and hasn’t stopped since.

Baorisa hieroglyphica, also known as the Picasso moth, is a species of moth named after the famous Spanish painter Pablo Picasso because of its unusually artistic wing patterns.

First described by British entomologist Frederic Moore in 1882, the Picasso moth is native to Southeast Asia and Northern India. Like most moths, Baorisa hieroglyphica is a nocturnal insect that feeds mostly on the nectar of various plants. Arguably the most beautiful of the Noctuid moths (Noctuidae family), this stunning-looking insect has been dubbed the most interesting moth in the world. The species’ scientific name ‘hieroglyphica’ refers to the striking geometric lines and shapes on its fore wings, while its common name was inspired by the blotches, strips, and dots of color that hint at the work of a talented painter.

A team of scientists studying freshwater ponds on an Australian island observed a rather peculiar mosquito behavior – when feeding on frogs, mosquitoes would always go for the nostrils.

John Gould and Jose Valdez – the first with the University of Newcastle, in Australia, the other the German Center for Integrative Biodiversity Research – spent three years surveying approximately 60 freshwater wetland ponds on Kooragang Island, in New South Wales, Australia. During their research, they observed and photographed a total of 3977 amphibians, but upon returning to their laboratory and laying out all of their photos, they noticed something intriguing. Out of their thousands of photos, 12 of them showed mosquitoes feeding on various species of frogs, but in all of them, the mosquitoes were sucking blood from the animals’ nostrils.

The blue-tongued skink, a lizard native to the Australian continent, has a rather bizarre defense mechanism – it sticks its bright-blue tongue out to predators and they actually run away, sometimes.

A subspecies of Tiliqua scincoides, the blue-tongued skink is one of only five animals known to have blue tongues, the other being the chow chow dog breed, the giraffe, the Impala, and the Okapi. However, it is the only one known for using this distinct physical feature to intimidate predators. When a blue-tongued skink feels threatened, it will start sticking out its blue tongue rapidly, and the contrasting blue tongue against the pink background of its mouth will actually make some animals think twice before attacking it. It sounds weird, but there is a logical explanation behind this unique defense strategy.

Pterocarpus angolensis, commonly known as wild teak or bloodwood, is a species of tree native to Southern Africa known primarily for the dark red sap it secretes which looks like blood when the tree is cut.

Well-known in tropical Africa, where it is used to make high-quality furniture and musical instruments, wild teak is resistant to termites and has a nice, spicy fragrance. It is also resistant to fire so trees are sometimes planted around structures that need to be protected from flames. But outside of southern Africa, bloodwood is most known for its unique dark red sap. Its resemblance to blood has made some people speculate about the tree’s magical healing powers in blood illnesses, none of which have been proven by conventional medicine.

Wisconsin’s Lake Chippewa is home to a giant floating island that sometimes moves around blocking a critically important bridge and needs to be moved by local boat owners working in unison.

Lake Chippewa, aka the Chippewa Flowage, was created in 1923, by flooding a large swamp. Soon after that, many of the peat bogs started rising to the surface and became perfect growing spots for plant seeds carried by wind and wild birds. As the years passed, plants from grasses to trees began to grow and their roots actually caused these floating bogs to grow. Today, they vary from the size of a parking space to several acres, with the largest of them, the so-called “Forty Acre Bog” on the west side of the lake featuring mature trees. Almost every year, dozens of local boat owners team up to push it away from a bridge connecting the East and West sides of the lake.

The black thighed falconet is no larger than a sparrow, but don’t let its size fool you, as this tiny bird is a ruthless predator capable of killing prey its own size.

Falconets are the smallest birds of prey in the world, with the black thighed falconet (Microhierax fringillarius) and the Bornean falconet (Microphierax latifrons) sharing the title of smallest bird of prey in the world. With bodies only 14 to 16 centimeters long, a wingspan of 27 to 32 cm, and only a few grams in weight, the black thighed falconet certainly doesn’t sound like the most efficient predator, but its cute appearance is even more deceiving. The parakeet-like bird is one of the most adorable you’ll ever see, but don’t let that fool you when it comes to hunting, this thing is a tiny killer.

Amanita phalloides, commonly known as the ‘death cap’ mushroom, has always fascinated scientists both because of its deadly amatoxins and the way it manages to conquer new lands in record time.

The death cap originated in Europe where it grows by burrowing into the roots of European Oak trees and forming a symbiotic relationship with them, but it has somehow managed to colonize every single continent except Antarctica. This impressive feat has been puzzling scientists for years, because of how fast the process seemed to be. Most likely introduced in California sometime in the 19th century, by hitching a ride with soil-potted seedlings from Europe, the poisonous mushroom quickly spread across the US state, from the Bay Area further up the coast, eventually becoming more abundant than in its native Europe. After decades of research, scientists now know how the rapid conquest happened.

The Columbia Basin Pigmy Rabbit is the smallest and perhaps the rarest rabbit breed in the world. It is native to just one part of the Washington State Area, and weighs under 500 grams.

There are plenty of tiny domestic rabbit breeds to choose from if you’re looking for an adorable pet rabbit, but the tiniest of them all is actually a wild breed that doesn’t make a great pet. The Columbia Basin Pigmy Rabbit is skittish and nervous, but the main reason why you’ll most likely never own one is its critically endangered status. The breed was declared extinct in the wild in 2001, when the last 14 specimens were scooped up from their native habitat and put into a captive breeding program.

Epiphyllum Oxypetalum is a popular species of cactus famous for producing large, fragrant, white flowers only one night per year.

‘Queen of the Night’ is only a nickname, but one that fits Epiphyllum Oxypetalum perfectly. Unlike the several species commonly referred to as Night-Blooming Cereus which also bloom at night time, producing large, fragrant flowers over several weeks, Epiphyllum Oxypetalum only blooms one night a year, for a couple of hours, with its large, waxy flowers withering before sunrise. The bloom of a Queen of the Night is a rare event, one that draws crowds of flower enthusiasts to the jungles of Mexico, Central America and the Antilles for a chance to witness it in person.

Saint Malo, a historic French port on the English Channel coast, is famous for having the highest tides in Europe, with breakwater defenses barely keeping giant waves from slamming into residential buildings.

Seeing Saint Malo at low tide and then again at high tide is like looking at two completely different towns. The buildings and the way they are laid out are the same, but the existence of a beach as wide as the eye can see at one point, and the complete lack thereof just a few hours later is truly strange. And not only does the ocean come in hard at high tide, but it’s strong as well, with giant waves pounding against the waterfront and splashing up to the top of exposed buildings.

What do you get if you mix a bird, a squirrel and a lizard? Well, I think you’ll have a tough time finding a better answer than the Great Eared Nightjar.

Seeing a great eared nightjar for the first time, you’d be forgiven for mistaking it for a squirrel or even a lizard. The fact is it kind of looks like a combination of animals, or even a real-live version of Toothless, the dragon from DreamWorks Studios’ hit animation “How to Train Your Dragon“. You could say it’s living proof that birds are more closely related to dinosaurs than reptiles.

Saskatchewan’s Crooked Bush, a small grove of aspen trees that grew in a very unusual way, is a botanical oddity that has fascinated both tourists and scientists for years.

Aspen trees don’t usually grow crooked. Like most other threes, they grow straight up, towards the sun, but not the specimens that make up the Crooked Bush. Located near Hafford, in Canada’s Saskatchewan province, this anomaly is the world’s only known crooked aspen tree grove. The strange appearance of the trees was first observed in the 1940s and it has since attracted thousands of tourists to this place. The advent of the internet only made the Crooked Bush more popular and there is now even a wooden walkway that visitors can use to avoid stepping on new growth.

Scientists have discovered that Temnothorax ants infected by a certain tapeworm parasite can live at least three times longer than their uninfected peers while maintaining a youthful appearance and getting special treatment.

A multi-year scientific study published in May of this year has revealed a phenomenon worthy of a science-fiction or fantasy blockbuster – a parasitic tapeworm that grants its host eternal youth while making them irresistible to their uninfected peers, who work harder just to bring them food and fulfill their every wish. It sounds unreal, but scientists at the  Johannes Gutenberg University in Mainz, Austria have studied colonies of Temnothorax ants and found that when they are infected with the tapeworm Anomotaenia brevis, they become virtually immortal.

Temnothorax-nylanderi is a relatively common species of small ants that live in forests throughout Central Europe. They form small colonies on the forest floor, inside acorns or wooden branches, and most importantly, they serve as an intermediate host for the tapeworm Anomotaenia brevis. Up to 70 parasitic larvae can survive in the hemolymph, the body fluid of insects, but instead of competing for resources with their hosts and slowly killing them, the parasites appear to extend their lives considerably, possibly even indefinitely.

Viral photos of a leopard and a cow cuddling somewhere in rural India tell the unique love story between two very unlikely friends.

Cows and leopards are usually not the best of friends, with the latter sometimes preying on bovines to survive. However, you wouldn’t even be tempted to think that looking at a set of viral photos that have been doing the rounds on social media for nearly two decades now. They show an adult leopard cuddling and playing with a cow, which, if the accompanying caption is to be believed, adopted and breastfed the feline as a cub. The story behind the photos has been exaggerated over the years to attract even more attention, but the photos are real and the relationship between the two animals is a testament to the fact that miracles can happen.
