Also known as the paiche or the pirarucu, the arapaima is one of the most fascinating species of fish in the world. It’s one of the largest freshwater fish in the world, and certainly the biggest in South America, being a native to the Amazon Basin and nearby lakes and swamps. These arapaima are absolutely huge, most spanning 2.5 […]
Not as unique as we thought An “emotionally competent” young ape rushes to hug another juvenile that has just been attacked. I think the idea of animals doing something “like humans” is pretty outdated as it is – so many things that we thought were unique to us have been proven to be if not […]
Through the halls of TedxDetroit last week, participants were introduced to an unfamiliar and unlikely guest – a remote controlled cyborg cockroach. RoboRoach #12 as it was called can be directed to either move left or right by transmitting electrical signals through electrodes attached to the insect’s antennae via the Bluetooth signals emitted by a smartphone. […]
Jellyfish are really impressive creatures, for all their simplicity; now, a new research has shown that the elastic body allows moon jellyfish to travel extra distance at no energy cost. The sockeye salmon is a sleek, muscular torpedo which rams up waterfalls. The jellyfish is a blob, drifting on aimlessly in the oceans. Obviously, the […]
A rare sight to behold, the elusive Pinocchio lizard was finally spotted after a team of researchers and photographers set on a long quest to find it. Their efforts were rewarded as this is only the third time a specimen of this long-nosed lizard was ever reported in nearly the 60 years since its discovery. […]
In a mind boggling act, spiders are capable of “ballooning” themselves using silk strands and fly for miles, both in altitude and distance. Small and big spiders alike can do this, although smaller ones are capable of traveling further, and scientists have long theorized the mechanisms of spider ‘flight’. Peter Gorham at the University of […]
A previously unknown genus of electric fish was discovered in a remote area in South America, very rich in biodiversity but largely unexplored. The Akawaio penak is a thin, eel-like electric fish which inhabits the murky waters of the upper Mazaruni River in northern Guyana. Guyana lies at the northern border of Brazil, and the […]
Biofuels are very ‘hot’ at the moment, as they’ve started to gain traction. Production as increased about 400% since 2000, and that’s a good thing. Right? After all, anything that can replace fossil fuels is a better option. Well, not necessarily. A while ago, I wrote a piece for ZME Science in which listed some […]
According to a post in the Navy Times, training and testing will likely “inadvertently” kill hundreds of whales and dolphins and wound thousands in the next five years. Most of the damage will be done by explosives, though some might come from testing sonar or animals being hit by ships. Rear Adm. Kevin Slates, the […]
Loliginidae, also known as pencil squids, are formidable animals that can change their colour matching their surroundings really fast and effortlessly. For centuries the only thing man has learned from them is how tasty they are. Now, researchers at University of California, Irvine, found there’s much more to them then a simple calamari dish. The scientists […]
Ants are absolutely fascinating creatures. Not only have they discovered farming and animal husbandry thousands of years before us (sometimes even using bacteria to grow gardens), they also conduct executions for the good of the colony, follow Fermat’s principle of least time, and as it has been shown now, draft parasite ants as mercenaries. Just […]
The more researchers study ecosystems, the more we learn that an ecosystem behaves, in many ways, just like a living organism: thousands of years after human hunters wiped out big land animals like giant ground sloths, the ecosystems they lived in are still suffering from the effects, much like a body suffers from past trauma. […]
It’s currently estimated that only 4,510 to 7,350 snow leopards remain in the wild – though estimates rely on outdated information and are pretty rough. Given the development of the local environment, the numbers are probably optimistic. Numerous agencies are working to conserve the snow leopard and its threatened mountain ecosystems which range across Asia, […]
It’s amazing how two different animals from two completely different environments evolve some identical physical features. Take bats and dolphins for instance. Both of them use a complex system that produces, receives and process ultrasonic sound waves in order to identify visually hidden objects, track down prey or navigate through obstacles better – typically this […]
The fat-tailed dwarf lemur, native to the marvelous isolated ecosystem of Madagascar, is the closest human relative known to hibernate. After studying the sleeping behavior of both captive and wild lemur specimens, scientists at Duke University have discovered a great deal about how hibernation works in lemurs. The key discovery is that they can go […]
The Humane Society of the United States (HSUS), recently initiated a bold and creative project in which they enlisted six member organizations of the North American Primate Sanctuary Alliance. HSUS asked the organizations if they would each submit a piece of art made by chimps belonging to their respective sanctuaries. In the end, some pretty creative […]
Many deep sea animals, such as the infamous anglerfish, use parts of their bodies as decoys, to attract unsuspecting prey. Now, researchers have found that a certain squid can do this as well – its tentacle tips flap and flutter as if swimming on their own. Biologists believe that the mesmerizing movement of the tentacles […]
While browsing reddit the other day, I came across a most peculiar finding. One of the users, Decapod73 or Tony Alexander in real life, posted photos he took while on an expedition in the Peruvian Amazon forest of intricate structures that bear an uncanny resemblance to a white picket circular fence – right in the center, half […]
It’s a lazy dog owner’s dream come true. What if you had a remote control that you could use to instruct your dog to perform various household tasks, like say… grab you a cold one from the fridge? Scientists at Auburn University, Alabama have devised a system that makes such a thing possible, although the long […]
Just like we get a tan and our skin gets darker in response to sunlight exposure, whales increase the pigment in their skin as well, but not only do they do this, they also accumulate damage to the cells in the skin as they get older, just like humans. “Whales can be thought of as […]
Honeybees are exquisite and majestic beings, which have always caught the imagination of people. Bees are typically associated with feminine energy, because they are ruled by queens, particularly with the roman goddess Venus. In some cultures, bees also represent wisdom. From a biological point of view however, bees could be definitely associated with motherhood. Without bees, […]
Crows, like most other species from the corvid family (ravens, rooks, etc.), are some of the most intelligent animals on the planet, actually rivaling apes and dolphins. Tool use is common among these birds, but where they shine is in their social and emotional intelligence. For instance, a few years ago I reported how ravens point […]
Farmers, with the help of researchers in the field, have been desperately trying to develop new insecticides that can ward off pests looking to claim their crops. These products work with a varying degree of effectiveness. For one, the insect pests tend to develop tolerance and new solutions have to be developed, and of course […]
It’s clear that humans are now, more than ever, a driving force in evolutionary biology. Early domestication efforts through breeding and training have changed some species to the point that they’ve grown to be as we wanted them to become. The effects of climate change, a great part of which is anthropogenic, actually influence animals […]
Many months later after scientists isolated thousands of samples taken from different bat species found close to the home of the first known victim of the Mers coronavirus – a deadly virus which first emerged in the Middle East last year, killing 47 so far (~50% fatality among infected) – scientists found the evidence of the […]
While in the Amazon, a certain pointy fish that crawls up a certain male organ sends shivers in the spines of potential swimmers, in Scandinavia, another Brazilian fish is threatening the genitals of unsuspecting skinny dippers; it’s not the famed piranha, but its cousin – the Pacu. The Pacu naturally has a small mouth, eating […]
Conodonts – Greek for “having cone-shaped teeth” – are extinct chordates resembling eels, classified in the class Conodonta. These are some of the most primitive vertebrates in recorded fossil history, and are of particular interest to scientists because of their toothlike structures that lend the group its name. For a while it had been unclear how […]
I have never in my life eaten a crab or a lobster, because ever since I was a kid, boiling an animal alive seemed extremely cruel; it just didn’t make sense that an animal doesn’t feel pain – and even today, it doesn’t, to me. Pain is your body’s way of telling you something is […]
Dolphins are simply stunning creatures – they think, and empathize; they have names, hang out in cliques, they talk like humans, and they almost always try to rescue their wounded friends. They can go without sleep for 15 days, and every day they show us that they are simply ‘non human persons’. Now, another research […]
This isn’t a cyborg gold fish from a borg’s aquarium, this little amazing fellow is called Einstein. He unfortunately ended up with a disability caused by a disease that has basically made him useless in water: he can’t swim anymore. Not by itself, at least. Feeling heart broken by seeing his pet fish so helpless, […]
It’s summer, so beach season is naturally in full swing. A lot of people diving trough coastal areas in the Atlantic and Pacific are worried, however, of being attacked by sharks. So, what are the chances of being attacked by one? In short: really, really slim. Popular Hollywood flicks like Jaws and its sequels, as […]
This is quite possibly the woolliest sheep in history, Shrek the sheep. He was found in this condition in 2004, in the very land of sheep – New Zealand – after escaping the annual spring shedding for six consecutive years. If you ever wondered what a really woolly sheep might look like, here you have […]
An extremely challenging study published by a team of researchers from the Stanford School of Medicine claims that through some unknown mechanism mammals can bias the sex of their offspring in order to win the genetic lottery and produce extra grandchildren. The holy graal of modern evolutionary biology After analyzing 90 years of breeding records […]
Research on nematodes have always been convenient for scientists. For one, they grow and breed really fast, making them ideal for work pertaining to genetics. Some of them have amazing properties, like the planaria or “flatworm”, which some scientists believe it possesses the indefinite ability to regenerate its cells and thus practically never grow old. It […]
What if the world’s greatest unsolved heists were made by aviary burglars? Bear with me for a second. A bird is small enough to fit through cages and window cracks, it can fly in and out fast and on the sly, and if it ever gets caught, it won’t turn its partners in crime since […]
It’s a dog eat dog out there, and any advantage you can get is more than welcome – as strange as it may be. According to a research published in Biology Letters on 3 July, Hawk moths create an ultrasonic noise that could be used to scare off an attacking bat and to jam the […]
In the aftermath of heavy rains from Tropical Storms Debby and Andrea, a giant mosquito species has surfaced and invaded central Florida. Authorities have issued warnings to residents to be extra careful of these very aggressive bloodsuckers that can grow up to 20 times the size of a typical mosquito. Their bite isn’t a lot more […]
A new visualization technique developed by researchers at the Howard Hughes Medical Institute used a thin sheet of laser light that beams, stepwise, into different planes of a specimen to create intricate and detailed snapshots of cells. In these pictures featured above and below you can see how zebrafish and fruit fly embryos were imaged using this novel […]
Living fossils, fast adapters Sturgeons have been conserved as fossils ever since the early Cretaceous – some 130 million years ago; they are what we call ‘living fossils’. But a new study by University of Michigan researchers revealed that in some aspects, sturgeons are one of the fastest-evolving fish on the planet. “Sturgeon are thought […]
At 55 million years old, it represents the earliest known member of this broad group of animals that includes humans. It may be no bigger than a mouse, but it is a primate, and a very valuable one at that; paleontologists have named it Archicebus, which roughly translates as “ancient monkey”. The team which described […]
Benjamin Wegener, a researcher at Monash University’s School of Biological Sciences and his team has shown that for squids, it’s really a dog eat dog out there: certain females consume male ejaculate and sperm as if they were foods, providing more energy for both themselves and future eggs. For females, it’s really a big win […]
Eggs, drugs and human lives For the standards of the criminals who poach and smuggle animals in Central America, it was just another day. But for the rest of the world, the murder of conservationist Jairo Mora Sandoval is a tragedy – a tragedy highlighting the risks faced by biologists whose passion for nature puts […]
The reemergence of the critically endangered population of Huemul deer (Hippocamelus bisulcus) marks a fantastic achievement by local governments and conservationists worldwide. Brought back from the brink of extinction, when populations measured less than 1% of original numbers, the Huemul populations have not only stabilized – but have started increasing, according to a new study. […]
Tho global meat giants with shady food and environmental safety records shook hands as they are planning to become the world’s biggest meat producer. Smithfield Foods, the largest pork producer in the U.S., has been bought by China’s Shuanghui International Holdings Limited for $4.7 billion. The global meat industry, which is grasped firmly by a […]
Researchers have for the first time described an unique snail species that can only be found high on top Mount Kaputar in New South Wales, Australia. The snails exhibit an atypical coloring – fluorescent pink – and can grow as large as eight inches long, true giants by snail standards. Though Triboniophorus aff. graeffei […]
50 years ago, if you took a cod from European waters, you’d have to cut it to be able to cook it. Nowadays, cooks easily fit one fish in a frying pan, even with a few vegetables. As unimportant as this fact may seem,it is actually a good reflection of the huge drop in fish […]
Every living being is important, however in a transnational-based society everything has a price label on it, even humans. A recent study, for instance, has assessed the economic value of sharks, both alive and dead. The researchers involved in the study found that shark ecotourism currently generates more than US$314 million annually worldwide and is expected […]
The Brazilian rain forest is a home to a slew of birds of all shapes, sizes and coloring – some 1,700 species to be more precise. One of such bird is the goofy looking toucan, which can be easily recognized by its extremely long beak which can reach half the size of the bird’s body. Human […]
Turtles are maybe the most majestic creatures in the reptile world, and have always been a source of inspiration for man. Everybody knows the fable of the turtle and the hare, which teaches how slow, but sturdy and resilient strides can outwit inconsistent sprints. The turtle’s really serious about it, and as evidence it practices […]
Researchers in Japan made good use of a new, state-of-the-art micro sculpting technique to create objects so small that they are the size of a single bacteria. One of these objects is the smallest bunny in the world, only a few micrometers wide, but the researchers have also demonstrated other shapes as well. Their work has […]
