Oceans are running out of fish - much faster than we thought

The global fish stocks are depleting at alarming rates, much faster than reported by the UN, a study found.

How some fish use polarized light to make themselves invisible to predators

You'd think there's not much a little fish can do to hide from predators in open waters. But when rocks, algae and other marine nooks and crannies are nowhere to be found, fish turn to manipulate the physical interactions of light to balance the scale. For instance, some open ocean fish species employ specialized skin cells that reflect polarized light. This reflection is most effective, not coincidentally, at the 'chase angle' or from the predator's point of view. It's so effective that the US Navy is funding work that might shed light how exactly some fish do this and how this can be applied to make submersibles equally inconspicuous.

Scientists figure out where enamel came from

Enamel, the hard, mineralized substance that covers your teeth originated on tough fish scales and then migrated to the teeth, researchers found

Thousands of Fish To Be Freed From Abandoned Mall in Thailand [with Photos]

The Bangkok’s New World Mall is one of the most dystopian places on Earth – initially 11 stories high, now the building can only boast 4, and it has no roof. A population of fish thrived in the post-apocalyptic setting, but now, with the building being set for demolition, the fish are finally going to be […]

Ancient 420-million-year-old fossil hints of bony fish and cartilaginous fish common ancestor

Based on fossil evidence and genome analysis, scientists know that the two groups diverged from a common ancestor around 420 million years ago, but we've yet to find actual fossil of it. Things are shaping up though after paleontologists have identified an Early Devonian fish from Siberia, approximately 415 million years old, which bears features of both classes.

Ancient 385-million-year old Fish pioneered Sex

Paleontologists have identified the first known animals that used internal fertilization instead of spawning – armor-coated swimmers, called antiarchs, which lived around 385 million years ago in lakes in what is now Scotland. The discovery is truly monumental since its the earliest known example of sexual dimorphism or differences in appearance between the sexes in the […]

Not only do fish feel pain, but they also multi task and even have cultural traditions

Do you still think that fish don’t feel pain? That we shouldn’t really care how we catch or treat them? If so, then you’re terribly wrong. In a new article published in Springer’s journal Animal Cognition, Associate Professor Culum Brown from Macquarie University concludes that not only do fish feel pain and are conscious of it, but […]

Robot fish is remarkably similar to the real thing

Isaac Asimov, the father of the three laws of robotics, made some startling predictions many years ago about how thet future might look like. He’s been dead on in some respects, however the writer miscalculated how advanced robots would be in 2014 and how integrated these would become in human society. You see, before robots […]

New Arapaima species discovered in Amazon: a giant fish that can breath air

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 […]

Prehistoric fish had the earliest face recognized thus far

A lot of complex organisms, be them long extinct like dinosaurs or still alive like mammals, present what can only be referred to as a face – a symmetrical arrangement on the head of the animal of eyes, nose and, most importantly, jaw and cheek-bones. Human are particularly adapted to recognizing faces. Thanks to our […]

Faith in humanity restored: disabled pet fish that can't swim fitted with life jacket

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, […]

This fish likes to play rough: the male has four hooks on its genitalia

Biologists have found a new species of fresh water fish east-central Mexican waters, and what they discovered was more than they bargained for. Apparently, to fight off the female’s selective reproduction blocking mechanism, the male has evolved an… interesting, let’s say, penetration mechanism of its self – a four hook genitalia. No, this is not a […]

Seagrass on ocean coasts can store twice as much carbon as tropical rainforests, yet face destruction

A new research from a team of international marine geoscientists has found that seagrass meadows, found in coastal regions, can store up to twice as much carbon as temperate or tropical forests. The scientists involved in the study, thus, believe that seagrasses can potentially become a viable solution to climate change, if scaled and preserved […]

Ocean life threatened by mass extinction

Climate change and over-fishing are held responsible for the swift collapse of coral reefs and the propagation of mass extinction among marine life. According to the International Programme on the State of the Ocean (IPSO), which presented the study this Tuesday to the U.N., the Earth is faced with its biggest spate of mass extinctions […]

No, what you're seeing isn't a road

When I saw this picture, it was morning, my eyes hadn’t opened up quite yet, and I thought “what’s so special of a picture of a road?”. But then it hit me. It wasn’t a road. It’s a Louisiana waterway literally covered with dead fish, crabs, stingray, eel, and there have been reports of even […]

Photosynthesis - not just for plants anymore

As any fourth grader will tell you, photosynthesis is (in layman terms), the process through which plants (and bacteria, algae, etc) get the sugars and other organic compounds they need using energy from sunlight. However, during last week’s synthetic biology conference in Boston, a biologist from Harvard took things to a whole new level, presenting […]

Amazingly long fish filmed

Mark Benfield from Louisiana State University, Baton Rouge was undertaking a survey when he spotted this amazing oarfish at about 10 meters long. The fish is one of the longest in the world, and it’s general aspect resembles that of a serpent, so it’s possible it lies at the basis of some sea serpent myths. […]

9 amazing displays of fossil art

Art is a relative term, especially in these modern times. In its most accepted term, art is the deliberate process of arranging certain elements in such a way that appeals to the senses, trying to achieve beauty. But what these elements are and how they are arranged is up to the artist. So it shouldn’t […]

Fish that communicate by getting red

Most fish can’t even recognize the color red – let alone use it for some precise purpose. However, the exception here are some deep sea fish, yet Enneapterygius pusillus found a really interesting way of communicating. It literally glows in a deep red color, signaling different forms of intent. According to a study conducted in […]

Crawling, not swimming fish discovered

A University of Washington fish expert claims to have discovered a whole new species of fish, that would rather crawl into crevices than swim, and that may be able to see in the same way that humans do. Well this is certainly something unexpected, and there is no species that does the same kind of […]
