How fish evolved their bony, scaly armor
About 350 million years ago, your evolutionary ancestors—and the ancestors of all modern vertebrates—were merely soft-bodied animals living in the oceans. In order to survive and evolve to become what we are today, these animals needed to gain so.....»»
Earliest fish-trapping facility in Central America discovered in Maya lowlands
An archaeologist from the University of New Hampshire and her team have collected data which indicates the presence of a large-scale pre-Columbian fish-trapping facility. Discovered in the Crooked Tree Wildlife Sanctuary (CTWS), the largest inland we.....»»
Ancient fish-trapping network supported the rise of Maya civilization
The Maya were landscape engineers on a grand scale, even when it came to fishing. On the eve of the rise of the Maya civilization, people living in what’s now Belize turned a wh.....»»
How does the Regen Shield work in Valorant?
Patch 9.10 of Valorant introduced a new type of armor called Regen Shields. But how does it even work? We'll explain what this armor does and if it's worth it......»»
"Doomsday fish" washed ashore in California, but what does that mean?
If one oarfish landing on a beach is a sign of a disaster to come, how bad will it be if three wash up in quick succession?.....»»
Fewer than 7% of global hotspots for whale-ship collisions have protection measures in place, researchers report
According to the fossil record, cetaceans—whales, dolphins and their relatives—evolved from four-legged land mammals that returned to the oceans beginning some 50 million years ago. Today, their descendants are threatened by a different land-base.....»»
Enhancing visibility for better security in multi-cloud and hybrid environments
In this Help Net Security interview, Brooke Motta, CEO of RAD Security, talks about how cloud-specific threats have evolved and what companies should be watching out for. She discusses the growing complexity of cloud environments and the importance o.....»»
Reef studies highlight missing clues to conserve fish species
In Australia, shellfish reef restoration projects are helping to recover degraded coastal systems and enhance fish habitat, but much more research is needed to support and evaluate these efforts, researchers say......»»
Superior photosynthesis abilities of some plants could hold key to climate-resilient crops
More than 3 billion years ago, on an Earth entirely covered with water, photosynthesis first evolved in ancient bacteria. In the following millions of years, those bacteria evolved into plants, optimizing themselves along the way for various environm.....»»
Invasive zebra mussels are associated with elevated mercury levels in fish, study finds
A study found that invasive zebra mussels significantly alter aquatic ecosystems, and are associated with elevated mercury concentrations in fish. Mercury, a potent neurotoxin, poses a serious threat to both aquatic life and human health......»»
Scientists discover the molecular composition of potentially deadly venomous fish
New research in FEBS Open Bio reveals insights into the venom of two of the most venomous fish species on Earth: the estuarine stonefish (Synanceia horrida) and the reef stonefish (Synanceia verrucosa), which are typically found in the warm and shall.....»»
How humans evolved to be "energetically unique"
Humans, it turns out, possess much higher metabolic rates than other mammals, including our close relatives, apes and chimpanzees, finds a Harvard study. Having both high resting and active metabolism, researchers say, enabled our hunter-gatherer anc.....»»
First ever goat-fish petroglyph reveals Egyptian understanding of zodiac symbols
A new study by Dr. Linda Evans and her colleagues from Macquarie University, Australia, published in the Journal of Egyptian Archaeology, has recently identified what may be an Egyptian petroglyph depicting the zodiac sign Capricornus, a hybrid creat.....»»
Latest edition of book offers guidance on monitoring and managing ranaviruses in amphibians, reptiles and fish

The climate and biodiversity crises are entwined, but we risk pitting one against the other
Climate change and biodiversity policies have largely evolved in isolation, even though the two crises are deeply intertwined. They have their own UN summits, with the same name and numbering system: the UN biodiversity summit Cop16 just concluded in.....»»
Fish on film: Uncovering the environmental drivers of black spot syndrome
For many researchers in biology and other natural sciences, dissecting specimens may not be desirable, though it is often necessary. This is because dissection means killing the animal a researcher is trying to study—a big issue, especially if the.....»»
In collective animal movements, speed matters—scientists use "force map" to investigate fish schools
Few things are as fascinating to look at a flock of starlings performing their aerial bird dance that is commonly seen, for example, above the West Pier in Brighton, UK, or in Rome when exiting the main train station, or a school of fish escaping a p.....»»
Mathematical model can help understand coexistence in nature
Different species of seabirds can coexist on small, isolated islands despite eating the same kind of fish. A researcher at Uppsala University has been involved in developing a mathematical model that can be used to better understand how this ecosyste.....»»
Troubled waters: How to stop Australia"s freshwater fish species from going extinct
Three-quarters of Australia's freshwater fish species are found nowhere else on the planet. This makes us the sole custodians of remarkable creatures such as the ornate rainbowfish, the ancient Australian lungfish and the magnificently named longnose.....»»
Decline in West African coastal fish stocks threatens food security and livelihoods
Small-scale fisheries play a vital role in providing food and livelihoods for millions of people around the world, particularly in low-income countries in Africa. However, there is limited statistical data on the composition, abundance, and distribut.....»»
