Hammerheads hold their breath to keep warm when deep-diving for food

Researchers at the University of Hawai’i at Mānoa have made a surprising first discovery: scalloped hammerhead sharks hold their breath like air-breathing marine mammals when they deep dive into cold waters to feed. The finding has improved our underst… Continue reading Hammerheads hold their breath to keep warm when deep-diving for food

Groundbreaking robotic fish has a twisted method of propulsion

When designing fish-like underwater robots, you want a means of propulsion which is both energy-efficient and reasonably speedy. A new tail-flapping system may fit the bill, paving the way for wider usage of such bots.Continue ReadingCategory: Robotics… Continue reading Groundbreaking robotic fish has a twisted method of propulsion

“World’s first” cultivated fish fillets served up in Israel

In the past two years, Israel’s Steakholder Foods (formerly MeaTech 3D) has brought us a lab-grown steak and lab-grown Wagyu beef morsels. Now, it has produced what it says are the world’s first whole fillets of cultivated fish … grouper, to be precise… Continue reading “World’s first” cultivated fish fillets served up in Israel

Scientists unlock the survival secret of water-squirting mother mussels

It would be an understatement to say that mussels and other mollusks usually aren’t thought of as being particularly active. Recently, however, scientists have documented a water-squirting behavior in just one species, which is apparently using the act… Continue reading Scientists unlock the survival secret of water-squirting mother mussels

World-first aquaculture operation will raise salmon and kelp together

Although salmon farms help take pressure off wild stocks, the penned fish do produce a lot of waste which is concentrated at one location. A new farm is exploring a solution to that problem, by raising salmon and kelp in adjacent pens.Continue ReadingC… Continue reading World-first aquaculture operation will raise salmon and kelp together

“Blue foods” can tackle global malnutrition, disease and climate change

A new study has shown that foods that come from the ocean or freshwater, known as “blue foods,” have the potential to address several important global issues, including nutritional deficits, disease, and climate change.Continue ReadingCategory: Health … Continue reading “Blue foods” can tackle global malnutrition, disease and climate change

Fish can recognize themselves in a photo, says new study

The myth that goldfish have only a three-second memory might be giving us an unfair view of their mental capabilities. A new study has shown that some fish can recognize themselves in a photograph, meaning they join a pretty exclusive club of animals k… Continue reading Fish can recognize themselves in a photo, says new study

World’s oldest vertebrate brain found in 319-million-year-old fossil

The fossilized skull of a fish, with a penny for scale, contains the oldest preserved brain of a vertebrate at 319 million years old

Most of what we know about ancient extinct animals comes from their bones, since soft tissues don’t usually fossilize well. But now, scientists have discovered the oldest preserved vertebrate brain, in a fossilized fish almost 320 million years old.
