Fish

Pardon me: Did a robot just hear fish farts?

A torpedo-shaped robot that bobbed up and down along the Florida coast to map sound production by red grouper and toadfish has detected what appears to be the unmistakable sound of herring passing gas.

That is, a robot heard what scientists believe to be fish farts.

Robotic jellyfish may never run out of energy

A robot built to look and swim like an inconspicuous jellyfish may keep going and going and going thanks to an infinite source of fuel — its surroundings.

The power comes from heat-producing chemical reactions between oxygen and hydrogen with platinum coated on the surface of the bio-inspired robot, known as Robojelly.

Real fish follow a robotic one

When we start to follow human-like robots wherever they choose to lead us, we’ll know the apocalypse has arrived. For fish, that moment is now.

Researchers have built a robot that sort of looks and swims like a fish and used it to lure real fish into schooling around it.

Robotic jellyfish gets more realistic

A robot designed to look and swim like a jellyfish has gotten even more realistic, according to a researcher working on the motion component of the machine.

The robot, known as Robojelly, was developed for the Office of Naval Research in 2009 to spy on ships and submarines, detect chemical spills, and monitor the whereabouts of migrating fish.

They did this by putting little wires, called bio-inspired shape memory alloy composites, that, when heated, contract just as a muscle does.

Oldest Antarctic Whale Found, Shows Fast Evolution

The oldest known whale to ply the Antarctic has been found, scientists say.

A 24-inch-long (60-centimeter-long) jawbone was recently discovered amid a rich deposit of fossils on the Antarctic Peninsula.

The creature, which may have reached lengths of up to 20 feet (6 meters), had a mouthful of teeth and likely feasted on giant penguins, sharks, and big bony fish, whose remains were also discovered with the jawbone.

New Shark Species Found in Food Market

It’s unlikely anyone’s ever complained, “Waiter, there’s a new species in my soup.” But the situation isn’t as rare as you might think.

A monkey, a lizard, and an “extinct” bird have all been discovered en route to the dinner plate, and now a new shark species joins their ranks, scientists report.

Fish taxonomists found the previously unknown shark at a market in Taiwan—no big surprise, according to study co-author William White.

Food Waste + Fish Poop = Lettuce

If, in a few years, you are suddenly overcome with a sense that there’s something fishy about the lettuce in your salad, you might be on to something. There’s a chance it was grown with fish poop.

“There’s no fish taste whatsoever,” Michael Amadori, a master’s student in ecological engineering at the State University of New York’s College of Environmental Science and Forestry, assured me Wednesday.

For now, Amadori is growing the futuristic lettuce in question as part of a science experiment aimed at closing the loop between the food we throw away and the food we eat.
