Viewers of the various “extreme angling” TV shows have likely already heard that it’s getting more and more difficult to find big fish in the world’s lakes and rivers. A new international study, however, now confirms that there has recently b… Continue reading Study reveals 88-percent decline in freshwater megafauna populations
Fans of a still-surviving megalodon, rejoice – a new species of deep-ocean shark has been identified. At just 5.5 inches long (about 144 mm), however, the American Pocket Shark is a bit smaller than the prehistoric super-predator…

An intriguing new study is offering insights into the origins of sleep, for the first time discovering zebrafish brains shift through several brain states while sleeping. The researchers suggest these states could be analogous to human slow-w… Continue reading Complex neural patterns discovered in fish sleep, shedding light on origins of slumber
An impressive new study, led by scientists from the Boston Children’s Hospital, has developed a novel method to tame one of the world’s most potent toxins, tetrodotoxin, commonly found in the pufferfish. The research demonstrates a way to con… Continue reading How deadly pufferfish toxin led to a breakthrough long-lasting local anesthetic
Scientists found plastics in the guts of amphipods at Challenger Deep, some 10,890 meters below the sea surface. Continue reading Microplastics Have Been Found in Our Deepest Ocean Animals
We love a little outside-the-box thinking around here, and anytime we see robots that don’t use wheels and motors to do the moving, we take notice. So when a project touting robotic fish using soft-actuator fins crossed the tip line, we had to take a look.
It turns out that this robofish comes from the fertile mind of [Carl Bugeja], whose PCB motors and flexible actuators have been covered here before. The basic concept of these fish fins is derived from the latter project, which uses coils printed onto both sides of a flexible Kapton substrate. Positioned near a magnet, …read more

Biologists just blessed the internet with this incredible video. Continue reading Utah Annually Bombs Its Lakes With Baby Fish Dropped From a Plane
We get it. You love your fish, but they can’t bark or gently nip at your shin flesh to let you know they’re hungry. (And they always kind of look hungry, don’t they?) One day bleeds into the next, and you find yourself wondering if you’ve fed them yet today. Or are you thinking of yesterday? Fish deserve better than that. Why not build them a smart fish feeder?
Domovoy is a completely open-source automatic fish feeder that lets you feed them on a schedule, over Bluetooth, or manually. This simple yet elegant design uses a small stepper motor to …read more

Here’s a Big Mouth Billy Bass with extra lip thanks to Alexa. If you’re not already familiar, Big Mouth Billy Bass is the shockingly popular singing animatronic fish designed to look like a trophy fish mounted to hang on your wall. In its stock condition, Billy uses a motion sensor to break into song whenever someone walks by. It’s limited to a few songs, unless you like to hack things — in which case it’s a bunch of usable parts wrapped in a humorous fish! Hackaday’s own [Bob Baddeley] combined the fish with an Amazon Echo Dot, connecting the two …read more
