Fish have a sensory system known as the lateral line, which allows them to detect movements, vibrations and pressure gradients in the water. Scientists have now given a robotic fish its own version of that system, letting it determine the best swimming… Continue reading Robotic fish learns to match its swimming speed to the current
The whale shark and the manta ray are perhaps two of the ocean’s most fascinating large fishes. Well, scientists have now announced the discovery of a prehistoric ancestor of both, that looked like a cross between the two.Continue ReadingCategory: Biol… Continue reading Prehistoric “eagle shark” combined traits of sharks and rays
For the past 150 years or so, scientists have theorized that the life cycle of the present-day lamprey mirrors the evolution of all fish – and thus of all vertebrates. Newly analyzed fossils, however, indicate that such is not the case.Continue Reading… Continue reading Fossil analysis reveals that lampreys are not “swimming time capsules”
It’s very important for fish farmers to keep track of the number of fish in their pens, but doing so typically involves going in and actually netting out some of the fish. According to new research, echo-sounding tech could soon serve as an easier and … Continue reading Echo-sounding used to count farmed fish – without all the hassle
Some animals sustain grave injuries and may struggle to return to full health, while others, such as newts and salamanders, possess a remarkable ability to regenerate damaged tissues. Whale sharks may have more in common with this latter group than pre… Continue reading Whale sharks observed regrowing damaged dorsal fins for the first time
Genome sequencing can teach us a huge amount about a species, and now scientists have completed the sequence for one of the weirdest and most intriguing animals in the world. The Australian lungfish is a “living fossil” from the time our ancestors firs… Continue reading “Living fossil” genome sequence reveals clues to evolution of life on land
Robotics has advanced in leaps and bounds over the past few decades, but in terms of decentralized coordination in robot swarms, they far behind biological swarms. Researchers from Harvard University’s Weiss Institute are working to close the gap, and have …read more

It has generally been thought that electric eels are purely solitary animals, which stalk prey on their own. Now, however, scientists have described seeing the creatures hunting in packs – which only nine other fish species are known to do.Continue Rea… Continue reading Not-so-solitary electric eels observed hunting in packs
Back in 2014, we heard about a so-called “fish gun” or “salmon cannon” that safely shot spawning fish up over river-blocking obstacles such as dams. Its successor is now in use, offering a couple of key advantages over the original system.Continue Read… Continue reading “Salmon cannon” successor automatically shoots fish up over dams
Dams pose a great obstacle to fish migrating up rivers, potentially keeping them from breeding, thus leading to a decline in wild stocks. Australian scientists are on the case, though, with a possible solution known as the “tube fishway.”Continue Readi… Continue reading “Tube fishways” could safely lift fish up and over dams
