Scientists find some fish can ‘recognise themselves’ in mirror

They are often said to have a three-second memory, but the brain power of fish has been considerably underestimated, according to scientists who found some fish can recognise themselves in the mirror. Their findings suggest that a small, otherwise unremarkable species called the cleaner wrasse has joined an elite handful of others to have passed…

The superbug-fighting potential of fish slime

The growing threat of antibiotic-resistant bacteria is seeing scientists get more and more creative in their search for new drugs that might help us maintain the upper hand. Tobacco flowers, rattlesnake venom and Brazilian berries are just a few of the places to turn up exciting new antibiotic candidates of late, and now researchers have uncovered what they say is a potential…

Bleaching Severely Decreases Fish Diversity In Australian Coral Reefs

Australia’s Great Barrier Reef is the largest structure on Earth made by living things – tiny coral animals make up the nearly 3,000 reefs off the coast of northeastern Australia. These expansive reefs house what is possibly the most diverse assemblage of fishes (over 1,500 species) in the world. And, as climate change continues to intensify storm activity and increase…

Deep-sea fish can see colour in darkness, scientists say

 Some deep-sea fish may possess keen colour vision to thrive in the near total darkness of their extreme environment thanks to a unique genetic adaptation, scientists say. Researchers analysed the genomes of 101 fish species and found that three lineages of deep-sea fish, living up to about 1500 metres below the surface, boast a specialised…

Shipwrecks may help tropical fish adapt to climate change

When Chris Taylor presses play, footage of blue wrasse and greater amberjack fills the screen. The fish whirl and spin against a vivid backdrop of corals, sponges, and algae. When Taylor, an ecologist at NOAA’s National Centers for Coastal Ocean Science in Beaufort, North Carolina, asks visitors to the Centers where they think the video was taken, he’s not…

An international team of researchers discovered a previously unknown visual system that may allow color vision in deep, dark waters where animals were presumed to be colorblind. The research appears on the cover of the May 10, 2019, issue of the journal Science. “This is the first paper that examines a diverse set of fishes and…
