Wake up and smell the reef: Fish larvae sniff their way back home
How tiny fish larvae travel away from the reef, then know how to navigate their way back home is a scientific mystery.
Global study reveals new hotspots of fish biodiversity
Teeming with millions of species, tropical coral reefs have been long thought to be the areas of greatest biodiversity for fishes and other marine life—and thus most deserving of resources for conservation.
Climate change could stop fish finding their friends
Like humans, fish prefer to group with individuals with whom they are familiar, rather than strangers. This gives numerous benefits including higher growth and survival rates, greater defence against predators ...
Boat noise stops fish finding home
