New 'grumpy' fish species discovered in the Red Sea

Scientists have discovered a new species of fish, the 'grumpy dwarfgoby'. Found among coral reefs in the Red Sea, it has large canines and a fierce expression, even though it is only 2 cm long. Its existence highlights the region's rich biodiversity, but also stresses the need for conservation efforts as climate change causes major disturbances to the reef's ecosystem.
