(Viktor Nunes Peinemann via SWNS) By Dean Murray via SWNS Researchers have discovered a new species of fish so "perpetually displeased" they have named it the "grumpy dwarfgoby." A team at the University of Washington and King Abdullah University of Science (KAUST) spotted the fish in Red Sea coral reefs.

Despite its small size of less than two centimeters, the grumpy dwarfgoby is described as having surprisingly menacing appearance. Lucía Pombo-Ayora, who gave the species its common name and dubbed it a 'tiny horror', said: "I imagine in its own tiny world, it is a fearsome predator. Its grumpy expression and large canines certainly make it look the part, despite its small size.

There, it lives in small holes and crevices, using its large canines to capture tiny invertebrates.

A release explains: "The grumpy dwarfgoby appears to be a relatively rare species, which is likely why it remained undiscovered until now." The researchers found the first specimens in the Farasan Banks in Saudi Arabia, with additional specimens later found near Thuwal in the Red Sea.
