For the first time in 28 years, Alaska has a new butterfly: a possible hybrid between two related species that adapted to the harsh Arctic climate.
A new monitor lizard, scientifically known as Varanus semotus, was recently found isolated on Mussau Island. Boasting a long turquoise-spotted tail, this lizard is considered the island's top predator.
A new fossil fish found among a collection displayed at Perot Museum of Nature and Science in Dallas, Texas, boasted some interesting characteristics, including a rotund tuna-like body and "hook-shaped sail" on its back.
An extinct kangaroo ancestor wasn't able to bounce like its modern relatives, but they were able to easily adapt to environmental change and out-live their fanged cousins. Fossils of these creatures were recently unearthed in Australia by researchers from the University of Queensland.
Eight new whip spiders have been found in Brazil's Amazon rainforest. The arachnids resemble a cross between a spider and a tailless scorpion. This discovery nearly doubles the number known to inhabit Brazil, which now totals 25.
Rare fossils recently found in Idaho represent at least three new small to mid-sized species of theropod, which is the group of carnivorous dinosaurs that includes the Tyrannosaurus rex.
A new beetle species from Central America has been found with a never-berfore-seen heart-shapped leg joint. Since only males have been found, researchers have yet to determine what exactly the peculiar joint is used for.
For years, desert tortoise populations in Mexico remained grouped under two species. However, a new study has identified a third individual among the bunch.
Australian researchers recently found two new, remarkably large bent-toed geckos in New Guinea. Among the individuals is the largest species known to date, which has a name that translates to "king."
Scientists say the Red Sea is home to a a newly discovered luminous creature that lives on the shells of nocturnal snails.
Researchers have found and identified for new species of algae in Hawaii. However, the specimens were found at unexpected depths and closely resemble those found in much shallower waters.
Researchers recently unearthed two new plankton-eating fossil fish species, of the genus called Rhinconichthys. This discovery triples the number of known species.
Pink deep-sea worms previously represented by only a single species have puzzled biologists for nearly six decades. However, four new worms recently spotted near California and Mexico have helped scientists properly place the creatures along the evolutionary tree of life.
Over a decade's worth of research has revealed 14 new tarantulas in U.S., which is now home to a total of 29 species. One of the new spiders found in California was named after the late popular singer-songwriter Johnny Cash.
