Can Parrot Brains Teach Us About Human Speech? Study Finds Budgies Have Language-Producing Regions That Resemble Our Own

The parakeets commonly kept as pets could offer fresh clues about vocal learning and potential treatments for speech disorders

"Mr. Blobby" is a blobfish discovered in 2003 off the coast of New Zealand. The preserved specimen is now housed at the Australian Museum in Sydney.

Voters Crown the ‘World’s Ugliest Animal’ as New Zealand’s Fish of the Year

The blobfish is specially adapted to life in the deep ocean, but it looks like a shapeless blob when brought to the surface. It beat out the other candidates with its “unconventional beauty”

The fish feasted on phantom midge larvae, insects and bivalves before they died.

Paleontologists Stumble Across 15-Million-Year-Old Fish Fossils That Are So Well Preserved, Their Last Meals Are Intact

Discovered in Australia, the fossils represent a new species that lived during the Miocene epoch and highlight how iron-rich rock can protect specimens over time

Iguanas Floated a Whopping 5,000 Miles From North America to Fiji on Rafts of Plants in a Record-Setting Trip, Study Suggests

Since most iguana species live in the Americas, biologists have long debated how they could have arrived on the remote Pacific island in the first place

When the motorist stopped to take a closer look at the kittens, one of them ran under his truck.

Discovered in the drainage area of a creek bed, the tusk was initially thought to be “just an old stump”

Before taking samples, students carefully examined the environment.

Nine New Tardigrade Species Discovered Thanks to the Efforts of Danish Schoolchildren

The budding scientists collected the tiny water bears in a massive citizen science project that involved almost 30,000 participants

When they're alarmed, blue-lined octopuses display iridescent blue rings on their arms to ward off approaching predators.

These Male Octopuses Use Venom to Subdue Female Mates—and Avoid Being Eaten After Sex

Scientists observed male blue-lined octopuses injecting tetrodotoxin into females, which rendered them immobile for mating

A new study suggests that the lemon shark, pictured here, is a better analogue for the megalodon's size than a great white.

Megalodon Might Have Been Longer and Skinnier Than Previously Thought, Growing Up to 80 Feet

A new paper suggests the enormous, extinct shark looked less like a bulky great white and more like an elongated lemon shark

In one nest, researchers found a McDonald's McChicken container from 1996.

These Bird Nests Are Full of Trash, Including Some That’s 30 Years Old

Scientists studying Eurasian coots in Amsterdam found layers of decades-old garbage in their urban nests

Ice calves off the Breidamerkurjokull, a glacier in Iceland. Some scientists suggest prehistoric glaciers hold the answers to how life evolved on Earth.

How Enormous Glaciers on the Frozen ‘Snowball Earth’ Might Have Bulldozed the Path to Complex Life on Our Planet

A new study suggests glaciers carved metals out from the Earth’s surface 700 million years ago, leading to chemical reactions in the oceans that set the stage for early animal evolution
