Australian lizard scares away predators with ultra-violet tongue

When attacked, bluetongue skinks open their mouth suddenly and as wide as possible to reveal their conspicuously coloured tongues. This surprise action serves as their last line of defence to save themselves from becoming prey says Martin Whiting, of Macquarie University in Australia. The research revealed that the back of the northern bluetongue skink's tongue is much more UV-intense and luminous than the front, and that this section is only revealed in the final stages of an imminent attack, according to Science Daily.

Guppies change their eye color to deter rivals

Tiny fish called Trinidadian guppies turn their eyes black to warn other fish when they are feeling aggressive, new research shows.

A study, found that when facing a rival, guppies rapidly turn their irises from silver to black before attacking their adversary, according to Science Daily.

This makes their eyes more conspicuous and is an "honest" signal of aggression -- larger guppies do it to smaller ones whom they can beat in a fight, but smaller ones do not return the gesture.

Fungi that turn ants into ZOMBIES have adapted to climate change to manipulate infected hosts so they pick the best spot to spread their spores

A parasitic fungus that turns carpenter ants into ‘zombies’ is learning to adapt to the changing climate.

The fungus is known to infect carpenter ants and cause them to clamp onto hanging vegetation, where they dangle for months to spew spores, according to Daily Mail.

But, researchers have found that zombie ants don’t always bite onto the same part of the plant.

According to a new study, this is because the choice of leaves or twigs boils down to the local climate – and, as conditions continue to change, the fungi have been forced to adapt.

Land rising above the sea 2.4 billion years ago changed planet Earth

Chemical signatures in shale, the Earth's most common sedimentary rock, point to a rapid rise of land above the ocean 2.4 billion years ago that possibly triggered dramatic changes in climate and life, according to Science Daily.

In a study, researchers report that shale sampled from around the world contains archival quality evidence of almost imperceptible traces of rainwater that caused weathering of land from as old as 3.5 billion years ago.

Birds had to learn to fly all over again after the asteroid apocalypse that killed the dinosaurs 66 million years ago

Bird species had to learn to fly all over again, after the colossal asteroid that wiped out the dinosaurs some 66 million years ago also grounded all avian life.

That's the finding of new research that sheds new light on how bird species survived the devastating asteroid impact that ended the reign of the dinosaurs, according to Daily Mail.

Scientists believe the asteroid also triggered the destruction of forests across the globe. With their natural habitat destroyed, tree-dwelling bird species soon died out.

Only avian species that lived on the ground were able to survive the Cretaceous-Paleogene mass extinction, known as K-Pg.

Emerging from the ashes of the cataclysm were these larger species of land dwelling birds, equivalent to today's emus and ostriches.
