Bees latch on to similarly-sized nectarless flowers to unpick pollen - like keys fitting into locks, according to a new study by researchers at the University of Stirling.
The research shows the right size of bee is needed to properly pollinate a flower. The bee fits tightly with the flower's anthers, to vibrate and release the pollen sealed within.
"We found that a pollinator's size, ... Read more »

Meet the Moroccan flic-flac spider (Cebrennus rechenbergi), a truly unique spider that when provoked or threatened escapes by doubling its normal walking speed using forward or backward flips similar to acrobatic flic-flac movements used by gymnasts.
C. rechenbergi is a species of huntsman spider indigenous to Morocco and can be found in the sand dunes of the Erg Chebbi desert . The spider ... Read more »

In a recent study, researchers provide a new theory for the reason we walk the Earth
A new provocative study suggests it was the power of the eyes and not the limbs that first led our ancient aquatic ancestors to make the momentous leap from water to land. According to it, crocodile-like animals first saw easy meals on land and consequently evolved limbs that enabled them to get there, ... Read more »

Deep sea creatures come with all kinds of strange features that help them to survive their cold, dark habitat.. Some have eyes the size of a basketball, others come with appendages that blink and glow, deep-sea dwellers have developed some strange features and the "cockeyed" squid Histioteuthis heteropsis has one normal eye and one giant, bulging, yellow eye.

Researchers recently announced the discovery of a frog whose groin flashes orange to scare away predators! The species was discovered in Australia.
When biologist Simon Clulow spotted a frog with an unusual marble pattern on its belly, he knew it could be a new species. If that turned to be true, it would be very surprising as the sighting took place on land close to an airport and not some ... Read more »

New research by NOAA Fisheries* has revealed the opah (Lampris Guttatus) to be the first fully warm-blooded fish. Also known as moonfish, it circulates heated blood throughout its body much like mammals and birds do, giving it a competitive advantage in the cold ocean depths.

To us humans, it seems extremely unnatural that other animals can reproduce without having sex. Yet with the passing of time, evolution has endowed females of several species of amphibians, insects, reptiles and fish the ability to asexually produce offsprings without "help" from males.
Now, researchers at the Okinawa Institute of Science and Technology Graduate University (OIST) say that in ... Read more »

There are about 200 species of caecilians (pronounced ‘seh-SILL-yuns’) but it's highly unlikely you have or will ever encounter one. Why? Because they live underground, burrowing through loose soil and ground litter with their long, snake-like bodies.
Read on to learn 9 weird and interesting facts about these unusual creatures.

Penis, the primary sexual organ that male and hermaphrodite animals use to inseminate sexually receptive mates (usually females and hermaphrodites respectively) during sex. Almost all species use some variation of the organ to transfer sperm into females' eggs in order to create more offsprings.
