This photograph of a great white shark following a kayak is probably one of the most iconic and popular shark images of all time. Every time it pops up, it unsurprisingly garners a lot of accusations of being fake, or edited.

We asks ourselves this a lot, so do stem cells!

This question has puzzled scientists for a long time.

Scientists think that they have the answer to why the skin on human fingers and toes shrivels up like an old prune when we soak in the bath. Laboratory tests confirmed a theory that wrinkly fingers improve our grip on wet or submerged objects, working to channel away the water like the rain treads in car tyres.

People often assume that wrinkling is the result of water passing into the outer layer of the skin and making it swell up. But researchers have known since the 1930s that the effect does not occur when there is nerve damage in the fingers. This points to the change being an involuntary reaction by the body's autonomic nervous system — the system that also controls breathing, heart ...

This is the pink-necked green pigeon (Treron vernans) and it is honestly not Photoshopped. They\'re found in Cambodia, Indonesia, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, and subtropical or tropical moist montane forests.

Octopus reproduction is fairly uniform across species. When a female is ready to mate, she releases a chemical into the water that attracts males. They follow this chemical to the female, where they will often fight one another for the right to mate with the female. Sometimes the female will mate with more than one male. The same chemical that attracts the males stops the males from eating the female - cannibalism is common amongst octopodes.

Once it has been decided who will be mating, the male transfers packages of sperm called \"spermatophores\" to the female using his third right arm (which typically has no suckers). The female stores these, and then builds a den. She then seals the entrance. Once this is complete, she lays the eggs and ...

Meet the goliath frog! This beast is the largest extant anuran on Earth.


They can grow up to 33 cm (13 inches) from snout to vent, and can weigh up to 3.2 kg. They have a fairly small habitat range, mainly in Cameroon and Equatorial Guinea and sadly their numbers are dwindling due to habitat destruction. They are also hunted for both consumption and for the pet trade.
