Meet the goliath frog
|
view preview
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.

A rolling stone gathers no moss
|
view preview
This guy brings new meaning to the phrase “A rolling stone gathers no moss.” The Venezuela Pebble Toad is a strange creature. It is typically found in mountainous regions, with many slopes and inclines. The toad is only about the size of a fingertip. As such, it is vulnerable to attacks from even a spider, like a tarantula. The Pebble Toad has an ingenious defence mechanism. When faced with a danger, it tucks its limbs and head under its body and tenses its muscles. Forming a ball shape, it begins to roll down whatever slope it happens to be on. This allows it to evade whatever predator may be pursuing it. Since they are so tiny and their muscles are so rigid, they take no damage from the bouncing and rolling. The Pebble Toad was featured in t ...

Have you ever seen octopus eggs before?
|
view preview
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 ...

Could you break through this bulletproof glass?
|
view preview
Bulletproof glass manufacturer 3M Security Glass placed this advertisement at a bus stop. There's apparently $3 million in cash inside there, behind their bulletproof glass. If you can break it, it's yours. Here's how bulletproof glass works...At first glance, bullet-resistant glass looks identical to an ordinary pane of glass, but that's where the similarities end. An ordinary piece of glass shatters when struck by a single bullet. Bullet resistant glass is designed to withstand one or several rounds of bullets depending on the thickness of the glass and the weapon being fired at it. So, what gives bullet-resistant glass the ability to stop bullets? Different manufacturers make different variations of bullet-resistant glass, but it is basic ...

Why do we get wrinkly fingers and toes when we leave our digits in water for too long?
|
view preview
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 ...

Garden in a bottle
|
view preview
This miniature ecosystem has been thriving in an almost completely isolated state for more than forty years. It has been watered just once in that time. The original single spiderwort plant has grown and multiplied, putting out seedlings. As it has access to light, it continues to photosynthesize. The water builds up on the inside of the bottle and then rains back down on the plants in a miniature version of the water cycle. As leaves die, they fall off and rot at the bottom producing the carbon dioxide and nutrients required for more plants to grow. ...

The white shark kayak

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.

The goblin shark
|
view preview
This is the goblin shark, a bizarre and rarely spotted creature found in water deeper than 200 m throughout the world. Very little is known about their life history or reproduction, as encounters with them in their native habitat are incredibly rare. Most specimens are dragged up by deep sea fishers. They are famous for their strangely shaped heads - they have snouts much longer than any other shark, and retractable jaws.
