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.

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. ...

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.
