Atelopus varius
|
view preview
This is the Costa Rican variable harlequin toad ( Atelopus varius), also known as the clown frog (in spite of the fact that it is a true toad). They once ranged from Costa Rica to Panama, but are now listed as critically endangered and reduced to a single population in Costa Rica.

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.

The flightless bird from New Zealand
|
view preview
The kakapo is a strange little flightless bird native to New Zealand. Sadly there are now only 126 kakapo left in conservation areas, where they eat a range of plants. But researchers who have been studying ancient poo samples have recently found that around 900 years ago kakapo ate a lot of pollen from a root parasite known as Hades flower. The two no longer exist in the same place and Hades flower is also rare, which begs the question - were the birds responsible for pollinating it? Further research needs to be done, but it is an interesting conservation link. ...

Tractor beam
|
view preview
Scientists at University of St Andrews in Scotland and the Institute of Scientific Instruments (ISI) in the Czech Republic have designed a minute but completely functional tractor beam. Reminiscent of Star Trek, they use a beam of light to draw objects towards the light source on a microscopic level.

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. ...

True human tail (vestigial tail)
|
view preview
Only about 100 cases are documented around the world. The true human tail upon birth is caused by a lack of cell destruction of the distal end of the embryonic tail. According to some experts, the true human tail is not really a tail at all. It is thought to be linked to spina bifida or a hiccup in the natural human development process. While others thing that it is due to mutation of the genes that produce cellular destruction of the tail component As it is well known that it is derived from the most distal remnant of the embryonic tail. It contains adipose and connective tissue, central bundles of striated muscle, blood vessels, and nerves and is covered by skin while it lacks Bone, cartilage, notochord, and spinal cord. The true tail aris ...

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 ...
