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. ...

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 ...

Do fish ever get thirsty?
|
view preview
A student in my class once asked, do fish ever get thirsty? I was 15 at the time, and I remember my science teacher struggling to answer the question. Here's the best possible answer I can give you -- it all depends whether the fish is a saltwater fish or a freshwater fish. Click the image for more details Notice how the fresh water fish actually obtains H 2O via the food it consumes, not through drinking. Whereas the saltwater fish actually drinks the water can hence has highly concentrated urine. ...

The science of fireworks
|
view preview
Many of us around the world will enjoy a firework display tonight (or have already); but what are the mechanisms behind the magnificent spectacle?The story behind fireworks begins about 2000 years ago in China. Alchemists at the time were in search for an elixir which made them immortal. Obviously, they did not find this- what they did find however was a substance consisting of potassium nitrate, charcoal and suphur; or gunpowder,as we know it. The evolution of fireworks from gunpowder took another 1000 years until a monk named Li Tian realised that if you placed gunpowder into a bamboo tube and ignited it, an impressive explosion on sound and light ensued. Fireworks were born! The gunpowder is responsible for the trajectory of the firework, ...
