Proboscis monkey nose
|
view preview
Meet the proboscis monkey ( Nasalis larvatus), a monkey only found in Borneo Island, Asia. The proboscis monkey is one of the largest monkeys native to Asia. It's very easily identified (for obvious reasons). The species has very pronounced sexual dimorphism, with the male being much larger than the female. Males also have much larger noses (the individual pictured is a male), but the noses of females are still very pronounced. The bigger the nose a male proboscis monkey has, the bulkier he will be — increasing his chances of attracting a large harem. Both sexes have bulging stomachs that give them the impression of having a pot belly. The proboscis monkey is assessed as Endangered in the IUCN Red List of Threatened Species and listed in Appen ...

Yellow Pages -- a waste of resources
|
view preview
The Yellow Pages use no virgin paper in the production of their directories, but to produce and deliver 540 million a year requires immense amounts of water and uses immense amounts of energy and fuel. If you need the Yellow Pages, keep it! But if you are among the 70% polled who say they never even open them, opt out. It is just a waste not to.

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 white shark kayak
|
view preview
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.

Regal ringneck snake
|
view preview
This is the regal ringneck snake ( Diadophis punctatus regalis), a subspecies of ringneck snake endemic to the southwestern United States and northern Mexico. Unlike other subspecies of ringneck snakes, the regal ringneck is almost exclusively ophiophagous, meaning that it has a diet that consists almost entirely of other snakes. They have a weak venom that serves to immobilize their small prey, but is harmless to humans.

Underwater world
|
view preview
Near the town of Tragöß in Styria, Austria you can find this stunning lake known as Grüner See (Green Lake). Named Green Lake for its amazingly clear emerald green water it’s mostly the result of seasonal snowmelt from the surrounding Hochschwab Mountains and forests. During winter months the lake is only 1-2m deep with the rest of the area used as a county park, however as spring arrives the lake grows in size from all the melting snow reaching at its peak around mid-May 12m deep in places. Not surprisingly the waters are a little chilly at 6-7oC, although it remains popular among divers during the peak months who love to pose on the underwater bench and visit the flooded green meadows. ...

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 ...
