Rafflesia is a genus of parasitic flowering plants. He was found in the rainforests of Indonesia by an Indonesian guide working for Dr.. Joseph Arnold in 1818, and named after Thomas Stamford Raffles, the leader of the expedition. It consists of approximately 27 species (including four that have not fully known characteristics as recognized by Meijer 1997), all species found in Southeast Asia, the Malay Peninsula, Borneo, Sumatra, and the Philippines. This plant has no stems, leaves or true roots. Rafflesia is a endoparasit on Tetrastigma vines of the genus (family Vitaceae), spreading haustoriumnya similar roots in the network of vines. The only part of Rafflesia plant that can be seen outside its host plant is the flower crowned five. In some species, such as Rafflesia arnoldii, diameter of flowers may be more than 100 cm, and weighs up to 10 kg. Even the smallest species, Rafflesia manillana, flower diameter 20 cm. The flowers look and smell like rotting flesh, that's why he called the "corpse flower" or "meat flower". An unpleasant smell flowers attract insects such as flies and dung beetles, which carry pollen from male flowers to female flowers. Little is known about the spread of seeds. However, squirrels and other forest mammals eat the fruit and distribute it turns out the seeds. Rafflesia is the official state flower of Indonesia, as well as the province of Surat Thani, Thailand.
The name "corpse flower" which is used to Rafflesia is confusing because common names are also used to refer to the Amorphophallus titanum (suweg giant / trunk krebuit) from the family Araceae. Moreover, because Amorphophallus has the largest branched inflorescence in the world did not, he is sometimes mistakenly regarded as the world's largest flower. Both Rafflesia and Amorphophallus are flowering plants, but their kinship distance. Arnoldii Rafflesia has the world's largest single flower of all flowering plants, at least when people judge by their weight. Amorphophallus titanum has the largest branched inflorescence not while palm Talipot (Corypha umbraculifera) has the largest branched inflorescence, consisting of thousands of flowers; monokarpik this plant, which means that each individual die after flowering.

In the Pacific, a tiny island 300 miles away from the shore hides a giant mountain beneath the waves that forms a home for thousands of planton feeding fish. These fish attract tuna, and the tuna attract thousands of sharks. Watch this video to learn more about this fascinating food chain, and hear some weird but true facts about the visiting Hamerhead sharks. Brilliant short from BBC wildlife show Blue Planet.

As brine from the sea ice sinks, a 'brinicle' forms threatening life on the sea floor with a frosty fate.
A bizarre underwater "icicle of death" has been filmed by a BBC crew.
With timelapse cameras, specialists recorded salt water being excluded from the sea ice and sinking.
The temperature of this sinking brine, which was well below 0C, caused the water to freeze in an icy sheath around it.
Where the so-called "brinicle" met the sea bed, a web of ice formed that froze everything it touched, including sea urchins and starfish.
The unusual phenomenon was filmed for the first time by cameramen Hugh Miller and Doug Anderson for the BBC One series Frozen Planet.
Creeping ice
The icy phenomenon is caused by cold, sinking brine, which is more dense than the rest of the sea water. It forms a brinicle as it contacts warmer water below the surface.
Mr Miller set up the rig of timelapse equipment to capture the growing brinicle under the ice at Little Razorback Island, near Antarctica's Ross Archipelago.
"When we were exploring around that island we came across an area where there had been three or four [brinicles] previously and there was one actually happening," Mr Miller told BBC Nature.
The diving specialists noted the temperature and returned to the area as soon as the same conditions were repeated.
"It was a bit of a race against time because no-one really knew how fast they formed," said Mr Miller.
"The one we'd seen a week before was getting longer in front of our eyes... the whole thing only took five, six hours."
Against the odds
The location - beneath the ice off the foothills of the volcano Mount Erebus, in water as cold as -2C - was not easy to access.
"That particular patch was difficult to get to. It was a long way from the hole and it was quite narrow at times between the sea bed and the ice," explained Mr Miller.
"I do remember it being a struggle... All the kit is very heavy because it has to sit on the sea bed and not move for long periods of time."
As well as the practicalities of setting up the equipment, the filmmakers had to contend with interference from the local wildlife.
The large weddell seals in the area had no problems barging past and breaking off brinicles as well as the filming equipment.
"The first time I did a timelapse at the spot a seal knocked it over," said Mr Miller.
But the team's efforts were eventually rewarded with the first ever footage of a brinicle forming.
HOW DOES A BRINICLE FORM?
Dr Mark Brandon
Polar oceanographer, The Open University
Freezing sea water doesn't make ice like the stuff you grow in your freezer. Instead of a solid dense lump, it is more like a seawater-soaked sponge with a tiny network of brine channels within it.
In winter, the air temperature above the sea ice can be below -20C, whereas the sea water is only about -1.9C. Heat flows from the warmer sea up to the very cold air, forming new ice from the bottom. The salt in this newly formed ice is concentrated and pushed into the brine channels. And because it is very cold and salty, it is denser than the water beneath.
The result is the brine sinks in a descending plume. But as this extremely cold brine leaves the sea ice, it freezes the relatively fresh seawater it comes in contact with. This forms a fragile tube of ice around the descending plume, which grows into what has been called a brinicle.
Brinicles are found in both the Arctic and the Antarctic, but it has to be relatively calm for them to grow as long as the ones the Frozen Planet team observed.

Killer Whale or Orca (Orcinus orca) is the largest species of the dolphin family. This species is found throughout the oceans, from cold regions such as the Arctic and Antarctica to the warm temperate region. Killer whales are top predators in the oceans, most populations eating fish, while other populations consuming marine mammals like sea lions, seals, walruses to large whales. even on 04 October 1997 in the United States off the coast of California were, a group of whale watchers who are in traveling on the island of Farallon has recorded a unique occurrence of killer whales attacking adult white shark and then ate the shark. statement saying that the Sharks are predators that control the top spot in the ocean food chain was broken because of the events itu.paus killer live in groups they often hunt bersama.IUCN determine the conservation status of killer whales is not known, since several different killer whale populations jenis.Beberapa already threatened local habitat loss, pollution, marine mammal captured for the park, and conflicts with fishermen[endtext]

Chameleon or londok (Sundanese) is a kind of reptile belonging to the tribe (familia) Agamidae. Another lizard tribe are still flying lizard (Draco spp.) And soa-soa (Hydrosaurus spp.).
Chameleon includes several genera, such as Bronchocela, Calotes, Gonocephalus, Pseudocalotes and others. Chameleon can change its skin color change, although not as good as discoloration chamaeleon (tribe Chamaeleonidae). Usually change from bright colors (green, yellow, or light gray) becomes a darker color, brownish or blackish.
