1. The shore seems to be the edge of the continent, but that's not true: the continents continue under the sea, on a strip edging each continent, and called continental shelf. How much of the continental shelf is covered by the sea depends on how much ice is stocked in the Polar Ice. 2. Around 10,000 years ago, ... |

Corals really give a meaning to the notion that beauty is under the surface. That's the clearest seawater, a crystal clearness increased by the white sand. A coral reef is like a sea rainforest. Corals are colonies of polyps, small animals with a maximum diameter of 2.5 cm (1 in). The soft polyp is connected to... |

That's the clearest seawater, a crystal clearness increased by the white sand. A coral reef is like a sea rainforest. Corals are colonies made up of polyps, small animals with a maximum diameter of 2.5 cm (1 in). The soft polyp is linked to its neighbor through living tissue covered by mucus. During the day, the... |

You may be turned on by the image of Scarlet Johanson naked, but others have much weirder fantasies. The light of the silvery moon induces such an arousal amongst corals that soon the sea water gets flooded by coral eggs and sperms that turn the water milky. Those pervert astronomers...The connection between the moon... |

They have not created a 3-headed dragon yet, but by now scientists have managed to make a jellyfish with a dozen heads by carefully monkeying with a few genes. This experiment could explain how natural colonies of other multi-headed organisms first emerged, like that of the reef building corals. Researchers focused o... |

You can be naughty and get cold sores around your mouth or other orifices of your body. But for corals, this is not just annoying, it is killing them. Herpes viruses and other diseases could be a main factor in the deaths of coral reefs caused by humans throughout the world, as a new research reveals. It is well know... |

Coral reefs are limestone accumulations, which represent the skeleton of the corals, being found in the warm waters of the oceans. The reefs are for the sea like rainforest on the ground: they harbor the highest marine biodiversity, thus the highest number of fish species: thousands of species in the worldwide reefs.... |

The first nation victim of the global warming seems to be a micro-country in the middle of the tropical Pacific, made of 9 atoll islands and inhabited by 11,000 people: Tuvalu. "In geological time, all the atolls are condemned to disappear. But the climate change can accelerate this" said the French climatologist He... |

A coral is a colony made of small animals, called polyps. The polyps live in symbiosis with algae called zooxanthellae, that make photosynthesis, that's why the corals live only in lighted places. The photosynthesis products of the algae are eaten by the polyps and their waste products are used by the algae to s... |

Corals may be simple little sea creatures that form magnificent reefs in the tropical waters, but scientists were shocked to discover more genes in them than in humans! ... Moreover, even if they are at the base of animal evolution, corals share with people a lot of the immune system genes, and as corals are much ol... |
