1.The first cetacean was Pakicetus, which lived 55 million years ago. It was a shore animal with well-developed four limbs. The first dolphins (and toothed whales) are considered the Squalodontidae, which lived 33 to 15 MA years ago. They were 3 m (10 ft) long and had large teeth. There are 32 dolphin species. The sm... |

The Black Sea is already considered one of the most polluted seas in the world. In the last 40 years it turned into a sort of depository for half of Europe, a place for depositing huge amounts of phosphorus compounds, mercury, DDT, oil and other toxic wastes coming from the 160 million people inhabiting its shores. T... |

Lizards can regrow a tail, octopuses their lost arms and some salamanders like axolotl even lost limbs. But sea cucumbers are the champions of organ regrowth: they can barf their whole gut out to escape predators and regrow it. Now a study made at the University of Puerto Rico connected their wound healing skills wit... |

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... |

Amongst many theories trying to explain the humans' physical appearance is that of the marine ape. But a new research reveals the oldest evidence of Homo sapiens living 164,000 years ago on the sea shore and feeding on sea food. Besides the so-called 'beach party', the new research shows a much more ad... |

1.Cetaceans (whales and dolphins) appeared 50 million years ago (the oldest known whale being Pakicetus), having (as revealed by DNA) a common origin with …the hippopotamus (!). 40 million years ago whales were divided into baleen whales and toothed whales. The oldest known baleen whale is Mamalodon (that lived 25 mi... |

We are looking for life in other worlds and we have not actually catalogued the entire life on Earth yet. And perhaps the most unexplored life on Earth is found in deep sea, for obvious reasons. A team of U.S. and Philippine scientists led by Dr. Larry Maddin of the Massachusetts-based Woods Hole Oceanographic Instit... |

The first cephalopods ("head-foot") appeared 500 million years ago. They were shelled, just like their relatives, snails and clams. But later, in Devonian, Carboniferous, Triassic, and Tertiary Epochs, with the evolution of the fish, marine reptiles, and later whales, to survive, the shelled cephalopods had to retrea... |

Perhaps most of the things that we know about sharks come from the movies and documentaries presenting the terrible great white shark and the reef sharks. What else?1.Generally, sharks are carnivorous, eating from sea urchins to mollusks (including squids and octopuses), sea mammals (seals, dolphins and whales), sea ... |

It may look like a 100-foot-long (33 m) noisy water spider coming from a science fiction movie but Proteus, a so-called Wave Adaptive Modular Vessel, is real and the latest in the navigation. It was developed for many purposes: from military uses to biological research, ocean exploration and sea rescue. "The lightwei... |

They may look like enormous sacks of blubber but one would not easily guess the performances the elephant seals are capable of. The southern elephant seal is the largest seal of all, with the largest males reaching up to 22.5 ft (6.9 m) long and 11,000 pounds (5,000 kg) in weight. Their name is due to their size and ... |

What's the similarity between your gut and the bottom of the ocean? Well, they're both dark and oxygen-poor places. And full of bacteria. Now, a group of Japanese researchers has discovered that some of the nastiest germs thriving in the human intestine, triggering some severe diseases could have evolved f... |

From a commodity one hundred years ago, today water has turned into a must. But in densely populated dry areas, the obvious solution is to get drinking water from the sea. People have been obsessed for millennia with finding a way to get rid of the sea salt for achieving usable water. But so far, the costs of desalin... |

When other things are small, others compensate... The Chinese have the largest wall (The Great Wall), the largest dam (Three Gorges) and now the longest sea-crossing bridge. It is 22-mile (35 km) long and its builders say it is the world's longest sea-crossing structure, being oficially linked-up on Tuesday nea... |

Canadian oceanographers are puzzled by bizarre photographs showing the skeleton of a large mammal popping out of an iceberg drifted near the coast of eastern Newfoundland. The six images reveal what looks like a brown rib cage and spinal column, slightly bent, sticking out of the iceberg. "Researchers throughout Cana... |

If you think that the deep cold waters of Antarctica have no life, forget it. A new research of the Antarctic Benthic Deep-Sea Biodiversity Project (ANDEEP) has found over 700 new species in the depths of the Southern Ocean (the Indian, Atlantic, and Pacific Oceans surrounding Antarctica). Amongst the species found ... |

This is the strangest sea in the world. It is not even a real sea, but the largest lake in the world by area: the Caspian Sea measures 371,000 square km (143,244 square mi), almost as much as California and is located between Europe and Asia. But this lake is salty, even if its salt concentration represents just one... |

Water is the blood of planet Earth and its circuit maintains it alive. And this cycle implies rivers, lakes, seas and oceans. Here are some of their records. The largest running water in the world is the Amazon river. Each second, this enormous river disgorges 150,000 cubic meters of water into the Atlantic Ocean (3,... |
