Dolphin and seal remains dated 30.000 to 60.000 years ago were recently discovered in Vanguard and Gorham's caves on the Rock of Gibraltar, along with flint knives used by Neanderthals. This leads to the conclusion that Neanderthals, besides eating land grub, were skilled and adaptive enough to hunt sea mammals.... |

Dolphins are considered the fastest sea mammals. Smaller dolphins reach 35-40 km (22-25 mi) per hour, but the orca or killer whale, that is in fact the world's largest dolphin, reaches 54 km (33 mi) per hour, which is a lot in the water. The question is: why not faster? The answer is given by a new research publ... |

A man will spend money on expensive gifts, best wine, finest sweets and flowers. But in the murky waters of the Amazon, boto or the Amazon River dolphin (Inia geoffroyensis) (which also inhabits the Orinoco River) males offer branches, rocks, weeds and lumps of clay to their females, in a parade also intended to cha... |

The killer whale, or orca, is one of those animals with an unmistakable color pattern that cannot fool even an uninitiated person. But now, researchers have taken pictures of a white killer whale near the Aleutian Islands (western Alaska). The beast of the myths turned into reality."I had heard about this whale, but ... |

1. The killer whale or orca is, together with the Great White Shark, the top predator of the oceans. The name of "whale" is deceptive, as this cetacean is not even a toothed whale, but a dolphin. That's right, the largest of all: males can be up to 8 m (26 ft) long and weigh up to 8 tonnes. The mouth is adorned ... |

It has already been known that each dolphin population has its own dialect or even "language", which cannot be understood by a "foreigner" dolphin, as it is learned. But a new research made by PhD candidate Liz Hawkins, from Southern Cross University's Whale Research Centre, in Lismore, revealed that the dolphin... |

Human ear cannot detect sounds that have frequencies lower than 20 Hz (infrasounds) or over 20 kHz (called ultrasounds). That's why some species may appear quite silent for us, while in fact they are very noisy... We only lack their hearing to figure this out.1.Dolphins and toothed whales are famous for their so... |

Try to hold your breath for more than 2-3 minutes, and those around you will have to call the ambulance. But the sperm whale can dive for more than one hour to depths greater than 1,200 meters (roughly 4,000 feet), with average dives of 45 minutes, to depths of 600-1,000 meters (1,968 to 3,280 feet). Elephant seals c... |

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... |

For a long time now, humans have been fascinated by the spectacular fights between the huge sperm whales and giant squids, that triggered the myth of the kraken, the island big sea monster. But how do the whales manage to detect the squids in the complete darkness of the deep ocean? It's all in their ultrasound ... |

All vertebrates sleep, from fish to mammals. And even some invertebrates, like the insects. During sleep, the body enters in a predominantly anabolic phase, when it develops, grows, heals and builds muscle; the immune system is at its peak (that's why, when we're ill, we wake up without the cold). The lack ... |

Dolphins are swimming not only in the sea, but also in the rivers. Or at least they used to. One of the three known species of freshwater dolphins, the Chinese one, is now "likely to be extinct"(the other two species inhabit Ganges and Indus and Amazon, respectively). An American-British-Japanese-Chinese research tea... |

We, humans, live in a visual world. 90 % of our information concerning the environment comes through our eyes. But if we refer to cetaceans (dolphins and whales), their world is mainly auditive. These animals practically "see" with their ears, employing the ultrasound ecolocation, as vision in the water is greatly im... |

Albino individuals usually do not survive in nature, that's why they are such a rare view. Recently an albino ibex goat has been spotted in the Italian Alps. Now Erik Rue, a charter-boat captain from Lake Charles, Louisiana, has come with photographs of a rare pink dolphin, captured on images a couple of weeks a... |

People have been amazed since Antiquity by dolphins' intelligent behavior. 2,000 years ago, the Greek poet Opian said "The dolphins are humans that at the demand of the Dionysus (a Greek god) changed the ground with the sea, taking fish shape". The high intelligence of the dolphins is regarded as a reaction to ... |

Cetaceans (whales and dolphins) emerged 50 million years ago. Believe it or not, they have a common origin with …the hippopotamus (!), not with the land predators. Currently, there are 15 species of baleen whales and 74 toothed whales (out of which 42 are dolphins). The largest whale (and animal that has ever existed... |
