Nature is the most potent source of inspiration for just about every aspect of human activity, from painting and music to nanotechnology and, apparently, underwater biomimetic probes. Two experts at the Michigan State University (MSU) have recently taken it upon themselves to create robotic fish, made out of advanced... |

Once upon a time, aquaculture was not one of the well-developed branches of food production. It fact, its contribution to the total amount of fish the world's population consumed was negligible. This is no longer the case today. A new report from an international group of scientists comes to show that more than ... |

The amazing ability that fish have of essentially touching objects around them without actually coming in physical contact with them comes from their unique sensory system, called the lateral-line. This allows them to sense obstacles in their paths, and to steer clear of predators. Robotics engineers are currentl... |

Collecting live information from inside fish colonies and marine ecosystems was never an easy task for naturalists and documentary reporters. The human factor is always tainting the results of studies, and it therefore needs to be eliminated. This is precisely what a new type of robotic fish will do, in addition to p... |

A new comparative research has revealed the fact that the main factor creating differences between fish production levels in clear mountain lakes and brown forest lakes is light, and not access to nutrients, such as previously held. The counter-intuitive discovery was made by experts at the Climate Impacts Research C... |

In their analysis of human remains dating back more than 40 millennia ago, researchers have determined that at least one of our ancestors ate fish regularly. The find helps set another piece in the puzzle of human development, and offers a better understanding of the diets that people had long before the first modern... |

A small and otherwise harmless water snake has learned a neat trick, which ensures that unsuspecting fish commit suicide via snake mouth (and die from it) a large number of times. Coiled up in a specific position, the water snake expects its prey to approach, and then scares it away with a single body move; unfortuna... |

Experts at the University of California in San Diego (UCSD) Scripps Institution of Oceanography (SIO) have recently discovered in a new study that high levels of the dangerous greenhouse gas carbon dioxide (CO2), which is largely blamed for global warming, also cause numerous mutations in fish. Among these, they high... |

The sea lamprey is one of the weirdest fish in the oceans, and is a direct descendant of animals that lived millions of years ago. This earned it the classification of “living fossil,” because it also looks very strange, as if from a different time. Now, researchers have discovered that there's more ... |

A new scientific study, conducted by researchers at the St Andrews and Durham universities, shows that some fish species may have an innate ability to learn that is similar, pattern-wise, to that humans have. According to the joint team, the common nine-spined stickleback could be the first fish discovered to employ ... |

Naturalists have known for a long time that different types of environments play a crucial part in the development of new species, as well as in the extinction of new ones. However, thus far, no one has been able to prove the contrary. Following a rigorous series of scientific experiments, experts from the University... |

Experts at the Natural History Museum in London, the UK, were puzzled to learn that they had had specimens of a new species of fish in custody for more than a year. Upon initial inspection, they thought that the animals belonged to a different family, and left them to go about their business in captivity. A year late... |

1. Gannets and boobies are coastal seabirds famous for their dive for fish.

Pelicans look like birds hailing from prehistoric times. Truth is, they are precisely that.

Today, only 8 species of pelicans can be ... |

Sharks are extremely sensitive to electric fields, and this enables them to detect their preys, as all living creatures emit weak electric fields. But this ability of the sharks comes with pros and cons: in captivity, sharks avoid metals reacting with seawater and producing an electric field. In fact, this may be the... |
