Scientists have published new descriptions of a range of jelly-like animals that were originally filmed and photographed during a series of dives in the deep oceans of the Arctic in 2005, BBC News reported. Experts say one of the types of jellyfish discovered in the Arctic, which is isolated from much of the water elsewhere on the globe, is completely new to science. The Canadian Basin is one area of the Arctic that is cut off by deep-sea ridges that isolate any species there from other...

Since the days of Charles Darwin, researchers are interested in reconstructing the "Tree of Life", and in understanding the development of animal and plant species during their evolutionary history. In the case of vertebrates, this research has already come quite a long way. But there is still much debate about the relationships between the animal groups that made their apparation very early in evolutionary history, probably in the late Precambrian, some 650 million years ago. An...

Researchers reported on Friday that huge swarms of stinging jellyfish and similar slimy animals are ruining beaches in Hawaii, the Gulf of Mexico, the Mediterranean, Australia and elsewhere. According to the report, 150 million people are exposed to jellyfish globally each year, with 500,000 people getting stung in the Chesapeake Bay, off the U.S. Atlantic Coast, alone. There is another 200,000 getting stung every year in Florida, and 10,000 are stung in Australia by the deadly Portuguese...

Earth's first animal was the ocean-drifting comb jelly, not the simple sponge, according to a new find that has shocked scientists who didn't imagine the earliest critter could be so complex. The mystery of the first animal denizen of the planet can only be inferred from fossils and by studying related animals today. To get to the bottom of that, scientists analyzed massive volumes of genetic data to define the earliest splits at the base of the animal tree of life. The tree of life is...

A new study mapping the evolutionary history of animals indicates that Earth's first animal--a mysterious creature whose characteristics can only be inferred from fossils and studies of living animals--was probably significantly more complex than previously believed. The study, which was funded by the National Science Foundation (NSF), is the cover story of the April 10, 2008 issue of Nature. Using new high-powered technologies for analyzing massive volumes of genetic data, the study defined...

A study led by Brown University biologist Casey Dunn uses new genomics tools to answer old questions about animal evolution. The study is the most comprehensive animal phylogenomic research project to date, involving 40 million base pairs of new DNA data taken from 29 animal species. The study, which appears in Nature, settles some long-standing debates about the relationships between major groups of animals and offers up a few surprises. The big shocker: Comb jellyfish "“ common and...

Giant jellyfish have been spotted in large numbers in the usually chilly waters surrounding Norway, an Oslo University scientist reported. Hege Vestheim told the Tonsbergs Blad newspaper that she photographed large numbers of the giant comb jellyfish in Norwegian waters last fall. The comb jellyfish, while not dangerous to humans, eats small newly hatched fish and can devastate marine fisheries by disrupting food chains. They were drifting on the surface everywhere, Vestheim told...

The Lion's Mane jellyfish (Cyanea capillata) is native to the northern regions of the Arctic, Atlantic and the Pacific Oceans; there are very few Lion's Mane jellyfish that can be found farther south than 42 degrees north latitude. The Lion's Mane jellyfish is the largest and longest jellyfish known and one of the longest animals in general. In 1870, a Lion's Mane jellyfish was found washed up on the Massachusetts Bay. The bell (body) of the jellyfish had a diameter of 7 feet and 6 inches...

Giant Grenadier, Albatrossia pectoralis
2009-01-17 21:09:53

The Giant Grenadier (Albatrossia pectoralis) is a species of rattail fish that is found in the north Pacific from northern Japan to the Okhotsk and Bering seas, east to the Gulf of Alaska, and south to northern Baja California in Mexico. It occurs at depths between 450 and 11,500 feet. This specimen grows to about 7 feet long. It has the usual greatly elongated pointed tail of the rattails. The snout is low, slightly protruding beyond the large mouth. The scales are small and slightly...

  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
