Jason Farmer for RedOrbit.com There are a number of sharks that have specialized light-emitting organs on their undersides that allow them to glow in the darkest depths of the ocean. In fact, according to researchers, at least 10% of all known shark species are luminous, and this ability is one of the most mysterious areas of shark biology. A new study of a tiny predator known as the Smalleye pygmy shark (Squalious aliae), led by Dr Julien Claes from the Catholic University of Louvain...

SEATTLE - There may never be a campaign to save the Puget Sound ratfish; no one really loves the ugly fish with rodent-like front teeth. But when a rare albino ratfish was found during a marine survey this past summer, scientists decided it was time to educate the public about the most abundant fish in local waters. The cartilaginous cousin of skates and rays is usually brown or black with white spots so it can blend in with the bottom of the sound, where it uses its rat-like teeth to crush...

PARIS (AFP) -- Marine biologists say they have obtained the first proof that sharks can spot changes in magnetic fields, boosting evidence that the fish have an internal compass to guide them as well as a phenomenal sense of smell. A Hawaii University team trained six sandbar sharks and one scalloped hammerhead shark to associate food with an artificial magnetic field, they report in a publication of Britain's Royal Society. The field, derived from a copper coil surrounding the sharks'...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
