1. Unhomogenized milk naturally separates into a small layer of fatty liquid (called cream) and a layer of nearly fat-free liquid (called skim milk). Skimming off the top layer produces the dairy product cream. Modern techniques of cream production involve separating whole milk through the use of centrifuges, greatly speeding up the process.
opah. n. 1. (Animals) a large soft-finned deep-sea teleost fish, Lampris regius (or luna), of the Atlantic and Pacific Oceans and the Mediterranean Sea, having a deep, brilliantly coloured body: family Lampridae. Also called: moonfish or kingfish.
With its tire-sized frame and awkward fins, it would be easy to mistake the opah fish for the oaf of the ocean. The fish, which swims hundreds of feet beneath the surface of the sea in frigid waters, is an oceanic predator thanks to a secret evolutionary trait -- its warm blood.
