TOULOUSE, France - Airbus SAS is emulating a marine predator to take a bite out of Boeing Co's home market.

The world's largest planemaker will fit so-called sharklets to the wings of the A321 single-aisle jet to enhance its range.

The eight-foot-high extensions are available from 2012 for 900,000 euros ($1.1 million) and promise to add 100 nautical miles to the aircraft's reach or increase its payload by as much as 1,100 pounds.
