"Mysterious Whale Die-off Is Largest on Record"

"Mass death among baby right whales has experts scrambling to figure out the puzzle behind the largest great whale die-off on record.

Observers have found 308 dead whales in the waters around Peninsula Valdes along Argentina's Patagonian Coast since 2005. Almost 90 percent of those deaths represent whale calves less than 3 months old, and the calf deaths make up almost a third of all right whale calf sightings in the last five years."
