Oil spill threatens Puerto Rican sea life

Pristine areas of Puerto Rico's southwestern shore have come under danger due to a mysterious oil spill. Despite efforts by the U.S. Coast Guard to clean up the mess, officials are investigating where the spill originated from:

"We don't know exactly what it is. It's a black, oily, tar-like substance," (Coast Guard spokesman Ricardo) Castrodad said. "The aerial view showed four or five patches, each of up to 500 yards long and 50 yards wide, spread out about five miles."

The cleanup efforts are expected to take several weeks though that could be delayed by inclement weather.
