Researchers succeeded this month in using sedatives fired from a dart gun to calm down and free an endangered North Atlantic right whale tangled in fishing line.
The new tactic was used Jan. 15 off the Florida coast to free a young right whale from 50 feet (15 meters) of line wrapped through its mouth and around its flippers. A satellite monitor attached to the whale shows it survived.
The same team used the tactic once before, in early 2009 on another whale.
Researcher Michael Moore of the Woods Hole Oceanographic Institution called it a big step.
Scientists say sedation could be another tool available to rescuers trying to free whales from tangles of manmade line that would normally prove fatal.
