Ships searching for the faint black-box signals of Malaysia Airlines Flight 370 on Friday ran into some problems: Whales and other sea creatures may be interfering with the search in the Indian Ocean, NBC News reported. Australian authorities said one possible ping was detected but was quickly discounted. “False alerts may be experienced from biological sources such as whales or interference from shipping noise,” the Australian Joint Agency Coordination Center said.

Crews searching for the jet launched a targeted underwater hunt on Friday, April 4 for the plane's black boxes along a stretch of remote ocean, with just days left before the devices' batteries are expected to run out. The Ocean Shield, which is dragging a towed pinger locator from the U.S. Navy, and the British navy's HMS Echo, which has underwater search gear on board, will converge along a 240-kilometer (150-mile) track in a desolate patch of the southern Indian Ocean, said Angus Houston, the head of a joint agency coordinating the search.
