Study: Stranded dolphins often deaf [View All]

[Generic Other]

WASHINGTON, Nov. 15 (UPI) -- U.S. researchers say dolphins found weakened or dead near shore often have one thing in common -- they are nearly deaf.

University of South Florida scientists say in a marine world where hearing is as vital as sight dolphins unable to use sound to locate food or find family members often wind up weak and disoriented, The Washington Post reported Monday.

The National Oceanic and Atmospheric Administration says 1,200 to 1,600 whales and dolphins are found stranded off the U.S. coast each year.

Without the ability to hear sounds, researchers say, dolphins can be helpless.
