These two MP3 sound clips of sperm whales were recorded in July 1997 with custom Cetacean Research™ hydrophones designed specifically for National Geographic's Crittercam The two sets of images below the links to the sound clips are plots made from different segments of the sounds. Roll over an image to see an enlargement below.
Actual video footage from a sperm whale's point of view can be seen in National Geographic Television's video "Sea Monsters: Search for the Giant Squid". This television special was first broadcast on 25 February 1998 and won an Emmy Award for Best Sound, thanks to Cetacean Research™ hydrophones..

The sound clips are in either MP3 or WAV format. If you need a player, we have some on our links page.
