Whales Have Regional Dialects
By Chad Upton | Editor
It’s pretty common knowledge that whales, dolphins and various porpoises “speak” to each other in a language we don’t completely understand. Sperm whales in particular, speak in a series of clicks called “codas.”
Much like we recognize the voices of our friends, whales can tell which member of their group is clicking. Also like people, researchers have discovered that whales from different regions have distinct accents.
Sperm whales have a call known as the “Five Regular” which is used by sperm whales worldwide. It’s a series of five evenly spaced clicks believed to be used for individual identity.
This communication is very useful for navigating in dark waters — whales can dive as deep as 1000 meters (3280 ft)!
