Dolphins Call Each Other by Name!
February 23, 2013 8 Comments
A new study published in Discovery News says that dolphins call each other by name! Researchers found that each dolphin has a signature whistle that acts as a name. When separated, dolphins use that whistle to search out and call for the missing dolphin. The complete article is at: (http://news.discovery.com/animals/whales-dolphins/dolphins-call-each-other-by-name-130219.htm).
The attached pictures show wild dolphins at Monkey Mia, Australia (north of Perth). Researchers there have been continuously studying dolphins for over 30 years. The dolphins are famous because they are the only ones in the world known to use tools!
The dolphins carry basket sponges on their beaks, and use them to probe for food on the sea bottom. This technique has been passed down from mother to offspring for at least 180 years. Although tool-using dolphins tend to be solitary and make up only 5% of the population, the latest research says that these “nose-wearing spongers” simply prefer the company of other “spongers”. Fascinating!
