Hideaki Akaiwa was at work on March 11th when the earthquake and then the tsunami hit his hometown, Ishinomaki in Japan’s Miyagi Prefecture. The city was covered with water ten feet deep -for days. Hideaki’s wife was missing somewhere in the flooded area. Rescue workers told Hideaki that all they could do was wait for the military to come help. But the 43-year-old man did not want to sit idly by while his wife was missing, so he put on some SCUBA gear.The Aurora from Terje Sorgjerd on Vimeo.
Rendell and his collaborators, including biologists Hal Whitehead, Shane Gero and Tyler Schulz, have for years studied the click sequences, or codas, used by sperm whales to communicate across miles of deep ocean. In a study published last June in Marine Mammal Sciences, they described a sound-analysis technique that linked recorded codas to individual members of a whale family living in the Caribbean.The video above (not part of the study) has several minutes of clicks.
In that study, they focused on a coda made only by Caribbean sperm whales. It appears to signify group membership. In the latest study, published Feb. 10 in Animal Behavior, they analyzed a coda made by sperm whales around the world. Called 5R, it’s composed of five consecutive clicks, and superficially appears to be identical in each whale. Analyzed closely, however, variations in click timing emerge. Each of the researchers’ whales had its own personal 5R riff...
Moreover, 5R tends to be made at the beginning of each coda string as if, like old-time telegraph operators clicking out a call sign, they were identifying themselves. Said Rendell, “It may function to let the animals know which individual is vocalizing.”..
That individual whales would have means of identifying themselves does, however, make sense. Dolphins have already been shown to have individual, identifying whistles.
