Orest Diachok, a research physicist at Johns Hopkins University, told Discovery News that the killer whale study provides "compelling evidence on the function of tail slaps, much more compelling than previous studies of this phenomenon."
As for the herring flatulence, Diachok
agreed the fish may do this to facilitate escape, but he
said it also might just be inadvertent.Diachok
team discovered that whales use similar bubbles to their own advantage.
colleagues believe whales may even classify fish before they catch them.
explained, "If one humpback transmits a series of tones, like plucking all the strings of a harp, then the listening (bottom) whale may notice that he
can hear all of the tones, except for the one, which corresponds to the resonance frequency of fish swim bladders when the school of fish is swimming between the transmitting and listening whale."
