BREAKING: Prepare to dive underwater with a blue whale. Yes really. The Goldbogen Lab at Hopkins Marine Station of Stanford University attached suction-cup cameras to whales, to study the lunge-feeding behaviour, which allows them to become so big. They've passed on this incredible footage. The Big Blue Live team have been lucky enough to join the Hopkins team on the boat, so make sure you tune in to BBC One on the 23rd, 27th & 30th August and PBS on the 31st Aug, 1st & 2nd September for more ex

Blue whale vocalizations are very low frequency sounds with some in the 15 Hz range. These tones characteristically travel long distances due to the high power, but also due to very long-wavelengths (over 300 feet for 15 Hz). This enables their songs to be heard thousands of miles from the source. We can assume that the projection distance is important (Nature can be extravagant, but she is never wasteful), but we can only speculate why they need to broadcast their songs across ocean basins.
