Blue whales, the largest animal on Earth, once had an estimated population of more than 350,000 worldwide. Decimated by hunting, they now likely number fewer than 10,000. Learn more: http://ow.ly/Lkh950JhNqg | Canada Post

An Adult Blue whale attempts to escape a group of hungry and determined Orcas in the gulf of California. Fun fact: The Blue Whale population was once estimated to be around 350,000 animals…but when commercial whaling rolled around, those numbers dwindled significantly nearly wiping out the species entirely. It is now estimated that there are between 10,000 to 25,000 blue whales left. Luckily, blue whales are a protected species against whaling but still face threats due to human interference (sh

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.
