109 seconds of breathing with whales 🐳 #EarthDay There are two types of whale; baleen and toothed, separated by the way in which they feed. Baleen whales, such as the blue whale, have sheets instead of teeth which sieve prey like zooplankton or krill from the ocean. Whales help the planet stay healthy in a number of ways. As they surface for air they release huge faecal plumes, nourishing the ocean and helping to support the food chain. They even help the environment after they die, with their

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. The
