A large pod of endangered Arabian Sea humpback whales — more than six individuals — was recently spotted off the coast of Gwadar, Balochistan. This sighting is one of the largest ever recorded in Pakistan and a promising sign of recovery for a species that has long struggled to survive. From 1963 to 1967, Soviet whaling fleets operating in the Arabian Sea, including off Pakistan’s coast, targeted humpback whales, severely depleting their numbers. Since then, this unique population, which is the

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
