What Divers Should Know About Humpback Whale

With their remarkably long pectoral fins—often a third of their body length—and a head adorned with distinctive, nerve-rich tubercles, the humpback whale (Megaptera novaeangliae) is an unmistakable sight. These majestic baleen whales typically measure 14–17 meters (46–56 feet) and can weigh up to 40 metric tons, making them substantial encounters in open water. Their bulky bodies feature unique color patterns and scars on their jagged-edged tail flukes, allowing individual identification by keen observers.

Found in oceans and seas worldwide, these rorquals undertake extensive migrations from polar feeding grounds to warmer breeding areas near the equator. Divers in shallower breeding waters might witness mothers with calves, or even hear the complex, prolonged songs produced by males, which can last for over half an hour. While primarily known for spectacular surface behaviors like breaching, humpbacks also employ bubble-net feeding, a remarkable cooperative strategy to catch their diet of krill and small fish. Encounters with these awe-inspiring animals often involve observing their unique interactions with their environment, from barnacles hitching rides on their skin to their distinctive feeding methods.
