Who doesn’t like to hear a good whale story? Humpback whales in particular never cease to amaze with each new discovery. Scientists recently discovered that humpback whales can not only use tools, but are also adept at making and modifying tools to improve their hunting skills.

This remarkable behavior sheds light on their intelligence and social structures and reveals a cognitive ability that challenges our understanding of marine life.

These magnificent creatures are not just gigantic inhabitants of our oceans; they are also active participants in their complex marine habitat and play a crucial role in the ecosystem.

At the forefront of this astonishing revelation is Professor Lars Bejder, the distinguished director of the Marine Mammal Research Program (MMRP) at the University of Hawaii.

Bejder, along with his dedicated and meticulous team of researchers and marine biologists, had conducted extensive studies on humpback whales in Southeast (SE) Alaska.

This area is known to be an important food source for these magnificent marine animals, providing abundant nutrients and prey that they need to feed.

Their discovery was nothing short of dramatic and groundbreaking: humpback whales not only survive in this habitat – they actively shape it.

Their feeding habits and social behavior play a crucial role in the local ecosystem, influencing everything from the distribution of prey species to the overall health of marine habitats.

The scientists discovered the whales’ extraordinary technique of building complex “bubble nets” to catch their prey.

The whales control the size, depth and distance of these bubbles, making their hunting process efficient and energy-saving. This clever strategy allows them to catch seven times more prey in a single dive.

Meaning of “bubble nets”

Humpback whales are known for their complex songs and acrobatic jumps that fascinate anyone lucky enough to observe them.

However, survival in the vast oceans requires efficient hunting and strategic adaptability, even for humpback whales.

These magnificent animals embark on an incredible migration, traveling thousands of miles to overwinter in the warm, inviting waters of Hawaii where they can breed and raise their young.

The calories they accumulate during the feeding season are crucial to them, as they rely on this energy to sustain themselves during their long journey.

According to Professor Bejder, a leading expert in marine biology, “hunting success is the key to whale survival.”

This success is largely due to their remarkable bubble-net strategy, in which groups of whales work together to create an impressive optical bubble display that traps schools of fish.

It is not new that we know that animals use tools. What sets humpback whales apart, however, is their ability to make and modify these tools.

This extraordinary ability gives us insight into their intelligence and adaptability in their natural habitat.

Studying these underwater giants is no easy task, but thanks to technological advances, scientists can observe their behavior like never before.

William Gough of the MMRP and his team used non-invasive suction cup tags and drones to track the whales’ movements and collect data.

“We have placed non-invasive suction cup tags on whales and flown drones over solitary humpback whales in southeast Alaska that are caught with bubble nets,” Gough explained.

Future of nature conservation in the face of threats

While we admire the intelligence of whales, we must not lose sight of the bigger picture: the vital need to protect them.

The study’s much-needed insights will help pave the way for effective conservation strategies by deciphering the feeding behavior of these animals and thus ensuring the conservation of their feeding grounds.

“This little-studied foraging behavior occurs exclusively in humpback whales,” notes Gough.

Dr. Andy Szabo, executive director of the Alaska Whale Foundation (AWF), highlighted the remarkable adaptability of humpback whales in the face of ecological challenges.

Although threats to our marine ecosystems persist, whales’ behavioral flexibility could be their salvation.

What lies ahead for humpback whale research

The discovery that humpback whales use tools represents a significant development in marine biology and paves the way for further research.

By collaborating with research institutions such as MMRP and AWF and using cutting-edge technology, we are on the verge of learning even more about these fascinating creatures and their complex interactions with the marine ecosystem.

Ultimately, the ultimate goal is to protect these incredible creatures. Only by understanding their behavior and ingenuity can we acquire the knowledge and tools we need to protect them.

The full study was published in the journal Royal Society Open Science.
