Scientists have discovered that humpback whales possess the remarkable ability to create and use tools, enhancing their hunting strategies.
Capture Krill more Effectively
Specifically, these marine mammals have been observed forming bubble nets to catch targeted prey, showcasing their intelligence and adaptability, according to Tech.
Recent research published in Royal Society Open Science reveals that humpbacks, or Megaptera novaeangliae, employ complex bubble structures while hunting alone in the waters off southeastern Alaska.
These intricate bubble nets, which are composed of a series of bubbles shaped in specific configurations, allow the whales to more effectively capture krill and small fish, according to Dr. Lars Bejder, director of the Marine Mammal Research Program (MMRP) at the University of Hawaii.
Dr. Bejder explained, “We found that solitary humpbacks create elaborate bubble nets to catch krill, a small shrimp-like creature. This technique allows them to gather their prey more efficiently without expending excessive energy.”
Used Non-Invasive Tags
Dr. William Gough, an expert in marine biomechanics and ecology with MMRP, emphasized the importance of these hunting tactics for the whales' survival in the cold Alaskan waters, particularly before their long migration to Hawaii, where they care for their young.
Modern technology has played a crucial role in these findings. Researchers utilized non-invasive tags attached to the whales using suction cups, along with drones, to collect data on their movement patterns during the study.
These insights not only deepen our understanding of humpback whale behavior but also hold implications for conservation efforts. Understanding the hunting strategies of these magnificent creatures is essential for protecting their natural habitats and ensuring their future in the oceans.
