Incredible moment humpbacks create ‘bubble net’ to lure fish to surface
The incredible teamwork of a pod of humpback whales has been captured in stunning high definition footage as they create a ‘bubble net’ to catch fish.
The technique has been seen before in these intelligent marine mammals, but it is rare to capture on film and at close range.
The moment was caught by Berthold Hinrichs in the Norwegian Sea off Skjervoy, in the north of Norway this week.
Fish are seen jumping from the water after being driven upwards by the group of whales. This is a classic technique for generating a ‘bubble net’ used by hunting whales.
Research into whales and dolphins has shown they can learn as individuals and can pass on their knowledge to others.
Individual learning was previously believed to be an exclusively human trait.
However, other animals such as whales have shown examples of individual and team learning, as opposed to a genetic hardwiring for displaying certain behaviours.
To communicate, whales touch fins with each other, vocalise and slap fins on the water.
Humpback whales are famous for their ‘song’, with males producing a long series of calls that are normally heard during the winter breeding season.
They may repeat the song for several hours. Despite increasing awareness of the threats to whales, the biggest issues to their numbers include being hunted by nations such as Japan, ship strikes, pollution, and entanglement in fishing gear.
