Humpback whales may not have hands, but that doesnt mean they arent handy.
The whales in question were spotted by researchers off the coast of Alaska in July 2019.
For the next two years, the researchers returned for more expeditions and kept measuring the bubble nets.

They ended up documenting hundreds of bubble nets over that time, created by dozens of individual whales.
All the documented nets contained multiple circular rings of bubbles, with each successive ring smaller than the last.
Instead, the benefit could be rounding up more food in a bite.
No wonder future aliens are sodesperateto talk to humpback whales.
