The fish that they ingest are also a source of hydration for them. [3] Bubble netting is an advanced and necessary feeding method developed by humpback whales to feed multiple mouths at one time. Humpback whales do not always feed in large groups. [5] On their own, they may engage in similar method referred to as lunge feeding. [7]
A group of whales swim in a shrinking circle, blowing bubbles below a school of prey fish. [22] Forage fish show a strong fear of bubbles and can be easily contained within a bubble curtain. [23] The shrinking ring of bubbles encircles the school and confines it in an ever smaller cylinder.

Baleen whales can have streamlined or large bodies, depending on the feeding behavior, and two limbs that are modified into flippers. The fin whale is the fastest baleen whale, recorded swimming at 10 m/s (36 km/h; 22 mph). Baleen whales use their baleen plates to filter out food from the water by either lunge-feeding or skim-feeding
Japan's Fisheries Agency has proposed a plan to allow catching fin whales in addition to three smaller whale species currently permitted under the country's commercial whaling around its coast ...
Whales are more likely to breach when they are in groups, suggesting that it is a non-verbal signal to other group members during social behaviour. Scientists have called this theory "honest signalling". The immense cloud of bubbles and underwater disturbance following a breach cannot be faked; neighbours then know a breach has taken place.
