Water depth and the type of habitat — rocky, sandy or coral reef — also played roles in the approaches the whales took. Drone imagery shows a gray whale using a side-swim technique to find food.
The melon is structurally part of the nasal apparatus and comprises most of the mass tissue between the blowhole and the tip of the snout. The function of the melon is not completely understood, but scientists believe it is a bioacoustic component, providing a means of focusing sounds used in echolocation and creating a similarity between characteristics of its tissue and the surrounding water ...
When they swallow they stream the water out through their baleen as they ingest the fish. [3] 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]
Cetacea (/ s ɪ ˈ t eɪ ʃ ə /; from Latin cetus 'whale', from Ancient Greek κῆτος () 'huge fish, sea monster') [3] is an infraorder of aquatic mammals belonging to the order Artiodactyla that includes whales, dolphins and porpoises.
The motion of the head may induce a bow wave in the fluid which pushes the prey away from the jaws, but this can be avoided by allowing water to flow through the jaw. This can be accomplished by means of a swept-back mouth, as in balaenid whales, [21] or by allowing water to flow out through the gills, as in sharks and herring.
Researchers studying the majestic creatures have discovered the animals aren't just jumping for fun -- it's an important way to communicate.
Humpback whale breach sequence. A breach or a lunge is a leap out of the water, also known as cresting. The distinction between the two is fairly arbitrary: cetacean researcher Hal Whitehead defines a breach as any leap in which at least 40% of the animal's body clears the water, and a lunge as a leap with less than 40% clearance.

Whales sing loud enough that their songs travel through the ocean, but knowing the mechanics behind that has been a mystery. Scientists now think they have an idea, and it's something not seen in ...
