By using echolocation toothed whales can determine many factors about their environment, such as how far an object is, how fast it is moving, whether it is above or below them, what direction it is traveling in, how large it is, and whether it is a hollow or solid object. They are believed to produce sound by moving air through tubed extensions of the larynx to nasal plugs located near the blowholes.

How are blue, right, fin, sei, humpback, fin whales, The pods stay together for years, sometimes even decades. In In summer months they move about in cold water seeking foraging areas where there are large concentrations of krill. Whales have a very acute sense of hearing and can detect sounds made by other whales from miles away, which can be important for mating or locating other whales in a pod. The name rorqual is derived from a Norwegian word, rockval, that means furrow, referring to the throat grooves.

Among these adaptations are: streamlined bodies for efficient movement through water; forelimbs modified into flippers to aid in steering; hind limbs internalized remnants reducing drag; tail positioned horizontally to achieve a powerful up and down propulsion; hair replaced with under-skin blubber to provide warmth and buoyancy; structure of nostrils changed to blowholes that can be sealed off under water and position shifted to top of head to give ability to breath air before the rest of the body surfaces and while swimming at the surface without lifting the head; highly developed hearing that relies on an internal system of air sinuses and bones to detect sound instead of external ears; lung capacity that enables them to exchange 80-90% of lung air volume(humans can exchange only 17-20%) ; reproductive organs internalized to prevent drag when swimming; and countercurrent heat exchangers in the tongue that enable the whales to take in gallons of very cold water during feeding and still not become hypothermic. Although they are not the most exciting animal to watch, their behavior can be interesting if one takes the time to observe them. These findings were also consistent with a previous study of humpback whale and Southern right whale mother-calf pairs.
