What is it called when whales make noise?

What makes a rorqual whale unique?
Rorquals are distinguished from other baleen whales by the presence of ventral grooves extending from the chin and lower jaw margins down the throat to the belly. These allow the mouth cavity to expand into the throat and make gulp-feeding practical (see cetacean: Feeding adaptations).
What are three features that determine whether a baleen whale is a rorqual?
Rorquals have a number of anatomical features that enable them to do this, including bilaterally separate mandibles, throat pleats that can expand to huge size, and a unique sensory organ consisting of a bundle of mechanoreceptors that helps their brains to coordinate the engulfment action.
What noise does a sperm whale make?
Sperm whale vocalizations include directional clicks, from less than 100 Hz to 30 kHz. The majority of energy in these clicks is in the 5 to 25 kHz range. In addition to echolocation, in social situations, sperm whales produce repeated patterns of clicks called codas (see How do marine mammals communicate using sound?
Can humans hear whale sounds?
Humans can only hear part of the whales’ songs. We aren’t able to hear the lowest of the whale frequencies. Humans hear low frequency sounds starting at about 100 Hz. Researchers have noted that whale songs sound very similar to the songs of hoofed animals, such as.
Is the blue whale a baleen whale?
Diet of krill During certain times of the year, a single adult blue whale consumes about 4 tons of krill a day. Blue whales are baleen whales, which means they have fringed plates of fingernail-like material, called baleen, attached to their upper jaws.

— Author: Karen Weintraub, Anchorage Daily News, “Baleen whales intermingled as they evolved, and share DNA with distant cousins,” 7 Apr. 2018 Instead, the species, all part of a group called rorquals, have evolved more into a network, sharing large segments of DNA with even distant cousins.
