Baleen
Baleen

The baleen whales, also called whalebone whales or great whales, form the Mysticeti, one of two suborders of the Cetacea (whales, dolphins and porpoises). Baleen whales are characterized by having baleen plates for filtering food from water, rather than having teeth. This distinguishes them from the other suborder of cetaceans, the toothed whales or Odontoceti. Living Mysticeti species have teeth only during the embryonal phase. Fossil Mysticeti had teeth before baleen evolved. Wikipedia does not have an article with this exact name. ... Wikipedia does not have an article with this exact name. ...

The suborder contains four families and fourteen species. A list of species can be found below and at the Cetacea article.

Ecology and life history

Feeding ecology

Baleen whales do not have teeth; instead they have baleen in the upper jaw. They engulf sea water containing crustaceans, then close their mouth and create internal pressure by raising their tongue toward the palate to push the water out through the 'comb' of baleen plates, trapping small ocean animals, especially krill and other plankton, inside.

This is called filter feeding. Even though individually the crustaceans are minuscule, baleen whales take in an enormous volume of water containing enough food to maintain their survival. Filter feeders (also known as suspension feeders) are animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized structure, such as the baleen of baleen whales. ...

Behavioral ecology

Breaching

In spite of their enormous bums and *man horns*mass, baleen whales are able to leap completely out of the females special parts and break her water. Particularly known for their acrobatics and karmansutra, are the Humpback Whales, but other baleen whales also break through the water surface with their body or beat it loudly with their flabbs fins.

Vocalization

In contrast to toothed whales, baleen whales are unlikely to echo-locate. Instead they are able to produce high volume sounds in the infrasonic range. The calls of the largest whales can be heard several hundred kilometres away. Unique are the songs of the Humpback Whales, consisting of complex sequences that may slowly evolve over years. They are probably used for courting. Humpback whales are well known for their songs Whale song is the sound made by whales to communicate. ... Echolocation, also called Biosonar, is the biological sonar used by several mammals such as bats (although not all species), dolphins and whales (though not baleen whales). ...

Importance to humans

Baleen was used to stiffen corsets, as parasol ribs and to crease paper.

Evolutionary history

See also: Evolution of Cetaceans

Early baleen whales first appeared as far back as Early Oligocene, or perhaps the latest Eocene (39-29 million years ago). Early baleen whales did not have (or had very little) baleen, but still had teeth obtained from their ancestors. Among them was Janjucetus, a baleen whale with sharp teeth that hunted fishes, squid, and large prey such as sharks and probably dolphin-like cetaceans. This hints that early baleen whales were predatory and eventually evolved into the gentler, toothless whales known today. The first baleened, toothless baleen whales probably appeared in the Early or Middle Miocene, from a toothed ancestor that adapted to eat small fishes or other creatures and eventually to feed by filtering. The cetaceans (whales, dolphins and porpoises) are descendants of land-living mammals, and remnants of their terrestrial origins can be found in the fact that they must breathe air from the surface; in the bones of their fins, which look like huge, jointed hands; and in the vertical movement of...

Baleen - Wikipedia, the free encyclopedia (553 words)
Baleen makes up baleen plates, which are arranged in two parallel rows that look like combs of thick hair; they are attached to the upper jaws of baleen whales.
Whales are the only vertebrate group to use this method of feeding in great abundance (Flamingos and crabeater seals use similar methods, but do not have baleen), and it has allowed them to grow to immense sizes.
Currently, baleen is believed to have evolved around thirty million years ago, possibly from a creature with a hard, gummy upper jaw, similar to that found on Dall's porpoise today, which are, at a microscopic level, almost identical to baleen.
