Baleen whales (/ b ə ˈ l iː n /), also known as whalebone whales, are marine mammals of the parvorder Mysticeti in the infraorder Cetacea (whales, dolphins and porpoises), which use baleen plates (or "whalebone") in their mouths to sieve plankton from the water.

2025年3月7日 · Baleen whale, (suborder Mysticeti), any cetacean possessing unique epidermal modifications of the mouth called baleen, which is used to filter food from water. Baleen whales seek out concentrations of small planktonic animals. The whales then open their mouth and take in enormous quantities of

There are 14 species of baleen whale including the blue, bowhead, right, humpback, minke and gray whale. Baleen whales are generally larger than toothed whales except for the sperm whale which is very big and has teeth. Many baleen whales migrate annually, travelling long distances between cold water feeding areas and warm water breeding areas.

Baleen is a filter-feeding system inside the mouths of baleen whales. To use baleen, the whale first opens its mouth underwater to take in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as a food source for the whale.

2025年1月7日 · Baleen whales, also called whalebone whales, are a group of marine mammals distinguished by numerous keratinized plates (instead of teeth) called baleen hanging from their upper jaw. They belong to the parvorder Mysticeti (hence also called mysticetes) under the infraorder Cetacea, which includes whales, dolphins, and porpoises .

2025年3月21日 · Some baleen whale fossils show the presence of both teeth and baleen, which indicates a gradual transition in their filter-feeding system. Further evidence of this can be seen during foetal development , with studies suggesting that baleen whale embryos initially develop teeth that are then reabsorbed before birth.

Baleen is the series of fringed plates hanging in right whales' mouths that are used to strain seawater for food. Until the early 1900's, right whales were heavily hunted primarily for their fatty blubber, which could be burned in oil lamps or made into soap.

2016年11月30日 · Modern whales are toothless and so capture their prey using their hallmark adaptation: baleen, a series of horny filtering combs that line the upper jaw. Baleen is the key feature that...

Where the whales tongue rubs against the baleen, the baleen is worked into a series of bristles. This inner fringe allows whales to filter large quantities of small prey from the water. Different species of baleen whales differ in the shape of the baleen and the fineness of the fringe.

Baleen whales make up one of two whale suborders within the cetacean family. The other is the toothed whale suborder which also includes all species of dolphin and porpoise. Most baleen whales are significantly larger in size when compared to the toothed whale species with the blue whale (the largest of the baleen whales) reaching lengths in ...
