Baleen Whale

Baleen Whale1

About Baleen Whale :
The baleen whales are also known as whalebone whales or great whales. Baleen whales are characterized for having baleen plates for cleaning food from water, rather than having food with the help of teeth. This distinguishes them from the other species like cetaceans, the toothed whales. Living Mysticeti species have teeth only for the period of the embryonic phase.

Anatomy :
All baleen whales demonstrate some dissimilarity in the feature of their body shape. This body shape decreases drag and energy capability for swimming. Baleen whales are one of the largest animals. Large size helps them to protect from predators and it act as an advantage to the species that struggle for mates. As the Baleen Whale increases in size, its capability to preserve body heat also increases. This is due to a huge body core to generate metabolic heat enclosed by a comparatively smaller surface area that is the skin to give that heat to the environment. They do not have any teeth in their mouth. They do build up tooth buds in the embryonic stage, but these tooth buds vanish before birth.

Diet :
A baleen plates decide the type of prey it catches and feed on. The particular filter-feeding method of baleen whales enables them to eat low on the food chain by mainly eating zooplankton and schooling fishes. These food sources are frequently encountered in great swarms or schools. Some food may depend on food accessibility in feeding places.

Habitat :
Some baleen whales usually stay near the shore while others are marine and they wander the open seas. Some species deliver and take care of young ones in confined coastal bays and lagoons. Some species hunt along the productive continental shelf area.

Types of Baleen Whales :
There are eleven types of baleen whales alienated into four different families:

  • Eschrichtiidae: These whales are only the gray whales.
  • Balaenopoteridae: It includes humpback, blue whale and minke whales. These whales are popularly known as Rorqual whales.
  • Balaenidae: It includes the bowhead, the northern right and the southern right whales. This group is often referred to as right whales. They got this name because they were the right whale to chase for, due to their excessive amount of oil and blubber.
  • Neobalaenidae: This whale are called pygmy right. Not much information is known about the pygmy right whale, and it is occasionally included in the family of Balaenidae with the other right whales. On the other hand, it has a dorsal fin while other right whales do not.
  • Blue Whale Baleen :
    The blue whale is the biggest animal that ever lived on Earth. It is also considered as one of the loudest animal on Earth. These huge mammals eat small organisms, like plankton and krill, which they separate through baleen.

    Hump Back Baleen Whales :
    The humpback whale is generally species of baleen whale and a Rorqual whale that sings wonderful songs. It shows difficult and helpful feeding techniques. The humpback has a huge head with uneven protuberances each with a spine. Humpbacks are acrobats of the deep-sea. They always breach and slap the water.
