A List of Whales That Endures an Unpreferred Background in Popular Culture
List of Whales species is important for marine mammal researchers and naturalists. In most lists of whales, one or two species are typically represented by just a name. These species are usually too common or too minor to be identified as a separate species. For this reason, whale descriptions and identification should always come from fieldwork and not from hearsay or theory.
First, beaked whales (Cetacea des masturi) are a broad category of cetaceous whales. They are the third most common subspecies in the entire Cetacea family, after the northern and southern resident populations. The distribution of beaked whales is highly variable, with some species confined to coastal regions and other in the open seas. Beaked whales are also an irregularly distributed and diverse group of placenta-bearing marine placental mammals.
Two unique new species of whales have been recently discovered. The first is the Plastronectes beaked whale (Pte indicus), also known as the whistling whale, Southern Right Whale (Paguristes cadenati), and the gray or silver colored Bearcat (Arcturus carolinensis). The second is the Plastronectes neophrix (not to be confused with neophrix), also called the black-tipped whale or the long-toothed killer whale. The exact relationship between these two whales, however, is still under debate. It is likely, however, that both species share a common, broad repertoire of features, including an extended palate, a relatively large brain, small teeth, elongated snout, prominent pectoral flippers and a unique sense of hearing.
A record number of seven new species of whales has been discovered since 1970. These include the Plastronectes leptocyanidaeus ( paddlefish-platy), Plastronectes imbricidae ( paddlefish-eating dolphin), Plastronectes cetacea ( Dolphin-tipped whales), Plastronectes cephalophorini ( Dolphin-eating whales) and the fully-complex Plastronectes ciliately (winged whales). Additionally, there are two new species of whales from the Ogasawara Sea, the Humpback and the Echuca (also known as Caspian bear-killer or Balaena albir). While the latter two species are believed to be pre-miocene in origin, the former belong to the Paleocene or Eocene periods. Finally, there are two whales from the Southern Oceans, the Blue (Paguristes melanoleo), and the Hybrid (Paguristes bajacoi).
The newly-found beaked whale is considered as the third member of the cetaceous whales group in comparison to the sperm whales and the pilot whales. Its reproductive profile is considered unique among the other whale species and is represented by an elongated olfactory canal with a single broad head and prominent lateral line. Interestingly, this reproductive profile is shared by only a few cetal whales and that only a single beak is present in their brains. In addition to these distinctive characteristics, the newly-discovered beaked whale also possesses exceptionally robust limbs, a short trunk and robust flippers. Due to its great importance in taxonomic analysis, the study of the beaked whale is currently underway and promises to provide more information about whales.
Whales constitute one of the most diverse groups of marine mammals. In fact, whales are one of the only animal groups that have evolved through the evolution of thousands of years. Through the course of history, whales have inhabited various oceanic environments ranging from tropical swamps to temperate lakes and even deep oceans. Over the span of whale evolution, they have evolved into distinct species and each species has different physical characteristics, behaviors and social structures. The species of whales are among the largest and most diverse set of animal species in the entire ecosystem, making them one of the most studied animals in the world.
