The whale is a cetacean and marine mammal. In fact, the name "whale" is among the larger animals like the white whale and the orca. At first, the whales were considered fish, but because they have no gills and vents, indicating that the whale has lungs that are considered mammals. It's kind of mammal that the longer distance routes in migration of the planet. The blue whale has a size of 33 meters and weighs 100 tonnes. This example demonstrates the size and the size of a whale. But some species may have on whales the size of a human being. There are two groups of species of whales, toothed whales commonly called toothed whales like killer whales and sperm whales and baleen whales as beaked whales and orcas.

They are threatened because cosmetic companies have used the fat and the flesh of whales in their product. The whaling is now strictly limited, but some countries like Japan and Norway continue to hunt whales because of the economic loss that would result. Fish are one of the main resource of these two countries and the whale eat a ton, so they want to cut off being pulled more fish to eat. The whale is also consumed in these countries, which can lead to considerable demand for whale meat, and then follow the extinction of the whale.
