The Blue Whale has the largest measured is 2.4 meters or 8 feet in length.
The baleen whales (Mysticeti), also called whalebone whales, is one of two suborders of the Cetacea (whales, dolphins, and porpoises). They are the edentulous whales, characterized by having baleen plates for filtering food from water, rather than teeth like in the toothed whales or Odontoceti. Living species of Mysticeti have teeth only during the embryonal phase. Fossil Mysticeti had teeth before baleen evolved.
The reproductive system or genital system is a system of sex organs within an organism which work together for the purpose of reproduction. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system.[dead link] Unlike most organ systems, the sexes of differentiated species often have significant differences. These differences allow for a combination of genetic material between two individuals, which allows for the possibility of greater genetic fitness of the offspring.

Mesoplodont whales are fourteen species of whale in the genus Mesoplodon, making it the largest genus in the cetacean order. Two species were described as recently as 1991 (pygmy beaked whale) and 2002 (Perrin's beaked whale), and marine biologists predict the discovery of more species in the future. They are the most poorly known group of large mammals. The word mesoplodon comes from the Greek meso- (middle) - hopla (arms) - odon (teeth), and may be translated as 'armed with a tooth in the centre of the jaw'.
The blue whale (Balaenoptera musculus) is a marine mammal belonging to the baleen whales (Mysticeti). At 30 metres (98 ft) in length and 170 tonnes (190 short tons) or more in weight, it is the largest known animal ever to have existed.
Long and slender, the blue whale's body can be various shades of bluish-grey dorsally and somewhat lighter underneath. There are at least three distinct subspecies: B. m. musculus of the North Atlantic and North Pacific, B. m. intermedia of the Southern Ocean and B. m. brevicauda (also known as the pygmy blue whale) found in the Indian Ocean and South Pacific Ocean. B. m. indica, found in the Indian Ocean, may be another subspecies. As with other baleen whales, its diet consists almost exclusively of small crustaceans known as krill. Whale
Whale watching is the practice of observing whales and dolphins (cetaceans) in their natural habitat. Whales are watched most commonly for recreation (cf. bird watching) but the activity can also serve scientific or educational purposes. A 2009 study, prepared for IFAW, estimated that 13 million people went whale watching globally in 2008. Whale watching generated $2.1 billion per annum in tourism revenue worldwide, employing around 13,000 workers. The size and rapid growth of the industry has led to complex and continuing debates with the whaling industry about the best use of whales as a natural resource.
Organized whale watching dates back to 1950 when the Cabrillo National Monument in San Diego was declared a public venue for observing Gray Whales and the spectacle attracted 10,000 visitors in its first year. In 1955 the first water-based whale watching commenced in the same area, charging customers $1 per trip to view the whales at closer quarters. The industry spread throughout the western coast of the United States over the following decade.
The largest body part is either the largest given body part across all living and extinct organisms or the largest example of a body part within an existing species. The largest animals on the planet are not the only ones to have large body parts, with some smaller animals actually having one particularly enlarged area of the body.
As the largest animal alive, the blue whale has the largest instance of several body parts. Zoology
