balaenoptera musculus family

[105] However, blue whales are not as specific in their movement patterns, and there is substantial evidence of alternative strategies, such as year-round residency, partial or differential migration, and anomalous habits such as feeding on breeding grounds. [241] The correlation between song types and genetic subdivisions is unknown, but song types are currently used as the primary method of separating blue whale populations because they are stable in shape over multiple decades for each region. Sub Order: Mysticeti. [74][132], Pygmy subspecies (B. m. brevicauda) – Madagascar population: This population is found off the Seychelles and Amirante Islands, through the Mozambique Channel to the Crozet Islands and Prince Edward Islands in the spring and summer, with a nearly continuous distribution in sub-Antarctic waters in the Indian Ocean in the summer. [150] With additional satellite tagged animals (n=10),[40] reported mean swim speeds of 108 ± 33.3 km/day, ranging 58–172 km/day. ... Family: Balaenopteridae; Population: 5,000; Trend: increasing; Size: 25-27m Weight: up to 190,000kg EDGE Score EDGE Score: 5.18 (?) The blue whale diet consists almost exclusively of euphausiids (krill). The rorquals differ from the other baleen whales in having dorsal fins, short baleen plates, and heads that are flat on top, rather than arched or … The blue whale (Balaenoptera musculus) is a marine mammal belonging to the suborder of baleen whales.It is the largest animal ever known to have existed. Family Balaenopteridae (rorquals) Blue whale— Balaenoptera musculus. in the waters off Chile. Chilean blue whales are genetically differentiated from Antarctica blue whales[289] and are unlikely to be interbreeding; however, the genetic differentiation is lesser with Eastern North Pacific blue whale, there may gene flow between hemispheres.[289]. Family BALAENOPTERIDAE (Rorquals) The rorquals, six species in all, make up the largest family of baleen whales. Balaenoptera f. A taxonomic genus within the family Balaenopteridae – the rorqual whales. A pygmy blue whale tagged off Perth Canyon, Western Australia traveled at mean speeds of 2.8 ± 2.2 km/h. Individuals are known to live for 1320 months and can grow to 190000000 g. Reproduction is viviparous and dioecious. An individual Blue whale can consume up to 4 tons of krill a day! [202] Little is known about mating behavior, or breeding and birthing areas. Lagerquist et al. Additionally, only one blue whale call type has been recorded in the Southern Ocean,[62][65][128][281] and mark-recapture data suggests movements of individuals entirely around the Antarctic. In addition, the ovaries of female blue whales form a permanent record of the number of ovulations (or perhaps pregnancies), in the form of corpora albicantia. Musculusmeans mouse in Latin. They vary in size from the 25-30 foot long minke whale to the 65-90 foot blue whale. Family – Balaenopteridae; Genus – Balaenoptera; Species – B. musculus; Habitat. [125] There has been one photograph-identification match between an individual blue whale in Iceland and Mauritania[126] and one match between an individual blue whale in the Gulf of St. Lawrence and the Azores,[126] suggesting connectivity among blue whales in the region. The blue whale diet consists almost exclusively of euphausiids (krill) except off Sri Lanka. It is primarily an open ocean species and is the largest species on Earth. Blue whales, Balaenoptera musculus (Linnaeus, 1758), like all rorquals (Family Balaenopteridae, the family that includes the blue whale, Bryde’s whale, fin whale, humpback whale, minke whale, and sei whale), are long, slender whales that are much more streamlined than other large whales.
