They vary in size from the 25-30 foot long minke whale to the 65-90 foot blue whale. , Blue whales maximize the intake of energy by increasing the number of lunges they make during a dive while targeting dense krill patches. The blue whale was not hunted by Yankee whalers because of its speed and power, so the whalers went … Sei whale—Balaenoptera borealis. Blue Whales :: MarineBio Video Library :: Blue whale song 1 ~ Blue whale song 2 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. Bryde's whale—Balaenoptera brydei and/or edeni. IUCN (2015) The IUCN Red List of Threatened Species. This genus is known in the fossil records from the Neogene to the Quaternary (age range: from 13.65 million years ago to the present). Fish and copepods (tiny crustaceans) may occasionally be part of the blue wha…  The blue whale’s two blowholes (the analogue of human nostrils) create a tall, columnar spray, which can be seen 30–40 ft (9–12 m) above the water’s surface. Major feeding grounds have been identified in the South Taranaki Bight between the North and South Islands, along the east coast of Northland (North Island), and off the east and west coasts of the South Island and the Hauraki Gulf.  Acoustic data suggests that some individuals may remain on their feeding grounds year-round.. They grow to be about 30 meters long.  Blue whale takes peaked in 1931 when over 29,000 blue whales were killed.  The estimate of pygmy blue whale off New Zealand from mark-recapture data is 718 (95% CI=279-1926, SD=433). Other accidental or opportunistic consumption of copepods and amphipods have been documented. Till the dawn of the twentieth century, … It is primarily an open ocean species and is the largest species on Earth. The blue whale finds a school of krill, and opens its mouth engulfing the entire school of krill. Manage 1(1): 41-51. Balaenoptera musculus. Version 2015-4. Antarctic subspecies (B. m. intermedia): Acoustic recordings indicate that this population is distributed around Antarctica and south of the Antarctic Convergence Zone in the summer, and then move into mid- and low-latitude habitats in fall and winter.  reported mean swim speed using only high-quality satellite locations as 2.55 ± 1.43 mph (4.1 ± 2.3 km/h) from 11 tagged blue whales.  Little is known about the population trends outside of the Gulf of St. Lawrence area.  Large-scale takes did not begin until 1864, when the Norwegian Svend Foyn invented the exploding harpoon gun and by using them with steam and diesel-powered ships. Balaenoptera f. A taxonomic genus within the family Balaenopteridae – the rorqual whales. , At least seven blue whale song types have been shifting linearly downward in tonal frequency over time, though at different rates.. In 1984, a female hybrid between a fin and a blue whale was caught by whalers off northwestern Spain. Identification. Sightings in the Gulf of St. Lawrence peak late August-early September and tagging suggests they migrate as far south as the Mid-Atlantic Bight coastal from Delaware to North Carolina and South Carolina. , Roughly 5,728 blue whales from the Chilean subspecies were killed by whalers in the Southeast Pacific, 4,288 off Chile. It was previously thought that blue whales in the North Pacific belonged to at least five separate populations; however, evidence from movement data derived from satellite tags, photograph-identification, and acoustic data supports two populations in the North Pacific—the Eastern and Central and Western North Pacific populations, with divisions according to acoustic calls being estimated by Monnahan et al.. Balaenoptera musculus ( Linnaeus, 1758) Edit —Blue Whale Balaena musculus Linnaeus, 1758 p Edit.76; Type locality- Fifth of Forth , Scotland Edit.. Physalus sibbaldii Gray, 1847 p.92; Type locality- Coast of Yorkshire , England Edit. in the waters off Chile. Balaenoptera musculus are classified in the family of cetaceans.  However, the Sri Lanka call has not been detected west of Sri Lanka, and there is another call type in the western North Indian Ocean, off Oman and north-western Madagascar, termed the Oman call suggesting a central Indian Ocean population. The greatest dive depth reported from tagged blue whales was 315 meters. Overview; Conservation Attention; Threats; About.

Balaenoptera musculus: Author: Linnaeus 1758: Standard reference: Perrin, W.F., Wursig, B. and Thewissen J.G.M. Constant, P. (2007) Marine Life of the Galapagos. Because of the high cost of lunge feeding, it has been estimated that blue whales must target densities greater than 100 krill/m3. Free and Open Access to Biodiversity Data. , Pygmy subspecies (B. m. brevicauda) – Eastern Australia/New Zealand population: Data from strandings, sightings, and acoustic detections suggest that this population is present in New Zealand waters nearly year-round. These range in size from the relatively small minke whale, about 8-10 m in length, to the giant blue whale, at 20 - 28 m length and almost 200,000 kg weight. One surfaced right next to the boat and his exhale sprayed us all. Blue whale vocalizations are among the loudest and lowest frequency sounds made by any animal.  The valid fossil species of Balaenoptera are: M. Bisconti.  There is no abundance estimate for overall pygmy blue whale abundance, which includes the Madagascar population, Western Australia/Indonesia population, and Eastern Australia/New Zealand population.   Pygmy blue whales typically remain north of 52°S, except on rare occasions, e.g. Balaenopteridae (Family) Balaenoptera (Genus) Balaenoptera musculus (Species) Status. Global Biodiversity Information Facility. , Data from individual satellite tagged Eastern North Pacific blue whales suggest leisurely traveling rates of 4 knots, or 4.6 mph (7.41 km/h), with a minimum average speed of 1.55 ± 1.68 mph (2.49 ± 2.7 km/h). Species Parent. Kingdom: Animalia.  This monophyletic clade is nested in Cetartiodactyla, which includes the even-toed ungulates. There are regular reports of much faster migration speeds and rapid sustained bursts of speeds; notably their swimming speeds were too fast for whalers until the modern era of whaling introduced steam-powered boats and explosive-tipped harpoons. Molecular analyses of the whale showed that it was a hybrid between a female blue whale and a male fin whale, and that the fetus had a blue whale father. , The pygmy blue whale subspecies, B. m. brevicauda, has three populations corresponding with acoustic populations, including a Madagascar population, Eastern Australia/New Zealand population, and Western Australia/Indonesia population. The Blue Whale Balaenoptera musculus can take in 60 to 70 tons of water with one gulp. The biggest blue whale found was 190 tons and measured 98 feet long. Blue whales were initially tough to hunt because of their size and speed. The International Whaling Commission banned all hunting of blue whales in 1966 and gave them worldwide protection. The International Whaling Commission catch database estimates that 382,595 blue whales were caught between 1868 and 1978. Family: Balaenopteridae.

They filter feed on krill and other small crustaceans and ocean creatures.  Blue whale anatomy, specifically a small testis-to-body weight ratio and documented visual observations of a second male joining the traveling pair, suggest a polygynous, antagonistic male-male competition strategy. The Diver's guide to Fishes, Whales, Dolphins and marine Invertebrates, 307 pp. , Using the number of earwax lamina deposited in the earplug and development of sexual organs from dead whales, it has been determined blue whales reach sexual maturity at about 10 years old and at an average length of 23.5 m for female Antarctic blue whales.
