Baleen whales are cetaceans classified under the parvorder Mysticeti, and consist of four extant families: Balaenidae (right whales), Balaenopteridae (rorquals), Cetotheriidae (pygmy right The baleen whales of the South Atlantic book, and Eschrichtiidae ().Balaenids are distinguished by their enlarged head and thick blubber, while rorquals and gray whales generally have a flat head, long throat pleats, and are more streamlined Class: Mammalia.

humpbacks. All About Baleen Whales - Habitat and Distribution. The baleen of the bowhead whale can be be 4 metres long. Baleen whales are grouped into four families and they range in size from the blue whale which can grow up to 33m (ft) long, to the pygmy right whale, which is m (ft) long.

Baleen whales have two blowholes (nostrils) on the top of the head and so their blows are The baleen whales of the South Atlantic book than. A new study from the University of Otago provides the “most comprehensive picture of the evolutionary history of baleen whales” to date.

Otago Geology PhD graduate Dr. Felix Marx and Professor Ewan Fordyce created a baleen whale family tree stretching back nearly 40 million years.

This family tree – the first to be directly calibrated using dated fossils – shows which whales are. Take a deep dive and learn all about baleen whales - from what they like to eat to how they care for their young.

Baleen whales are grouped into four families and they range in size from the blue whale which can grow up to 33m (ft) long, to the pygmy right whale, which is m (ft) long. Baleen whales have two blowholes (nostrils) on the top of the head and so their blows are bushier than those of toothed whales who have a single blowhole.

Baleen whales have as many as plates of baleen in their upper jaws. Whales strain seawater through the baleen, and hairs on the baleen capture fish, shrimp, and plankton.

The salt water then flows back out of the whale's mouth.

Description The baleen whales of the South Atlantic FB2

The largest baleen whales strain and eat as much as a ton of fish and plankton each day. Especially due to baleen whales specialized diets (e.g.

blue whales (Balaenoptera musculus)) and foraging strategies (such as in minke (Balaenoptera acutorostrata) or humpback whales (Megaptera.

Baleen Whales – The Gentle Giants of the Ocean. They are the largest animals on Earth, yet they live off some of the smallest. They can grow to lengths of 30 meters (90 feet), but it is the microscopic zooplankton, krill and small fish that sustains them.

patachonica),northern fin whale(B. physalus),southernfin whale(B. quoyi),south-ern humpback whale (M. novaeangliae australis), North Pacific humpback whale (M. kuzira),andNorth Atlantic humpback whale(M.n. novaeangliae). Threats Clapham et al. () provided an overall review of the threats to baleen whales.

Southern right whales migrate annually to the Península Valdés breeding ground in Argentina after spending the summer months feeding in nutrient-rich areas of the South Atlantic.

The baleen whales of the Southern Ocean include the blue whale (Balaenoptera musculus), the fin whale (Fig. 3, center-right) and the humpback (Megaptera novaeangliae).

The most numerous baleen whale is the Minke whale (Balaenoptera acutorostrata), a species that spends much of its time in the Antarctic near the edge of the sea ice. Modern baleen whales take large amounts of water containing many small creatures they eat for food into their mouths, then then squeeze the water out through their baleen, which filters and retains the creatures to then be swallowed.

This type of feeding is called suction feeding. That is a pretty big transition from teeth to baleen. Baleen whale, (suborder Mysticeti), any cetacean possessing unique epidermal modifications of the mouth called baleen, which is used to filter food from water.

Baleen whales seek out concentrations of small planktonic animals. The whales then open their mouth and take in enormous quantities of. Baleen plates often fall out soon after a whale dies and are lost, so this one “was a very major get,” says Nadine Lysiak, a biologist at the University of Massachusetts at Boston.

Minke whales were the most abundant baleen whale in the study a (coefficient of variation, CV=), followed by humpback whales, fin whales, and right whales.

The North Atlantic right whale (Eubalaena glacialis, which means "good, or true, whale of the ice") is a baleen whale, one of three right whale species belonging to the genus Eubalaena, all of which were formerly classified as a single species.

Because of their docile nature, their slow surface-skimming feeding behaviors, their tendencies to stay close to the coast, and their high blubber. The near-extinction of several species of baleen whales by commercial whaling removed these animals as functional components of marine Rowntree VJ.

Analysis of inter-annual variation in reproductive success of South Atlantic right whales (Eubalaena australis) from photo-identifications of calving females observed off Península Valdés. the American Atlantic fleet in the years The American fleet captured some sperm whales, but the prize both primarily sought was the baleen whale.

The areas hunted by the British included Davis Strait, Greenland, and the North Atlantic. The American fleet hunted there, and in the Central and South. The sei whale (/ ˈ s eɪ /, Balaenoptera borealis) is a baleen whale, the third-largest rorqual after the blue whale and the fin whale. It inhabits most oceans and adjoining seas, and prefers deep offshore waters.

It avoids polar and tropical waters and semi-enclosed bodies of water. The sei whale migrates annually from cool, subpolar waters in summer to temperate, subtropical waters in. Hunt gleaned a lot about whale reproduction studying baleen from two female North Atlantic right whales, Stumpy and Staccato, that scientists had been observing off.

Before the advent of modern technology, whalers were restricted to the smaller Baleen Whales which included the Right Whale. Today all populations of Right Whales remain endangered.

The Atlantic population is down to individuals and not growing. The North Atlantic Right Whale is on the road to extinction. Three Species of Right Whales. Blue whales in the Southern Hemisphere are generally larger than those in the Northern Hemisphere and female blues are larger than males.

The longest blue whale on record is a female measured at a South Georgia whaling station in the South Atlantic (); she was ' 17" (m) long. The heaviest blue whale was also a female hunted in the. READ: Blue Whales of Antarctica Seen Again in South Georgia After Near Extinction.

The critically-endangered North Atlantic Right Whales. It is estimated that there are only about North Atlantic right whales left, and only of these are breeding females.

Sinceonly 22 births have been recorded. Biomass and energy transfer to baleen whales in the South Atlantic sector of the Southern Ocean. Deep Sea Research Part II: Topical Studies in Oceanography, 51(): Sinclair, Michael, and G. Valdimarsson. Responsible Fisheries in the Marine Ecosystem.

Baleen Whales Humpback Whales (Megaptera novaengliae). The Humpback Whale is very common in the Gulf of Maine and has been seen as close as ½ mile off the shore line. The world population of Humpback Whales, which are found in almost all oceans, is estimated to be fewer t.

A North Atlantic right whale rests at the ocean’s surface. With an estimated reproductive females remaining, the species could be unable to reproduce naturally in 20 years.Baleen whales are an important group of predators on Antarctic krill in the Southern Ocean.

During the CCAMLR Survey to estimate the biomass and distribution of Antarctic krill, International Whaling Commission observers carried out a visual line transect survey to estimate the number of baleen whales occurring in the survey area.

This paper reviews techniques used to estimate krill.North Atlantic right whales are one of the most endangered large whale species in the world. Hundreds of years of commercial whaling decimated the species by the early s. The species got its name as the “right” whale to hunt: these animals swim slowly close to shore and are so blubber-rich they float when dead.

They have a stocky, black body, no dorsal fin and bumpy patches of rough.
