Category: Whale. Both sexes are estimated to reach sexual maturity between 5-15 years of age and females appear to have a calf every 2-3 years. At present, fin whales are threatened by manmade injuries, the most serious being collisions with boats. These first whales, such as Pakicetus, were typical land animals. After 11 to 12 months of gestation, a pregnant female gives birth to a single calf in tropical and subtropical areas during midwinter. Blue whales can be found in all of our planet’s oceans, except the Arctic, usually swimming alone or … Feeding occurs throughout the day at intervals of 8 to 10 minutes. There are very rough estimates for specific regions: North Atlantic - 53,000 whales; Mediterranean Sea - fewer than 10,000 whales; North Pacific – 17,000 whales; Southern Hemisphere - 38,185 whales. Recovery strategy for blue, fin, and sei whales (Balaenoptera musculus, B. physalus, and B. borealis) in Pacific Canadian waters. It is the only rorqual found commonly in the Mediterranean. Fin whales can dive as deep as 230 meters and stay submerged for around 15 minutes. Fin whales have long lives: they reach physical maturity at about 25 years, and their maximum lifespan is about 90 years. What’s life like for a fin whale? A new hybrid between a blue whale, Balaenoptera musculus, and a fin whale, b. physalus: Frequency and implications of hybridization. Canadian Journal of Zoolology 65: 253-264. Doing this enables them to dive approximately 800 feet back down into the water. 2001. Fin whales are often solitary but are sometimes found in pairs or small groups of 6-10 individuals. In Canada there is both an Atlantic and Pacific population of fin whale. Fin whales feed primarily on small invertebrates, schooling fish and squids. A whale has died after it became stranded on a Cornish beach despite rescuers desperate attempts to save the 'malnourished' titan's life. LIFE SPAN: 80 years. They do not have specific mating grounds and rely on their voices to find each other. Males and females are very similar in appearance, with females slightly longer than males.

They are able to take in up to an incredible 70 tonnes of food-rich saltwater into their extended throat and then use their baleen to sieve out the food as they expel saltwater. Since a calf is not able to suckle, the mother sprays her milk into the baby's mouth. The shape of their backs and their small pointed dorsal fins have given these whales another name, which is razorback. However, the dark coloration and the larger dorsal fin that is seen shortly after the blow distinguishes fin whales from blue whales, and the distinctive white coloration on the right lower jaw distinguishes from sei whales, which are also very rare in BC waters. Lockyer. Between 1999 and 2004, at least 6 fin whales were hit and killed around Canadian Pacific waters. The fin whale is designated as Threatened by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). The 52-hertz whale is an individual whale of unidentified species which calls at the very unusual frequency of 52 Hz.This pitch is a much higher frequency than that of the other whale species with migration patterns most closely resembling this whale's – the blue whale (10–39 Hz) or fin whale (20 Hz). However, their skulls particularly in the ear region, which is surrounded by a bony wall strongly resemble those of living whales and are unlike those of any other mammal. Speed may play a factor as vessels travelling over 14 knots have a much higher likelihood of fatally hitting cetaceans. It is believed from 1904 until 1979 at least 750,000 Fin Whales were killed due to whaling. Vancouver: Fisheries and Oceans Canada: vii + 53 [PDF], Brodie, P. F. 1993.

It is gray on the upper surface and white on the underside. Newborn calves are about 18 feet long, and weigh 4,000 to 6,000 pounds. Fin whales can expand their mouths and their throats while feeding due to the 100 or so pleats that go from the end of their bodies right to their mouths. Little is known about the breeding behaviours and areas of the fin whale. Their baleen plates are gray to bluish in color, with white fringes. They more commonly live in shelf and coastal waters, never in water that is less than a depth of 200 meters. Females reproduce every 2 or 3 years, with as many as six fetusesbeing reported, but single births are far more common.

One whale that was killed in Antarctica was discovered to be around 111 years old. While studies continue to define the average life span of killer whales in the wild, the most recent science suggests that the life spans of killer whales at SeaWorld are comparable to those in the wild. 2) Fill in the column on the table labelled ‘Lifespan to the nearest decade’ by rounding the numbers to the nearest 10. Cetacean Sightings Network is partially funded by the Government of Canada. Currently, fin whales are threatened by ship strikes. The young will consume milk that the mother’s body produces for approximately the first 8 months of life. Mating occurs in temperate, low-latitude seas during the winter, followed by an 11- to 12-month gestation period. This species is distributed throughout the globe, though it is rarely seen in tropical or icy polar seas. Fin-backed whale, Finner, Common rorqual, Herring whale, Razorback, Finback, Finback whale.

Fin whales are the fastest amongst the cetaceans and have been seen to breach completely out of the water. Marine Fisheries Review 46(4): 20-24. A fin whale is a filter feeder and hunts by swimming with its mouth open towards its prey, taking in large amounts of water as well as food. TOP SPEED. Although scientific studies have calculated the average lifespan of a whale to range between 40-70 years for non-endangered, healthy whales, the overall lifespan of a whale varies significantly depending on the whale species, its environment, habitat, and lifestyle. blue and sei whales – especially from a distance due to the extremely tall blows of all of these species. Fin whales are the most commonly struck whale world wide, though why this is the case is unclear. The pleats enable the mouth cavity during feeding to engulf water, Fin whales being filter feeders, with 350 to 400 baleen plates that they use to catch very small up to medium-sized life that is suspended in the sea. The Fin whale is the second largest animal in the world, the blue whale being the largest. Berube, M. and A. Aguilar. Scientists have determined that fin whales tend to mate in temperate waters around the winter months. It is the fastest of the rorqual group. Separate populations may exist in the Northern and Southern Hemispheres, with this species being scarce around the warmer waters of the equator. WEIGHT. Unlike other whales, fin whales are not too fond of the spotlight. The Fin Whale is a species of Rorquals from the Balaenoptera genus. They seem to be most abundant in polar and temperate areas.
