One of their most noticeable and distinctive features are their long and ungainly-looking pectoral fins (flippers). These can grow to nearly 5 metres long, making them relatively the longest flippers of any baleen whale.<\/p>\n<p>This feature is related in their\u00a0Latin name, <i>Megaptera novaeangliae<\/i>, which means \u201cbig wing of New England.\u201d Although they may look overly long and cumbersome scientists have found that they are actually vey hydrodynamic and well adapted for manoeuvrability.<\/p>\n<section class=\"&quot;highlight\"><div class=\"&quot;highlight__content\" editor-content=\"\"> <ul><li><strong><a href=\"&quot;https:\/\/www.discoverwildlife.com\/animal-facts\/marine-animals\/how-did-whales-get-big\/&quot;\">How did whales get so big?<\/a><\/strong><\/li>\n<li><strong><a href=\"&quot;https:\/\/www.discoverwildlife.com\/animal-facts\/why-whales-have-blowholes\/&quot;\">Why whales have blowholes<\/a><\/strong><\/li>\n<li><strong><a href=\"&quot;https:\/\/www.discoverwildlife.com\/animal-facts\/why-whales-and-dolphins-dont-suffer-from-the-bends\/&quot;\">Why whales and dolphins don\u2019t suffer from the bends<\/a><\/strong><\/li>\n<\/ul><p> <\/p><\/div> <\/section><h2 class=\"&quot;listicle__title\" heading-3=\"\">Where do humpback whales live?<\/h2>\n<p>Humpback whales can be found in every ocean in the world, but are most concentrated in a band running from the Antarctic ice edge to 81\u00b0 N latitude. Where they can be commonly fund also depends on the temperature and the time of year. In the summer\u00a0many spend their time in high-latitude feeding areas such as the Gulf of Alaska or the Gulf of Maine, then in the winter they can be found in the warmer waters near to the equator .<\/p>\n<h2>Can you see humpback whales in the UK?<\/h2>\n<p>Humpbacks can be spotted near the southern tip of Shetland, Scotland. Many whale species migrate near the Shetland islands, and the best place to see them is 40-50 miles west of the islands where they pass on their way to visit feeding grounds, with June and July being peak periods.<\/p>\n<h2>Do humpback whales migrate?<\/h2>\n<p>Yes humpbacks have one of the longest migrations of any mammal, particularly a marine mammal. They spend their summers feeding in cold nutrient-rich productive waters at high latitudes and winters in warmer tropical waters.<\/p>\n<h3>Do humpbacks take breaks on their migrations?<\/h3>\n<p>Satellite-tracking studies have shown that humpback whales sometimes break their long migrations at giant underwater mountains, called seamounts.<\/p>\n<p>For example, they pause for a few days at La P\u00e9rouse seamount between the Indian Ocean islands of R\u00e9union and Madagascar, and in the Pacific, off New Caledonia, they hang around seamounts for a week or more before continuing their southward migration.<\/p>\n<p>It\u2019s not known for sure what humpbacks get up to during these stopovers, but they may feed in the waters above seamounts, which are often thick with plankton and fish.<\/p>\n<p>They may also congregate here to mate, using the huge geographical features as meeting points.<\/p>\n<p>Another theory is that male humpbacks use the acoustic properties of seamounts to amplify their songs through the ocean.<\/p>\n<p>Perhaps the whales locate the seamounts (which influence the Earth\u2019s geomagnetic field) by means of magnetic mental maps.<\/p>\n<p>Helen Scales<\/p>\n<h2 class=\"&quot;listicle__title\" heading-3=\"\"\/>\n<h2>Do humpback whales have teeth?<\/h2>\n<p>Humpbacks are baleen whales and therefore are devoid of teeth, which means that they have a specialised filter feeding systems inside their mouths instead. They filter their food through baleen plates, which are made up of fringed brushes which grow in rows from the upper jaw.<\/p>\n<h2>What and how do humpback whales eat?<\/h2>\n<p>They take huge gulps of water into their mouths, then push the water out through the plates, trapping their prey inside. This prey is mainly made up of krill \u2013 small crustaceans, as well as other small invertebrates, but may also include small schooling fishes such as anchovies, sardines, and mackerel.<\/p>\n<p>Some humpback whales use an ingenious cooperative method to trap fish called \u2018bubble netting\u2019. These whales will dive below a school of fish then spiral back upwards blowing air bubbles as they go. As these bubbles rise they disorientate and trap the fish into a tight ball. The whales can then swim quickly upwards into the shoal and gulp down a concentrated mouthful of fish. This behaviour is often performed in groups, and is thought to be learned rather than instinctive, as some groups know how to do it and others don\u2019t.<\/p>\n<iframe title=\"&quot;Humpback\" whales=\"\" feeding=\"\" on=\"\" billions=\"\" of=\"\" krill=\"\" deep=\"\" into=\"\" the=\"\" wild=\"\" bbc=\"\" earth=\"\" width=\"&quot;200&quot;\" height=\"&quot;113&quot;\" src=\"&quot;https:\/\/www.youtube.com\/embed\/1_BqC9IIuKU?feature=oembed&quot;\" frameborder=\"&quot;0&quot;\" allow=\"&quot;accelerometer;\" autoplay=\"\" clipboard-write=\"\" encrypted-media=\"\" gyroscope=\"\" picture-in-picture=\"\" web-share=\"\" allowfullscreen=\"\"\/>\n<h2>Identifying features of the humpback<\/h2>\n<h3>Tubercles<\/h3>\n<p>A prominent feature of the head is a series of bumps known as tubercles. Each one has a sensory hair, and it is possible that the whale uses these \u2018whiskers\u2019 to judge prey density in the water during bouts of feeding.<\/p>\n<h3>Upper jaw<\/h3>\n<p>This contains up to 400 baleen plates, which strain out the water to leave the food \u2013 often krill or schooling fish. The throat opening is merely the size of a football, so only small prey can be consumed.<\/p>\n<h3>Throat grooves<\/h3>\n<p>Humpbacks have 14\u201335 grooves, known as \u2018ventral pleats\u2019, that extend back to the navel. These allow the throat to expand massively as sea water rushes in during feeding.<\/p>\n<h3>Pectoral fins<\/h3>\n<p>These wing-like fins may be smashed against the water\u2019s surface, often together, while the whale is lying on its back. They are largely white on the underside and a third of the animal\u2019s total body length.<\/p>\n<h3>Tail stock<\/h3>\n<p>The region between the dorsal fin and fluke (tail) houses a phenomenally powerful muscle. This means that the whale is capable of breaching from just below the surface, and doesn\u2019t need to dive deep beforehand to get a \u2018running start\u2019.<\/p>\n<p>Rob Lott is a policy manager with WDC<\/p>\n<hr\/><h2 class=\"&quot;listicle__title\" heading-3=\"\">Why are they called humpback?<\/h2>\n<p>Humpback whales are named, predictably, after an obvious hump in front of their small dorsal fin. Compared to those of other whales and dolphins, this dorsal fin is small and stubby. This hump is emphasised when they raise and bend their backs in preparation for a dive.<\/p>\n<hr\/><h2>How long do humpback whales live for?<\/h2>\n<p>As they don\u2019t have teeth which could be used to estimate their age, it is hard to know how long they could live for. Some estimates say that they have a lifespan of approximately 50 years, whilst others say it could be up to 80.<\/p>\n<hr\/><h2>How do humpback whales communicate?<\/h2>\n<p>Humpback whales are well known for their haunting, evocative calls or \u2018songs\u2019. These complex sequences of moans, howls, and cries can last for hours and travel vast distances through the ocean.<\/p>\n<p>The exact function of humpback song\u2019s is not known, but there are many theories.<\/p>\n<p>As it is the male that produces the long complex songs (females have shorter vocalisations), and these are produced during the breeding season, it is speculated that they may function to attract females. It could also act as a challenge to other males. Yet another theory is that it has an ecolocative function, acting as a sonar, so that the whales can \u2018see\u2019 and navigate around their environment.<\/p>\n<p>Humpbacks also use grunts, groans, and snorts to communicate with one another, and calfs are known to \u2018whisper\u2019 to their mothers, using low tones that can only be heard from short distance away. This may help them to avoid predators and big males.

Before these can begin however, the whales must first congregate in the warm equatorial breeding waters, often travelling thousands of miles from their summer feeding grounds to find a mate.<\/p>\n<p>Once they arrive the males need to earn the right to mate with a female, and this involves often fierce competition. Unrelated males will group together to tail females and will fight each other around her, breaching, tail-slapping, and charging at one another. In doing so they hope to impress the female with their dominance and strength. Most of this fighting is for show however, and it is rare that they will cause each other serious physical harm.<\/p>\n<p>Singing also plays a part in reproduction. It is thought that males will use song to attract the female, as well as to show dominance. It may also have an important role in inducing oestrus in females.<\/p>\n<p>Once mating has occurred, the gestation period for female whales is 11.5 months. Once born, the calves are between\u00a03 and 4.5 m long and weigh up to a ton.<\/p>\n<h2>Are humpback whales dangerous?<\/h2>\n<p>Humpback whales are by nature mostly gentle and non-aggressive animals, so it is very unlikely for them to do any harm to a human. They are however very large and curious and will sometimes approach boats.<\/p>\n<p>Due to their acrobatic tendencies its is possible for them to breach and strike boats, and there was a case in 2015 of a Canadian woman who was killed when a breaching humpback whale landed on the snorkelling tour boat she was on. \u00a0This is however extremely rare as humpbacks tend to be aware of their surroundings and avoid direct contact with boats and swimming humans.<\/p>\n<p>\u00a0<\/p>\n<h2 class=\"&quot;listicle__title\" heading-3=\"\">Are humpback whales at risk of extinction?<\/h2>\n<\/div>\n<p>Intensive hunting over centuries by the whaling industry severely reduced humpback whale populations, such that the population of humpbacks in the western South Atlantic dropped to only about 450 individuals. It is estimated that at least 300 000 individuals were killed worldwide.<\/p>\n<div class=\"&quot;image-handler__container\" image-handler__container--aspect=\"\" style=\"&quot;padding-bottom:\"
