Bouyant Facts About Humpback Whales
), Belenville is known for his elaborate court songs and performances. Humpback whales are typically 12 to 16 meters (39 to 52 ft) long and weigh about 36 metric tons (40 short tons). The body is black on the upper surface, white below, and has about 30 wide grooves on the throat and chest. This cetacean differs from other baleen whales in having long, narrow fins that are about one-third the length of the body and are blunt at the leading edge. Humpback whales also have large patches on their heads, jaws, and bodies, each of which is attached to one or two hairs. The dorsal fin is short and placed far back on the body.
Humpback whales live along the coasts of all oceans, sometimes swimming close to shore, even in harbors and rivers. They make long migrations between polar feeding grounds in summer and tropical or subtropical breeding grounds in winter. Food consists of krill, small fish and plankton, which humpback whales push out of the water with their whalebones. Humpback whales use a unique feeding method called bubble netting, where bubbles are inhaled while swimming in a spiral under a body of water. A bubble screen confines the victim to a small area with one or more summons in the middle.
The most vocal of all whales, humpback whales make a variety of sounds, from grunts and grunts to grunts and grunts. Whales combine them to form “songs” that last from 5 to 35 minutes. Songs vary between groups of whales in different regions, and undergo gradual but distinct changes from year to year.
The humpback whale is also one of the most acrobatic cetaceans. It often breaks up, pulls its belly completely out of the water, then turns and comes back to the surface with a loud splash. When the animal begins to dive deep, it bends over on its back and moves quickly with its tail out of the water and standing on the surface of the sea.

Humpback whales were once commercially valuable, and in the early and mid-20th century their numbers were greatly reduced due to overhunting. It has been protected from commercial whaling worldwide since the mid-1960s and its population has increased dramatically. This increase in population prompted the International Union for Conservation of Nature (IUCN) to list the humpback whale’s status as endangered.

Related to other scuba divers in the family Balinopteridae, including blue whales, blue whales, and sea whales. The last part of the humpback whale’s species name is a Latin reference to colonial New England, where it was first scientifically described.

Learn all about humpback whales, the great whales – where they live, what they eat and why they don’t have teeth.
Humpback whales are the stars of the show in the world of whale watching due to the frequency with which they exhibit surface activity. They love to provoke, pushing themselves out of the water to show more of their bodies, leaping into the air and landing with a bang.
Humpback whales are 15 to 19 meters long (about the size of a bus) and weigh about 40 tons. One of their most prominent and unique features is their long and inconspicuous looking pectoral fins (flippers). They can grow to about 5 meters in length, giving them a relatively long fin compared to baleen whales.
, meaning “Great Wing of New England”. Although they look very tall and complex, scientists have discovered that they are actually very hydrodynamic and maneuverable.

Humpback whales can be found in all oceans of the world, but their greatest concentration is on the Antarctic ice shelf at 81°N latitude. Where you can usually find them depends on the temperature and time of year. In summer, they spend most of their time in high latitudes such as the Gulf of Alaska or the Gulf of Maine, and in winter they are found in warmer waters near the equator.
Humpback whales can be seen in the Shetland Islands near the southern tip of Scotland. Many species of whales migrate close to the Shetland Islands, and the best place to see them is 40-50 miles west of the islands, where they make their way to their feeding grounds during peak feeding periods in June and July. They pass together.
Yes, humpback whales have the longest migration of any mammal, especially a marine mammal. They spend summers in warm tropical waters at high latitudes and winters in cold, nutrient-rich productive waters.
Satellite studies show that humpback whales sometimes interrupt their long migrations at large seamounts called seamounts.
Best Places For Whale Watching
For example, they stop for a few days off the coast of La Perous between the islands of Réunion and Madagascar in the Indian Ocean, and continue their southward migration in the Pacific Ocean off the coast of New Caledonia. More before you give up.
It’s not known exactly what humpback whales do during these stops, but they may be feeding in areas above the water that are often full of plankton and fish.
Another theory is that male humpback whales use seamount’s acoustic properties to amplify their songs across the ocean.
Perhaps the whale can detect semonauts (which affect Earth’s geomagnetic field) using magnetic mind maps.
Amazing Humpback Whale Facts For Kids
Humpback whales are baleen whales and therefore toothless, meaning they have specialized feeding filters in their mouths. They filter their food through whalebone plates, which are made of folded bristles that grow in rows from the upper jaw.
They put large balls of water in their mouths, then push the water out with their plates, trapping the prey inside. The prey consists mainly of krill – small crustaceans and other small invertebrates, but may also include small shoals such as anchovies, sardines and mackerel.
Some humpback whales use a clever, cooperative fishing method called “bubble netting.” These whales will dive under the school of fish and then blow air bubbles as they fly. As these bubbles rise, they swirl around and trap the fish in a tight ball. The whale can then swim quickly towards the shoal and cut off a concentrated fish. This behavior often occurs in groups and is thought to be learned rather than adaptive, as some groups know how to do it and others do not.
A distinctive feature of the head is a series of ridges called tubercles. Each has sensory hairs, and it is possible that whales use these “hairs” to gauge the density of prey in the water while feeding.

It has up to 400 bullion plates that pressurize the water to expel food – often krill or fish shoals. The throat opening is about the size of a soccer ball, so only small prey can be swallowed.
Humpback whales have 14-35 grooves, called the “ventral plate”, that extend back to the navel. This allows the throat to expand significantly when seawater enters during feeding.
These fin-like fins can be broken against the surface of the water, often together when the whale is lying on its back. They are mostly white for the entire length of the animal’s body and one-third of the animal’s body.
The area between the dorsal fin and the fluke (tail) has a very strong muscle. This means that the whale is able to go below the surface and does not need to dive deep before it can “take off”.
Hawaii’s Humpback Whales Migration
As you might guess, humpback whales are named after the prominent hump on the front of their small, skinless fins. Compared to other whales and dolphins, this dorsal fin is short and compact. This pressure is placed on the skull as they arch their backs up and down in preparation for the dive.
Because they don’t have teeth to tell their age, it’s hard to know how long they can live. Some estimates put him in his 50s, while others say he could be as old as 80.
