Humpback Whales

The humpback whale, like all animals, is made up of eukaryotic cells. Eukaryotic cells have a nucleus and other membrane-bound organelles, unlike prokaryotic cells which lack a nucleus.

Biotic factors that humpback whales might encounter in their ecosystem include prey such as krill and small fish, predators like killer whales, symbiotic organisms like barnacles, and other marine mammals for competition or communication.

Humpback whales typically breed in warm tropical waters near the equator. The main breeding grounds for North Pacific humpback whales are in Hawaii, while those for North Atlantic humpback whales are in the Caribbean. During breeding season, males compete for the attention of females by singing complex songs.

Humpback whales primarily feed on small fish and krill. They can be found feeding in cold, nutrient-rich waters such as the Antarctic Ocean and areas with upwelling currents like the Gulf of Maine. They use various feeding techniques, including bubble-net feeding and lunge feeding, to capture their prey.

Humpback whales' main predators are killer whales (orcas). Sharks like great whites and tiger sharks may also pose a threat to humpback whales, particularly calves and weakened individuals. Other potential threats include humans through activities like hunting and entanglement in fishing gear.

The scientific name of the humpback whale, Megaptera novaeangliae, means "big-winged New Englander." It refers to the whale's large pectoral fins, or flippers, that can grow up to one-third of its body length and its frequent sightings off the coast of New England.

The humpback is a predator, taking krill and small schooling fish, such as herring, salmon, capelin and sand lance as well as mackerel, pollock and haddock in the North Atlantic. Krill and copepods have been recorded from Australian and Antarctic waters. Humpbacks hunt by direct attack or by stunning prey by hitting the water with pectoral fins or flukes.

a blue whale can weigh up to 150 tons ( 136,000 kg ) .

Female humpback whales typically breed every two or three years. The gestation period is 11.5 months. Some females have been known to breed in two consecutive years. The peak months for birth are January, February, July, and August. There is usually a 1-2 year period between humpback births.

Because of my past experiances seeing humpback whales on tv and that I've never seen 2 baby whales next to one mother, I would say one. They also give birth underwater, so that means it would be hard to get two calfs to surface.

Barnacles are actually very helpful to whales. The relationship that they have is mutualism. They attach on to them and they eat the algae and the other harmful things on them. The whales don't mind the barnacles because the whale acually benefits off the barnacles. Barnacles are benefited because they eat the things that are on the whale

No, the humpback is the fifth largest. Largest is the blue at 90 plus, finback is next to 82', right whale to 60' and sperm to 60' approximately.

This information may change soon online as there is a large female seen in Hawaiian waters who is 63 feet long. She is approximately 40 years old.

Big enough to fit a lot of seals, sharks, or humans, that much is true.

But it only feeds on small creatures, since it's a filter-feeder.

Humpbacks are gulpers, taking in as much a 1 ton of fish per day. They eat herring (their favorite) capelin, scad, sardines, needle fish, sand lance, small salmon, squid, and krill. Their stomachs are three chambered to break down the nutrition more slowly and thereby using every bit for their body's needs. The size of their stomachs would depend on the size of the whale. First and second chambers can hold well over 200 gallons and 1 ton of krill. Some cetaceans (grey whale) eat sand and stones to aid their digestion by grinding food (like birds). Others, the vertebrae of their prey does this for them. RA

A big blue whale can be 100 feet long and weigh up to 150 tons. That's as large as a Boeing jet.

Adult Humpback Whales range in length from 12 to 16 metres (39 to 52 ft) and weigh approximately 36,000 kilograms (79,000 lb (35 tons)

The key ways is to reduce human activity that effects the humpback whale directly and indirectly. Human activity includes, Bycatch of their food, Whaling for their blubber, pollution, ship collision and whale watch effects. These are their only threats and all of them are human activities, so it's preventable. A good way to start is to raise money for a campaign or a organisation that directly tries to save the whale.

The surplus amount of blubber and warmblooded nature, and the huge amount of fish that lives in that part of the ocean, oh i almost forgot, the fact that its large body mass and tender skin(if you will call it that) it is hard for the cold to penetrate its thick layers.

Adult Humpback whales are known to have an average lifespan of around 50 to 60 years. For decades man has hunted them extensively and hence we really do not know what their actual life expectancy is. Researchers recently discovered that a whale nearly 200 years old was captured near Alaska.

Currently in the North Pacific, there is a large female who is 64 years old, and about 63 feet long. She is well known to researchers. During whaling the largest humpback was over 90 feet long, a female, and we will never know how old she was.
