Antarctic blue whale: World’s Tallest whale

The World’s Tallest whale: The blue whale is the tallest animal on the planet. Its size is impressive, reaching up to 110 feet and weighing over 330,000 pounds. The largest whale in the world is the Antarctic blue whale. These creatures are larger than their Northern hemisphere counterparts, which grow up to 90 feet long and only 200,000 pounds. The female blue whale is bigger than the male, weighing between 6 and 8,000 pounds. Their calves are around twenty-three feet long and gain about 200 pounds a day.

Blue whales are protected under several international and U.S. laws, including the Endangered Species Act of 1973 and the Marine Mammal Protection Act of 1972. Although these laws have helped to protect the blue whales, the population is still in decline. In fact, the species is now classified as critically endangered on the IUCN Red List. The British Antarctic Survey recently led an expedition to the sub-Antarctic island of South Georgia, where they counted 55 whales. Although the population of these animals is still low, South Georgia waters remain an important feeding ground for them.

Bowhead whale: World’s Tallest whale

Bowhead whales live in the cold waters of the Bering, Beaufort, Chukchi, and Davis Straits. They are also found in eastern Greenland and Spitsbergen. In the winter, they live near the southern limit of the pack ice and migrate north once sea ice breaks. This means they are often spotted close to shore.

Bowhead whales feed on krill, shrimp-like creatures that are less than an inch long. They swim into groups and filter food through their overlapping baleen plates. Their massive bow-shaped head and baleen plates can grow up to 10 feet long.

Minke whale: World’s Tallest whale

Minke whales are among the largest mammals in the world. While they typically migrate to warmer waters at mid-latitudes, they also spend the summer season in colder waters. Because of this migration, these whales leave Icelandic waters in late September. Although the minke whale’s seasonal migration patterns are largely unknown, researchers have noted that they are frequently sighted in the same region.

Several studies have been conducted on this animal. In 1904, British zoologist Gordon R. Gray described it as a new species of “pike whale” and named it B. huttoni. It was not until the 20th century that scientists realized the true extent of the minke whale’s size.

The Humpback whale can grow up to 60 feet in length. The whales are migratory and often travel thousands of miles. They usually feed near the poles and breed in tropical or subtropical waters. Their migrations are highly visible. These whales are also known for their spectacular breaching.

Humpback whales are a favorite of whale-watchers. Although they are not a particularly shy species, they may be agitated or upset by boats. Whale-watching enthusiasts may also be able to see them swim close to shore.

Fin whales are migratory and can be found in all the world’s oceans, except for the polar ones. They have been seen all along the eastern coast of North America. Although they tend to stay in temperate waters, they may migrate to the polar regions during the winter.

The fin whale has a torpedo-like body and can reach speeds of up to 40 km/h. It is known as the greyhound of the sea and can live for up to 111 years. During the 19th century, it was an important target for commercial whalers because of its fast swimming ability. Whaling became an important industry, with commercial whalers killing over 400,000 fin whales in the Southern Hemisphere.
