Whales: The Giants of the Sea

Discover more about the world’s biggest mammals
海中巨人:鯨 , 一同來探索更多全球最大型哺乳 類動物的奧祕

"There she blows!"
That famous line from Herman Melville's famous 1851 novel, Moby Dick, evokes images of Captain Ahab and his sailors on their search for the great white whale. Today people still go in search of the great whales, hoping for a glimpse of them in their natural habitat.

A mystery 
These giant marine mammals have always fascinated humans because of their enormous size as well as their mysterious ways.

The sperm whale, for example, is an elusive creature that lives in remote waters and has rarely been tagged with long-distance tracking devices by researchers. For that reason, not much is known about these whales. Researchers have discovered that sperm whales are the largest toothed animal, reaching 18 meters, and that they have the largest brain of any animal. It is believed that while foraging they can dive to a depth of 3200 meters and stay under water for at least 90 minutes.

Squid is their favorite food, and sperm whales have been known to fight fierce battles with giant squid. Battle scars in the form of permanent squid sucker marks provide evidence of deep-sea battles.

Blue whales
Blue whales are the largest animal in the world, many weighing up to 180,000 kilograms and reaching lengths of over 30 meters. They are long and slender with a bluish-gray color and a heart that weights as much as a small car.

These sea giants are baleen whales, meaning they have a comb-like ridge on the top and bottom of their mouths where teeth are normally found. These whales take in water as they swim, and the baleen, equipped with bristles, filters the water and catches small ocean creatures called krill. These whales eat around 40 million krill per day, totaling over 3,600 kilograms.

Blue whales once numbered in the hundreds of thousands, but over-hunting  has nearly driven them to extinction; today it is believed that only a few thousand remain.

Gray whales
Gray whales are another kind of baleen whale. They typically swim along the ocean bottom, using their mouths to suck up mud and their baleen to filter their prey.

With heads usually covered in barnacles gray whales are easy to recognize and not shy, often swimming alongside boats and watching the people aboard.

Orcas
These stylish black and white mammals are probably the most easily identifiable whales in the sea. Also called "Killer whales" because of their aggressive predatory style, orcas prey on seals, sharks and even other whales. Orcas often travel, live and hunt in groups called "pods," which are somewhat similar to a pack of wolves. Killer whales can be found in every ocean around the world and have no natural predator except humans.

Whale-watching locations
Here are some of the best places to catch sight of these giant mammals:

Canada
Some of the world's best whale-watching can be done in British Columbia. Quebec, Newfoundland and Labrador, Nova Scotia, and New Brunswick, Canada. Orcas, gray whales, blue whales, sperm whales and others can all be spotted from May through October.

Hawaii
Another great location is Hawaii, where more than 6,000 humpback whales migrate to the islands' warm waters to mate and give birth. Whale-watching season runs from November through early May.

Alaska 
With a season that begins in April and almost never ends, you'll spot orcas, minke and gray whales.

Other places like Mexico, Iceland, Britain, Norway and the Arctic will also afford you once-in-a-lifetime views of these astonishing creatures of the sea.
