A Killer Whale?

 

Killer whales, also known as orcas, have a name that may make them sound especially dangerous. But with brains four times larger than human brains, killer whales are actually among the smartest creatures in the world.

The name “killer whale” is misleading. Before scientists began studying killer whales, they were known as dangerous, bloodthirsty monsters. But there is actually no record of any serious attacks by wild killer whales on humans at any point in history.

“Killer whale” is also misleading because the creatures are actually part of the family Delphinidae, meaning they are more like dolphins and porpoises than whales. Like common bottlenose dolphins, killer whales are intelligent and easy to teach, which is why you may see them doing tricks at aquariums or amusement parks.

By putting killer whales in captivity, scientists have learned a lot about them, and many people have been entertained by killer whale shows. But killer whales are at their healthiest and smartest when they remain free in the open ocean, where they travel up to 100 miles a day with their families, communicating with and teaching each other.

1. According to the passage, what is another name for killer whales?

  1. porpoises

  2. dolphins

  3. bottlenoses

  4. orcas

2. What is the name of the family that killer whales belong to?

  1. Delphiniden

  2. Dolphinidea

  3. Delphinidae

  4. Dolphinidae

3. As used in paragraph 3, the word intelligent most nearly means

  1. strange

  2. difficult

  3. smart

  4. dangerous

4. In the final paragraph, the passage says, “But killer whales are at their healthiest and smartest when they remain free in the open ocean, where they travel up to 100 miles a day with their families, communicating with and teaching each other.” From this we can understand that

  1. putting killer whales in captivity is not the best option for the creatures

  2. putting killer whales in captivity is not a problem for the creatures

  3. killer whales can learn more on their own in captivity

  4. killer whale tanks in aquariums provide as much freedom as the open ocean

5. Up to how many miles a day do wild killer whales swim with their families?

  1. 500

  2. 100

  3. 10

  4. 1000

6. This passage mostly provides

  1. facts about killer whales and their intelligence

  2. facts about how killer whales are often kept in captivity

  3. information on killer whales’ hunting habits

  4. information on how to capture and train killer whales

Whales are the largest animals in the world, and the gentlest creatures we know. Although the whale is very huge, it is not hindered at all by its size when it is in the water. Whales have tails that end like flippers. With just a gentle flick, it can propel itself forward. The skin of a whale is so smooth that it does not create any friction that can slow the whale down. A whale’s breathing hole is located on the top of its head, so it can breathe without having to completely push its head out of the water. Whales are protected from the cold seawater by body fat that is called blubber.

Whales live in the ocean but, in terms of behaviours, they are more similar to humans than fish.

They live in family groups and they even travel in groups when they have to migrate from cooler to warmer waters. The young stay with their parents for as long as fifteen years. Whales are known not to desert the ill or injured members; instead, they cradle them.

When whales are in danger, there are people who go to great lengths to help them. One such case occurred in 1988, when three young whales were trapped in the sea. It was close to winter and the sea had begun to freeze over. Whales are mammals that require oxygen from the air, so the frozen ice was a great danger to them. All they had then was a tiny hole in the ice for them to breathe through. Volunteers from all over soon turned up to help these creatures. They cut holes in the ice to provide more breathing holes for the whales. These holes would also serve as guides for the whales so that they could swim to warmer waters.

Whales can move easily in water thanks to their______.

A. size and head

B. tail and skin
