Orcas, or killer whales, are the largest of the dolphins and one of the world’s most powerful animals feeding on meat. They feast on marine mammals such as seals, sea lions, and even whales, employing teeth that can be four inches (ten centimeters) long. They are known to grab seals right off the ice. They also eat fish, squid (鱿鱼), and seabirds.

Though they often frequent cold, coastal waters, orcas can be found from the polar regions to the Equator (赤道).

Killer whales hunt in deadly groups, family groups of up to 40 individuals. There appear to be both permanent and temporary group populations of killer whales. These different groups may hunt different animals and use different techniques to catch them. Permanent groups tend to prefer fish, while temporary groups target marine mammals. All groups use effective, cooperative hunting techniques that some are similar to the behavior of wolf packs.

Whales make a wide variety of communicative sounds, and each group has various noises that its members will recognize even at a distance. They use echolocation (回波定位) to communicate and hunt, making sounds that travel underwater until they meet objects, then reflect back, showing their location, size, and shape.

Killer whales are protective of their young, and other adolescent females often assist the mother in caring for them. Mothers give birth every three to ten years, after a 17-month pregnancy.

Killer whales are immediately recognizable by their special black-and-white coloring and are the intelligent, trainable stars of many aquarium shows. Killer whales have never been widely hunted by humans.

When Julio Diaz stepped off the subway after work one night, he was simply planning to go to his favorite local diner for a meal. But when a teenage boy approached him with a knife, Diaz knew the evening was about to take a more dramatic(巨大而突然的) turn.

The young man demanded Diaz’s wallet, and Diaz passed it over without objection(异议). But just as he turned to walk away, Diaz called, “Hey, wait a minute. You forgot something.”

The young man turned around, surprised.

“If you’re going to rob people for the rest of the night, you might as well take my coat to keep warm.”

The teenager looked at Diaz in disbelief, and asked why he would do such a thing. Diaz replied, “If you’re willing to risk your freedom for a few dollars, I guess you must really need the money.”He said he was heading out for dinner, and that he would be happy to take someone with him.

The young man decided to take Diaz up on his offer. As they were sitting at the table, the manager, dishwashers and waiters all stopped over to say hello to Diaz, and the young man was amazed at his popularity.

“Haven’t you been taught that you should be nice to everybody?”Diaz asked him.

“Yeah, but I didn’t think people actually behaved that way,” the teenager replied. Thanks to Diaz, he was beginning to see that kindness wasn’t so strange, after all.

When the bill came, Diaz told the teen that he’d have to get the check. After all, he still had Diaz’s wallet.

But the teenager put the wallet on the table without a moment’s thought, and Diaz treated him to dinner. Diaz also gave the would-be robber a $20 bill — in exchange for his knife. “I figure, you know, if you treat people right, you can only hope that they treat you right,” Diaz said.
