Fish have different personalities which change as they experience life’s highs and lows．a(chǎn)ccording to British biologists．
Researchers identified different“personalities” in their fish by observing the boldness or shyness of individuals，according to The Nature．Like people，some fish are very confident in the face of novelty(新奇事物)or conflict；while others are silent and fear．
The scientists selected particularly bold and shy rainbow trout，and tested whether they changed their outlook depending on what life threw at them．They arranged some fish to fight and others to watch to see how both the participants and observers responded to victories and defeats．Winning or losing a fight，or even watching fellow fish overcome the difficulties influenced the future behavior of the creatures studied in the lab．
The researchers made fish compete with much larger or smaller opponents．to ensure that they would win or lose their fights．These bold fish that won their fights tended to be even bolder when later presented with a novel food item；losing their fight caused them to be much more cautious．
Fish also learn by watching others．Bold fish watching a shy fish exploring a mystery object were much more nervous when later given a novelty item for themselves．
Predictably，shy fish that won a fight also gained more confidence，but surprisingly，shy fish that lost their fights also grew bolder when exploring strange new food，Sneddon said，adding that this could be due to what she calls a“desperado effect”(亡命徒效應(yīng))．
The new research suggests that animals can gradually adapt their personalities．The results echo the effects that life experience can have on human．

Scientists in Canada say big fish have almost disappeared from the world since the start of industrial（產(chǎn)業(yè)的） fishing in the 1950s. The scientists found the numbers of some kinds of large fish have dropped by ninety percent in the past fifty years.
The study took ten years. The researchers gathered records from fishing businesses and governments around the world. The magazine Nature published the findings.
The scientists say the common method called long line fishing ravages the populations of large fish. This method involves many fishing lines connected to one boat. These wires can be nearly one hundred kilometers long. They hold thousands of sharp metal hooks to catch fish.
Long line fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one hundred hooks. But long line fishing boats now might only catch one fish per hundred hooks.
The scientists say industrial fishing can destroy groups of fish much faster than in the past. The study suggests that whole populations can disappear almost completely from new fishing areas within ten to fifteen years.
Ransom Myers and Boris Worm of Dalhousie University in Nova Scotia led the study with the University of Kiel in Germany. Worm says the destruction could lead to a complete reorganization of ocean life systems. Meyers says the decreased numbers of large fish are not the only worry. He says even populations that are able to reproduce do not get the chance to live long enough to grow as big as their ancestors. He says not only are there fewer big fish, but also they are smaller than those of the past.

There are some things humans can go without. We can lose a kidney or a lung, an arm or two and still live perfectly well. But some fish put us to shame. They can get by without stomachs.
One such fish is the stout longtom. The group it belongs to carries a more appropriate name: the needlefish. All needlefish lack stomachs. Their ancestors had them, but later they were lost.
The stout longtom can reach 1.3 meters in length, and lives near the sea surface. Like all needlefish, it can jump out of the water to escape its enemies. Tropical fishermen are sometimes injured by needlefish. In 1977, a 10-year-old Hawaiian boy was killed when a needlefish jumped through his brain. The longtom eats smaller fish. It teeth are not good at cutting fish into pieces, so it swallows fish whole.
Ryan Day from Australia and his colleagues wanted to know how the longtom digests its meaty meals without a stomach, so they ran some chemical tests about the fish.
Day’s results show that the longtom can consume food without the help of a stomach. It uses a special material called trypsin that can break down proteins without acid — although the approach is less efficient than using a stomach.
Because it’s a meat-eating animal, the longtom gets a lot of protein in its food, so it can afford this slightly less efficient system for absorbing it. Two plant-eating fish that Day studies actually had higher levels of trypsin in their body, as their food was low in protein.
Day thinks that the longtom and its stomachless relatives might actually have arrived at an energy-saving solution. He says that although the stomach is critical to many kinds of animal, the organ is “a fairly expensive organ to run”. This perhaps explains why some animals have got rid of theirs.

The octopus’s（章魚）reputation as a human-killer isn’t simply an exaggeration（夸張）—it is a total myth. The octopus can indeed be a deadly hunter, but only of its natural victims. Some shellfish（殼類動物）and an occasional sick or incautious fish have reason to be frightened of this multi-armed hunter, but a person is much too large to interest even the biggest octopus. Even the largest among octopi is much smaller than most people imagine. Far from being large enough to swallow a ship, as monster octopi in movies have been known to do, the largest octopus, found on the Pacific coast, weighs around 110 pounds and grows to no more than ten feet in width.
The hard, parrot-like beak（喙）of an octopus is not used for attacking deep-sea divers, but for cutting open shellfish. Indeed, the octopus possesses such a tiny throat that it cannot swallow large pieces of meat. Instead, it feeds by pouring digestive juices into its victims, and then sucking up the soupy remains. A shellfish that finds itself in the grasp of an octopus has only a short time to live. But human beings are perfectly safe. Still, people rarely care to go close enough to these careful creatures to get a good look at them.
1.This passage is mainly about .
A．the horrors of the octopus
B．the largest octopus in the world
C．octopi and their behavior
D．the octopus’s deadly hunting method
2.It is implied but not stated in the passage that .
A．people have unreasonable fears about the octopus
B．the octopus is not interested in human beings
C．the octopus is afraid of human beings
D．the octopus is a very cruel sea animal
3.What does the underlined part “careful creatures” refer to in the last paragraph?
A．Octopi. B．Shellfish. C．Fish. D．The victims.
4.The hard beak of the octopus is used for .
A．a(chǎn)ttacking deep-sea divers B．cutting up large pieces of meat
C．cutting open its victims D．defending itself
5.From the passage, we can conclude that .
A．the octopus is not dangerous to man
B．people often fear creatures that are not dangerous to them
C．the octopus only hunts its natural victims
D．things described in movies are not to be believed
