They live in waters all over the wor

4、ld, in every ocean, and even in some rivers and lakes. Sharks and long fish Unlike bony fish, sharks have no bones; their skeleton is made of cartilage (软骨 ), which is a tough, fibrous (纤维性质的 ) substance, not nearly as hard as bone. Cartilage, a strong fibrous substance, is softer than bone; our nos

5、e and ears are made of cartilage. Sharks also have no swim bladder (鳔 ) (unlike bony fish). Size There are many different species of sharks that range in size from the size of a persons hand to bigger than a bus. The Whale shark is the largest fish in the world; the basking .shark (姥 鲨 ) is the seco

6、nd largest fish. Fully-grown sharks range in size from 7 inches long, up to 50 feet long. Most sharks are intermediate in size, and are about the same size as people, 5- 7 feet long. Half of the shark species are less than 39 inches long. Variety of sharks There are about 368 different species of sh

7、arks, which are divided into 30 families. These different families of sharks are very different in the way they look, live, and eat. They have different shapes, sizes, color, fins, teeth, habitat, diet, personality, method of reproduction, and other attributes. Some types of shark are very rare and

8、some are quite common. The spiny dogfish shark (白斑角鲨 ) is the most common shark. Body shapes Sharks have a variety of body shapes. Most sharks have streamlined (流线型的 )bodies that glide easily through the water. Some bottom-dwelling sharks have flattened bodies that allow them to hide in the sand of

9、the ocean bed. Some sharks have a long body shape. The goblin shark has a large, pointed bulge (凸出 ) on its head, and its purpose is unknown. Teeth The teeth of sharks are also striking. Sharks may have up to 3,000 teeth at one time. Most sharks do not chew their food, but swallow it down whole or i

10、n large pieces. The teeth are arranged in rows; when one tooth is damaged or lost, it is replaced by another. Most sharks have about 5 rows of teeth at any time. The front set is the largest and does most of the work. Diet Sharks vary greatly in their diets, but they are all carnivores (食肉动物 ). Some

11、 eat fish, other sharks, and marine mammals; some eat shellfish from the ocean floor; and others eat tiny bits of plankton (浮游生物 ) and small animals from the water as they swim with open mouths. They eat huge amounts of these tiny animals and plants. Shark attacks When some sharks turn aggressive pr

12、ior to an attack, they arch their back and throw back their head. They also move their tail more acutely (probably in preparation for a chase). Sharks do not normally attack people, and only about 25 species of sharks are known to attack people. Sharks attack fewer than 100 people each year. Many mo

13、re people are killed by bees or lightning. The sharks that are the most dangerous to people are the great white shark, the tiger shark, and the bull shark. The bull shark is the most frequent attacker of people as it swims in very shallow waters where people swim and is a very plentiful shark. Some

14、of the other sharks that are known to have attacked people include the gray shark, blue shark, hammerhead shark, mako shark, nurse shark, lemon shark, and blacktip reef shark. Some people believe that sharks mistake people (especially people swimming on surf boards) for seals and sea lions, some of

15、their favorite foods. Occasionally, a group of sharks will attack a food source (for example, a school of fish) in a crazy fashion. They will wildly attack the food and anything in the area, even each other, sometimes wounding or eating fellow sharks. Habitat Sharks live in oceans and seas all over

16、the world, and even in some rivers and lakes, especially in warmer waters. Some sharks live near the surface, some live deep in the water, and others live on or near the ocean floor. Pelagic (远洋的 ) sharks (living in the open ocean) include the great white shark, the basking shark, etc. Benthic shark

17、s (living at the ocean floor) like the zebra horn shark usually have flattened, camouflaged (伪装的 ) bodies that let them hide in the sea bed. Some sharks even venture many miles up into the fresh water of rivers like the Mississippi in the USA and the Amazon in Brazil. The bull shark sometimes ventur

18、es into fresh water. Migration of sharks Some sharks live in relatively warm waters (hammerheads, bull sharks, and tiger sharks). Other sharks, such as the thresher, mako, basking and blue shark, live in temperate water (which is neither hot nor cold). Others, including the dogfish, Greenland, and g

19、oblin, live in cool waters. Some sharks stay in the same region in their entire lives while others travel across oceans. There are three different types of sharks when it comes to migratory (迁移的 ) patterns: Local sharks, coastal pelagic sharks, and highly pelagic sharks. Local sharks do not migrate,

20、 and range only about a hundred miles from their habitat, coastal pelagic sharks can migrate over 1,000 miles (1,600 km), while highly pelagic sharks migrate across oceans. Evolution of sharks Sharks have existed for over 350 million years. They evolved over 100 million years before the dinosaurs di

21、d. This was long before people evolved. Most fossil evidence of early sharks is from fossilized teeth and a few skin impressions. Cladodonts, primitive sharks, had double-pointed teeth, were up to 3 feet long fish-eaters and lived about 400 million years ago. Megalodon was an ancient, meat-eating sh

22、ark, living between 25 -1.6 million years ago; it is extinct. It was over 40 feet long, but this is only an estimate from fossil teeth that have been found.
