鲨鱼的资料（英文）

How long have sharks existed?

Fossil records indicate that ancestors of modern sharks swam the seas over 400 million years ago, making them older than dinosaurs! They are considered to be the first vertebrate with a complete jaw. Throughout time sharks have changed very little.

What is an "elasmobranch"? Elasmobranchs are a closely related group of fishes, differing from bony fishes by having cartilaginous skeletons and five or more gill slits on each side of the head. In contrast, bony fishes have bony skeletons and a single gill cover. Elasmobranchs include sharks, rays, and skates.

Do sharks have bones?

No, sharks and all other fishes belonging to the class Chondrichthyes lack true bone, but rather have cartilaginous skeletons.

How long do sharks live?

While longevity data are not available for many sharks, maximum ages do vary by species. Some sharks like the smooth dogfish (Mustelus canis) may only live 16 years, while others such as the porbeagle shark, (Lamna nasus) may live as long as 46 years. Whale sharks (Rhincodon typus) the largest fish in the world may live over 100 years.

What does a shark's skin feel like?

Shark skin feels exactly like sandpaper because it is made up of tiny teeth-like structures called placoid scales, also known as dermal denticles. These scales point towards the tail and helps to reduce friction from surrounding water when the shark swims. Because of this, if someone rubbed the skin from the head towards the tail, it would feel very smooth. In the opposite direction it feels very rough like sandpaper. As the shark grows, the placoid scales do not increase in size, but rather the shark grows more scales. The silky shark (Carcharhinus falciformis) has small scales giving it a "silky" feel to the touch.

Do sharks sleep?

It was once believed that all sharks had to swim constantly in order to breathe and could not sleep for more than a few minutes at a time. Oxygen-rich water flows through the gills during movement allowing the shark to breathe. While some species of sharks do need to swim constantly, this is not true for all sharks. Some sharks such as the nurse shark have spiracles that force water across their gills allowing for stationary rest. Sharks do not sleep like humans do, but instead have active and restful periods.

翻译英语 关于鲨鱼的

鲨鱼生长缓慢。大约40%的品种是卵生。剩下的直接生出小鲨鱼（卵胎生，答者注）。一些鲨鱼会在身体内带着鲨鱼宝宝。

大多数鲨鱼阴错阳差才会咬人。他们以为人是海里的很大的动物。当太阳落山和升起时，鲨鱼开始觅食。所以此时不宜在海中游泳。每年蜜蜂、蛇和大象都会比鲨鱼杀死更多的人。现在人们捕杀鲨鱼，有的是为了运动，还有为了获取它的皮和食物（鱼翅）。世界上鲨鱼的数量在急剧减少！
