In our usual concept, the size of a shark is very big. In fact, this is a misunderstanding. There are many kinds of sharks, and there are more than 500 kinds of sharks recorded at present. These different kinds of sharks are very different, whether in appearance, size or other aspects, they are different.
For example, the whale shark is one of the larger sharks. Generally speaking, when they grow up, their body length can reach 12 meters, and some can even reach 18 meters. They are the largest sharks in the ocean. Although they are very large, their teeth are the smallest compared with other kinds of sharks, which is quite strange. Some sharks are of moderate size, while others are of smaller size. The pygmy dogfish, for example, is the smallest shark in the ocean, measuring only 20-27 centimeters in adult length, and may weigh less than a pound.
As mentioned above, there are many different species of sharks, and the size of different species of sharks varies greatly. Therefore, how old they can grow to adulthood is not necessarily, depending on the specific shark species. Although each species of shark has different body size after adulthood, there is generally a range within which their body length is within this range, and their body is not growing, sharks are adult. In terms of age, sharks generally need more than 10 years to become adults.
