Sharks are known for their fearsome reputation as predators of the sea. They are equipped with sharp teeth and powerful jaws that allow them to catch and consume their prey. However, there is an interesting fact about sharks that many people may not know: sharks are so made that they must turn on their back before snapping their victims.
This may seem like a disadvantage for sharks, as it puts them in a vulnerable position when attacking their prey. However, scientists believe that this behavior may actually be an advantage for sharks, for it allows them to conserve energy and make more efficient attacks. When sharks turn on their back, it is able to use the force of gravity to their advantage, making their attacks more powerful and precise.
なお、言い忘れたのですが、第二段落の最後の文の “the force of gravity” は「重力の力」だと少し繋がりにくいですね。文脈から考えると「遠心力」のことだとわかるかもしれません。
