Answer 2

Fish can easily swim in eater because of its streamlined body and shape.

Explanation:

A streamlined body shape provides less resistance while moving. It offers less resistance to the body when moving in air or water. Fish like dolphins, sharks and whale have a large body but they move with ease in water.

This is because they have pointed nose in the front and then a smooth bottle shape structure which reduces the friction and increase their speed.
