How does a streamlined body support movement in aquatic animals?

A streamlined body helps aquatic animals move easily through water by reducing resistance against their movement. This shape allows water to pass smoothly around the body, making swimming faster and more efficient.

Animals that live in water, such as fish, have bodies designed for their aquatic habitat. Their streamlined shape reduces the effort required for movement, while fins and tails help them change direction, maintain balance, and control speed.

This body structure is an example of adaptation, where an organism develops features that improve its chances of survival in a particular environment. Streamlined bodies help aquatic animals find food, escape from predators, and move comfortably in their surroundings.
