Streamlined body is a shape that lowers the friction drag between a fluid, like air and water,...fish is such a example who have such body shape...

The streamlined body is found in fish.

- Explanation:
The term "streamlined body" refers to a body shape that allows an organism to move efficiently through a fluid, such as water or air. A streamlined body typically has a shape that minimizes resistance and drag, allowing for faster and more efficient movement.

- Fish:
Fish have a streamlined body shape that is specifically adapted for swimming in water. Their bodies are elongated and tapered at both ends, with a smooth and rounded profile. This shape allows them to move through water with minimal resistance, enabling them to swim quickly and efficiently.

- Adaptations:
Fish have several adaptations that contribute to their streamlined body shape and efficient swimming abilities:
1. Fusiform shape: The fusiform shape of a fish's body, which is tapered at both ends, helps to reduce drag and turbulence as the fish moves through the water.
2. Scales: The scales covering a fish's body are smooth and reduce friction, further minimizing resistance.
3. Fins: Fish have specialized fins, such as the dorsal fin, caudal fin (tail fin), and pectoral fins, which provide stability and control during swimming.
4. Muscle arrangement: The muscles of a fish are arranged in a way that allows for efficient swimming movements, with strong contractions and minimal energy expenditure.

- Benefits:
Having a streamlined body shape allows fish to swim faster and with less effort. This is advantageous for various reasons, such as:
1. Escape from predators: Fish can quickly evade predators by swimming away at high speeds.
2. Efficient hunting: The streamlined body shape enables fish to move swiftly and catch prey more effectively.
3. Migration: Many fish species undertake long-distance migrations, and a streamlined body shape helps them travel efficiently over long distances.

- Other examples:
While fish are the most commonly associated organisms with a streamlined body, other animals also possess similar adaptations. For example, dolphins, seals, and sharks have streamlined bodies that allow them to move efficiently through water. In the case of birds, certain species like penguins have streamlined bodies for efficient swimming underwater.

In conclusion, the streamlined body is found in fish, which have an elongated, tapered shape that reduces drag and allows for efficient swimming in water.
