Final answer:
Fish use their Lateral Line to sense movement in the water, helping them swim in large groups. The lateral line is a sense organ that runs the length of a fish's body and detects vibrations in the water.
Step-by-step explanation:
Fish use their Lateral Line to sense movement in the water. This helps them swim in large groups, so they appear to be bigger than they actually are.
The lateral line is a sense organ that runs the length of a fish's body and is used to detect vibrations in the water. It allows fish to navigate, locate prey, and avoid obstacles.
This adaptation is important for fish survival and plays a crucial role in their behavior and social interactions.
