Final answer:

Ray-finned fish have thin, flexible fins controlled by body muscles, while lobe-finned fish have stronger, fleshy fins supported by bones.


Explanation:

Ray-finned fish have thin fins consisting of webs of skin over flexible bony rays, lacking muscle and controlled by muscles in the body wall. These fins are efficient for maneuvering and swimming. In contrast, lobe-finned fish have fleshy fins supported by bone, providing more strength for navigating and propelling through water.
