What is the structure and function of fins in fishes?
Understand the Problem
The question pertains to the anatomical structure of fish fins, elaborating on various types of fins including median and paired fins, their functions, and characteristics.
Answer
Fins are structures made of membranes supported by rays and spines, used for movement, stability, and protection.
Fish fins are appendages made of membranes supported by rays and spines. They function for movement, balance, and steering. Dorsal fins can make a fish appear larger to predators. Paired fins provide stability and maneuverability.

More Information
The dorsal fin's spines can also deter predators. The symmetrical structure of fins helps maintain balance and directional control during swimming.
Tips
A common mistake is confusing fin types (median vs. paired) and their specific functions.
