Description: Having a head leads naturally to the development of bilateral symmetry. And it also helps you build streamlined fins if you're a fish, aerodynamic wings if you're a bird, or well coordinated legs for running if you're a fox. But, what does this all have to do with evolution? Turns out, biologists can use these various body symmetries

I was getting bored and, I think, being a real pest. I remember Brando coming and sitting on the bed and cutting out the most exquisite paper fish, with detailed scales and fins. Then he took a hotel pen and a piece of string and made a fishing pole.

Not Human Limbs

Distinguish between 'dorsal fin' (top), 'pectoral fins' (sides), and others.

Stability

While important, vehicle fins are not always prominent or easily noticed.

Not Always Visible

Fins in aquatic sports are worn to increase swimming efficiency underwater.

Diving Gear

These fins are artificial equipment, not natural parts of an organism.
