Have you seen that new documentary about fish?

Not yet, but I heard it's really interesting!

They explain how a homocercal tail helps bony fish swim better.

That sounds cool! I never knew the tail shape made such a difference.

Root Explanation

Homocercal → It is formed from "homo-" (from Greek "homos", meaning same) and "cercus" (from Greek "kerkos", meaning tail). The term describes a type of fish tail where the upper and lower lobes are of equal size, hence the 'same' tail structure.

Memory Tip

Think of 'same' ('homo-') when you picture a fish tail that is 'equal' in size on both sides.
