Did you know that some fish have a small opening called a spiracle behind their eyes?

Really? I had no idea they had that feature!

Yeah, it helps them breathe while they stay still in the water.

That's fascinating! Nature has such cool adaptations.

Root Explanation

Spiracle → It is formed from "spira" (from Latin, meaning to breathe or to blow) and the suffix "-cle" (indicating a small or diminutive form). The word "spiracle" refers to a small opening or hole through which air can enter or exit, particularly in the context of breathing.

Memory Tip

Think of 'breathing' ('spira') through a 'small opening' ('-cle') — that's why a spiracle is a small hole for air.
