Did you know that a holothurian is actually a type of sea cucumber?

Really? I had no idea what that was until now!

Yeah, they're quite interesting creatures that live on the ocean floor.

Root Explanation

Holothurian → It is derived from the Greek word "holothourion" (ὁλοθούριον), which is a combination of "holos" (ὅλος, meaning whole or entire) and "thura" (θύρα, meaning door or opening). The term refers to a type of marine animal known as sea cucumbers, which have a soft, elongated body that can be seen as a whole or entire organism with openings for feeding and respiration.

Memory Tip

Think of 'whole' ('holos') to remember that a holothurian is a complete marine creature with openings for its functions.
