"As the tide starts to cover the colonies, "scouts" move to the border and look for empty space to claim. The "warrior" anemones — which are larger and well-armed with stinging cells – provide backup by inflating their arms and slapping at enemies, sometimes from four rows back off the front lines."
If we are somehow related to those anemones, that last sentence would explain some of my former teachers! I still don't know how they managed to slap me with a ruler from that far back though!
