Pictured above is a starburst anemone (Anthopleura sola) with fully inflated acrorhagi (the tentacles with the rounded white ends). When tidepooling in the “Low Tide” Zone, the starburst anemone is often discovered in the middle of a fight with another anemone, with its white, blunt acrorhagi inflated. As anemones fight, touching each other with their acrorhagi, the white areas of the acrorhagi become tattered. The white is a concentration of stinging cells and when touched it will slough off, to keep on stinging the enemy again and again. Eventually one anemone will move away from its neighbor in order to stop the fight.
