The word hippokampos comes from ancient Greece, to break it down... hippos meaning "horse" and kampos meaning "sea monster".
Seahorses hold a gentle strength and serenity. They are graceful, calm and mild-mannered creatures. They are seemingly content to roam the seas. Their bodies are geared for wandering type motion - not for speed.
Thus, they are symbolic of patience, contentment, friendliness and protection. Like the seahorse we sometimes need to allow ourselves to be gently nudged in the right direction by the flow of the current around us. When you see the way to move forward, anchor yourself and stay focused on your goals.
