The row of spearheads represents the warrior who never stops fighting trying to conquer the sun back, with his family and friends (enata, or men, around the turtle´s head), prosperity (the fish hook formed by the spearheads) and freedom (the manta). The tiki symbolizes protection and the hammerhead shark is a symbol of determination and tenacity.
Marohirohi actually means "determined, with a strong character, tenacious".
