I've always loved seahorses (who doesn't?!) and have come to love their relatives the pipefishes as well. They all have a very peaceful, quite grace about them, with eyes that seem slightly intelligent and inquisitive. I find almost all of them beautiful and elegant.
Seahorse (6 inches tall). Note the algae growing on her. Seahorses spend most of their time motionless, so this "hairy" look of algae is normal. I particularly like the little Betty Boop curl on this particular one's forehead!
Tiny (2-3 inches long) brown pipefish crawling on coral - looks a bit like a maze!
