In a world with thousands of cool small marine animals, it was pretty dang tough choosing only 50!

(Go to your bookshelf; you'll probably recognize their names from all your favorite marine ID books.) Without further ado, here's the top 50 small marine animaIs. Is your favorite little sea creature on the list?
