Gaurdian of the Lagoon

I don't know why I titled this picture "Gaurdian of the Lagoon" (sounds formal doesn't it?), but I like the title, even though not even a week after I finished it and titled it, I learned in my world geography class was a pool of seawater that was seperated from the rest of the ocean and was filled with small forms of sea life. (I think that was the definition, I maybe off a little, but you get my drift). Sooooo.... I don't know what all that non-coastal plant life is doing there, but the name is going to stick. Oh well.
