sea gardens

i can't watch this Sea Garden video clip yet, but i think it may help explain the page you're looking at now. here is the description...

Sea Gardens
This video clip begins by showing a variety of creatures moving gently in the water. Green feather duster worms and seaweed sway with the current. Next, we see a closer view of white tunicates, with their air intake and discharge syphons visible, and what might be an orangish-colored sponge. The video again shows feather duster worms, before it pans to a closeup of a tunicate rocking gently with the current.
