So sick, that is.

Fleshy starfish like this one move by thousands of tiny tube feet on their underside. It's almost as if each arm is a millipede, but the millipede legs end in suction cups. The overall effect of their locomotion is a gliding movement. Here's a good YouTube look at the tube feet underneath:

Brittle stars, skinnier starfish relatives, do move more by walking with their legs.

*cough* Sea Stars... *cough*

Always cool to think of animals who move using hydrolics in their body, thats why they look like they are convulsing.

It would be awesome to see a time lapse of a star fish regenerating.

That is SO COOL!

They use their hundreds of tiny tube feet to get around!

Oh, jenjen beat me to it!

Damn. Stupid intelligent people. I was gonna say that they moved using tiny tube feets. =(

Oh well.

I always thought they walked on two legs like Patrick in Sponge Bob.

i want to see them pop and lock it next!

I've seen them move on discovery channel episodes, its pretty cool

So my question is this: these were filmed underwater, yes? So then why isn't any of the vegetation moving with the currents?

The main place I've found starfish is tide pools. Not exactly current-filled.

But to me it looks like these starfish arent underwater at all, at least near the end.

haha with music, it looks like they're dancing

Are the two at the end getting their starfish lovin' on?

Underwater does not mean "in the wild". It's probably aquarium

Very creepy.

Hi. I made this time lapse. It was filmed outside on rocks that created something like tidal pools. Mostly just rocks covered in seaweed, barnacles, snails and other critters. Its difficult to see that the orange sea star comes about half out of water in its shot, and then goes back under again. I used a polarizer to cut glare off the water. I'm also surprised that the lighting came out so well, but it was a clear blue sky that day, so the light was steady, giving the appearance of indoor lighting. Not done in an aquarium though!
