True Facts About Sea Stars

What do you know about sea stars? Well, let's see. They used to be called starfish, but we changed that because they aren't fish. And if they lose an arm, they can grow it back. That's pretty much it. But Ze Frank knows a whole lot of interesting things about sea stars, and as always, he finds the most entertaining way to tell us about them. Spongebob Squarepants' best friend Patrick is a sea star that walks upright on two limbs, but real sea stars have several ways of walking, all of which are pretty creepy. They have feet coming out of their arms and an eye where a hand should be! If you think that's weird, wait until you see how they eat. And when you think it can't get any weirder, Ze looks at some sea star relatives which all have their own weird anatomy, defense mechanisms, and eating methods. Oh yeah, and to raise the squick factor, they have various reproductive strategies, too.  

After watching this video, I honestly wonder how science fiction screenwriters can possibly think that it's feasible for alien life to resemble humans at all. There are just too many other ways of doing life. Then again, it would be expensive if not impossible to get sea creatures to memorize lines.
