As we say begin to say farewell to summer I thought I would put up a video I like of starfish. They never seem to move around much. Here is a time-lapse video I found a while back (can't track down where) that is fun to watch:
Starfish facts:
- Approximately 1800 different species have been identified!- The Coscinasterias Calamaria also known as the eleven-armed sea star has an armspread that can go up to 1 foot. As the name suggests, it does have eleven arms but there are times when the number can go up to 14.
- They have two stomachs: The cardiac stomach can help the starfish to engulf food outside its body. When the cardiac stomach comes back into the body, the food in it is transferred to the pyloric stomach.
-The tube feet play an important role in helping the starfish to procure its food. The tube feet are used to open up the oysters or clams. Then the stomach is extended into the shell to pull the food inside.
- The starfish have microscopic eyes at the end of each arm; this enables the starfish to view movement and differentiate between light and dark. (Think about that the next time you go to grab one!)
- If a starfish loses an arm it can simply regenerate the missing limb.
- They don't have brains and they're not really fish (they don't have gills or fins). They are echinoderms.
- They are shaped like a star!!!!!!!

Hey- that is so crazy that you know the Mackey's! It never occurred to me that you grew up in the same town, California is so big that I never thought to ask if he would know you guys:) Javier was really excited about that- it really shows what a small world it really is! We actully live right next door to them. When we moved here last year they were the first ones that we met and really liked hanging out with, so know we just do almost everything together! They are such great people! You'll have to check Andrea's blog- it's linked on mine. It's great to hear from you!
