Starfish

Today I went into lab to look at some slides under the microscope and take pictures. This is probably my favorite picture. I think starfish in general are interesting, so it was fun to be able to look at one under the microscope. I did some search on interesting facts about starfish and this is what I found.

-If a starfish is chopped into pieces, each piece can grow a whole new starfish (reproduce asexually).
-Starfish do not have eyes, but can sense light and shapes through the tip of their arms called an eyespot.
-The female starfish can produce a million eggs at one time.
-Fertilization takes place outside the body
-If an arm is lost, they can regrow it
-They have two stomachs: cardiac stomach and pyloric stomach
-They can change their gender whenever they want

That would be pretty useful if humans could grow back limbs if they were lost. Maybe someone will do some research on that to see how starfish do that, and if it is possible for humans to get that ability! (research would need to be ethical though!)
