Sea Monkeys: 14 days old

I learned that the long thing (i thought it was a tail) on the Sea Monkeys is actually POO!
I've noticed that it looks like the Sea Monkeys like to swim around upside-down. My Sea Monkeys are all different sizes so I think that some were born before than others. I hope the Sea Monkeys breed so I could have generations of them. It would be interesting to see them hatched.
Anyways, my little sister is going to bring her sea monkeys to school for her show & tell.
