We went to the Museum today w/one of our homeschool groups. It was a major success and the kids had a great time. :) So did I. I like learning about sharks & think they are fascinating creatures. Our knowledge of them is still pretty limited, so it was fun to learn some new things. For example, they don't all have to move all the time to get oxygen. Their gills do a good job of that w/o needing to move constantly. They have more gills than other fish for that reason. Some lay eggs, some lay eggs inside themselves which hatch inside & leave momma as a live birth & some do live births! How crazy is that!
