I created the ecosphere with sand from the ocean. I also gathered shells and seaweed from the beach. I threw them all into the jar, sealed it and hoped for the best.

I am familiar with freshwater organisms, however marine are not my strength. It was a lot of fun to see these strange new species show up inside an ecosphere for me to st
