           This week in science I dissected a Crayfish. Me and my partner Kendry split the Crayfish in half. But before we did that, we took pictures of it at different angles. After we cut it in half we moved some of the organs around inside each half. I don't know why I did it but I decided to pop its eye on the half that I had. The dorsal view of the fish basically shows the shell, eyes, and antenules. The antenules are proximal to the eyes. The fish needs these features to survive in its environment. The ventral view of the fish shows the eyes, antenules, and claws. Adaptation would be impossible without its claws because that's what it uses to fight off predators. The claws are long there for distal from the eyes. The crayfish lives in a watered environment. The crayfish have their claws that help them survive.
           I still wonder what the crayfishes brain looks like because I couldn't find it. I learned that Crayfish are like miniature lobsters. I learned that I like dissecting organisms with friends. My aha moment was when I witnessed Morayo and Melanies giant grass hopper squirt when she cut into it. The crayfish kind of reminds me of the plant investigation because if we didnt have patience on either projects, we would have messed up.
