The Creatures of the Deep (Pond)

In class for the past 3 weeks, we have been learning about pond creatures like planaria, hydra and daphnia. We just finished our labs on them in class. The labs include the pond creatures' appearance, behavior, fun facts, habitat, food chain and a lab drawing of these pond creatures. There is  a great deal of life in a pond that you don't see until you look closer under a microscope. When you look under the microscope you will see the daphnia's one compound eye, it's intestines, and egg sacs. The daphnia jerks up and down to create a current which supplies it with air and food. When you look at the planaria you will see its two crossed eyespots in the middle of its triangle shaped head that can only detect light and dark. One third of the way down from its body tube is its mouth tube on the bottom side of the planaria. Which of the three creatures did you like best? (by Caroline)
