Check out our Daphnia magna! They're in kingdom anamalia and phylum arthropoda (insects, crustaceans, spiders, etc.). They've got a clear exoskeleton so that you can see all their internal organs, and they reproduce in quite an interesting way! They use parthenogenesis, which means that the entire species is female and they produce eggs that are already fertilized! They can make males under certain conditions, but 'tis certainly more efficient when you don't have to reproduce. They're our lab for this week. Next week, YOU are the lab, as we discuss the nervous system. Oo....foreshadowing.
