Whoa. Cool photo of an earthworm dissection from Ravi, who appears to be using his blog to administer quizzes for his zoology class.
I never could bring myself to dissect an earthworm–not as a kid, not as an adult. As a student I always managed to talk my lab partner into doing it, and we’re still friends to this day. (Thanks, Annette) Hey, she was already planning to be a shrink at that point, which is kind of like med school, so she’d need to know this stuff, right?
Anyway, you can find out more than you ever wanted to know about cutting open an earthworm by following along with Ravi’s class.
