ZOOL20005 Animal Structure and Function and ZOOL20006 Comparative Animal Physiology Similar?

I'm doing ZOOL20005 Animal Structure and Function this semester and was thinking about doing ZOOL20006 Comparative Animal Physiology next semester. Has anyone done both and can tell me if it's worth doing, or if they are too similar? Or even if you've only done Comparative Animal Physiology, pls let me know how it was and what sort of content you covered!

thanks guys
