we used live specimens for bio lab. the frog we knew we had to kill:
but the goldfish we weren't sure, but we hoped not. but then our prof immediately reassured us that we werent going to harm the goldfish. whew. haha all we had to do was put it on a petri dish and make sure its gills are wet while we examine its tail fin under the miscroscope. most of our fish were feisty, jumping around, that it took a while before our group managed to focus ours under the miscroscope...blood flow of the fin. coooool.
unfortunately, some goldfish didnt make it. some died before lab class even started. (21 gun salute)
