In some cases observing the live animal is preferable to dissection. I have my students observe live earthworms using a biocular scope and they can see the blood running through the dorsal blood vessel of the worms. Also I have brought in live frogs, have fish in the fish tank to observe. I learned fish dissection by cleaning fish that we caught out of the lake, we always opened the stomach to see what they were eating so we could adjust the bait we used.
