They don't have the two animals I DID dissect in school: earthworm and cat (her name was Bonham).
The highest "lifeform" my kids have dissected are owl pellets.
Lastly, I didn't know until now that bat dissection was a thing.
I didn't get to dissect mice and frogs until college. We pithed a frog and then wired the heart to a primitive ECG and measured its pulse while we dripped chemicals on it.
Someone skinned their mouse and turned it into a hand puppet.
