I sometimes think about just how huge humans are in comparison to most animals. Even compared to a squirrel, which is really a pretty large organism in the grand scheme of things, humans are hulking giants.
I know humans are classified as megafauna, but we're neither the smallest nor the largest animals in that group.
How many animal species currently exist where the average adult individual is more massive than the average adult human?
Sources that cite other measures of size, like height or length, might be useful, but I would expect the focus to be on mass.
Obviously, new species are being discovered all the time, and we don't have exhaustive measurements for every species, but considering how few megafauna there are, I would expect a fairly accurate estimate to be possible.
