If we can’t even trust the Smithsonian not to lie to us, what hope is there?

The February issue of the Smithsonian magazine arrived, full of articles about origins and evolution. I immediately gravitated to the essay about komodo dragons, whose bite, as those of you who have been bitten by one know, is poisonous. In a colorful sidebar to the main article was a smaller note about the wide range of other animals that poison their victims, titled “Pick Your Poison.”

“The komodo dragon may be the newest addition to the elite corps of predators that kill with chemistry, but the venomous world is already more diverse than people realize,” it began.

The Smithsonian article ignores this distinction for sensational purposes, as the title “Pick Your Poison” suggests. But the slow loris, which is definitely not venomous,. and  it isn’t really poisonous either. Continue reading →
