Cool as it is, the title of this video is an over statement. Not all snake venoms does that. My understanding of the subject is that by example hemotoxin produced by vipers destroys red blood cells which prevents blood clotting.


You're half right: not all venoms are coagulants. You're also right that vipers have hemotoxic venom.

But vipers and their hemotoxic venom are exactly the ones that often have this coagulant effect. Venom can be hemotoxic and still be either coagulant or anticoagulant. Neither is necessarily implied.

There's lots of non-venomous snakes that have anticoagulants, too. The bites aren't especially bad or painful, they just bleed like hell.
