I'll probably never own a ven but they do fascinate me. This article Doesn't surprise me from what I read a lot of venomous creatures change or evolve their venom to suit new prey types or prey that becomes resistant to their current concoction of venom. Have a look at cone snails literally a chemical war factory.
