lmao, not an english native speaker here. What would be, in english language, the difference between poisonous and venomous? Lifting aside the "pois" and the "ven".
Just watch the german version, where both translates to "giftig". Who cares if it needs to bite you or if you need to bite it, if it contains poison/venom just stay away from it.
It's a common mistake, so isn't a character in a movie making it realistic? Wouldn't it be out of character for many characters to have perfect English?
Aside of the obvious meme joke.
Well, language eveolves, maybe the distinction isn't that important any more. Other languages don't have it and usually you add more context to something. Also when was the last time you tried to eat an unknown animal? Or where in a situation, where you had to decide if the dangerous looking animal is only supposed to be uneatable instead of venomous?
