Latin-dictionary.net gives this for animans: animate/living being/organism (not man), creature
Wiktionary: A living thing or creature, an animal (as opposed to plants; as opposed to a man)
I'm satisfied as to the Latin. I will tentatively leave in the reference to Menoeceus, but I'm unsure that Greek treats ζωή like Latin treats animans. If I cannot come down to something more certain I will change the note so that it refers to the problem without making a definite conclusion.
