maybe we call it rather like that and in addition say that

living_latex is liquid_latex but
liquid_latex is not always living_latex

No, liquid latex is only when it appears to be liquid, pouring over something or forming a sticky coating over it. Living latex is only for when it appears to be a living thing itself, rather than being pulled around by a character. In some cases, these can both happen, such as if it has its own head that isn't yet covering the victim's.
