Re: Pure predation

Are there examples of snakes which AFAIK are pure predators eating dead
animals?  The egg eating snake of Africa might be an example of a pure
predator altho all eggs are not fertilized, so ? alive.  Snakes that
exclusively prey on other snakes probably take only live prey.  Purely
arboreal snakes would have a hard time finding dead prey altho I would
dislike the word always and never in certain contexts like this.  I could
never get any of my snakes to take dead prey altho I read where others used
thawed prey.  I imagine there are also spiders which take only live prey,
but I cannot state this for certain or give you a reference.  AFAIK snakes
and spiders are purely carnivorous.
