Re: NFC: predator or scavenger?


Like many other animals, catfish, squawfish, bald eagles, for that matter, 
crayfish are both predator and scavenger.

BTW, sorry if I offended in my earlier remarks.  It is never my intention to 
do so.  And you are correct, this list is not the place for philosophical or 
political discussion that is unrelated to native fishes.  I will try to 
restrain my baser instincts in the future!
