Good question, Dave. I don't know why all the research checked noted them as zooplankton foragers...they don't spit out the veges, do they?


IIRC it has to do with the size of particles the paddlefish gillrakers can filter. They filter out the "larger" zooplankton while the phytoplankton is typically too small to be retained and passes thru. So I guess you might say, in a round about way, they actually do spit out the veggies. smile
