Hi Gang
After watching Blue Planet bo0th monday and last
night I think that this fine series really pointed out the need to deifne
various levels of preditation. In the segments of both sardines and herrings
there were the primary preds that scoped out the prey, porpoise, followed by
preds that weren't that smart, with birdes waiting around because they couldn't
get to the prey followed by sharks who came by the see what all the ruckes is
about and finally a baleen whale droped in for a bite.there may be more but
Ican't remember.None of these animals would be classed as anything but a pred
but it seems to me that there are several types of preditation to be
considered.
