Predation is an ecological factor of almost universal importance
for the biol ogist who aims at an understanding of the habits and
structures of animals. Despite its pervasive nature opinions differ
as to what predation really is. So far it has been defined only in
negative terms; it is thought not to be par asitism, the other
great process by which one organism harms another, nor
filter-feeding, carrion-eating, or browsing. Accordingly, one could
define predation as a process by which an animal spends some effort
to locate a live prey and, in addition, spends another effort to
mutilate or kill it. Ac cording to this usage of the word a
nudibranch, for example, that feeds on hydroids would be a predator
inasmuch as it needs some time to locate col onies of its prey
which, after being located, scarcely demand more than eating, which
differs little from browsing. From the definition just proposed
consumption of the prey following its capture has been
intentionally omit ted. Indeed, an animal may be disposed of
without being eaten. Hence the biological significance of predation
may be more than to maintain nutrition al homeostasis. In fact,
predation may have something in common with the more direct forms
of competition, a facet that will be only cursorily touched upon in
this book."
