Abstract
ABSTRACT: The large canine teeth in Meiacanthus atrodorsalis impart a toxic bite
which causes this animal to be rejected as a prey item by several piscivorous fishes.
Two morphologically and behaviorally similar species, Runula laudandus and Besenitts
bicolor, may enjoy predator protection through Batesian mimicry and, for the
former species, greater feeding efficiency through aggressive mimicry. A limited
number of experiments indicate that the predator, Bpinephaltts merra, may learn to
avoid Meiacanthus atrodorsalis and its mimics.
