Predator-prey Interactions of Juvenile Toadfish, Opsanus tau.

Abstract

which we identified by their unique markings) that were attacked when embryos were present were tolerated in the nest when there were no embryos. Since none of these species are cryptic, and many of them are highly conspicuous (see 9), it is unlikely that the ability of D. albisella to perceive the fishes explains this pattern. These patterns suggest that D. albisella exhibits a threat-dependent level of aggression in which the size of the defended area around the nest varies as a function of relative threat of egg predation.
