Document Summary

Dolphins produce a variety of sounds; high frequency whistles for dolphin dolphin communication, and click and low frequency pops associated with foraging: toadfish most easily hear the pops, toadfish exposed to the 3 different dolphin sounds, male toadfish exposed to pop sounds reduced rates of calls by 50, no changes in call rates when exposed to clicks or whistles. Flight initiation distance; how close a predator can get to prey before they flee: animals farther from refuge would flee sooner than those close to refuge, animals involved in foraging, mating, or fighting take more time to flee, predator size, speed, and directness of approach also influence fleeing behaviour, armored animals not as likely to flee from predators, animals with previous experience with a predator will flee, treefrog embryos and snakes sooner than those with no experience. Approaching predators: may allow prey to gather info about predators, often done by healthy adults, approach behaviour/boldness/investigative behaviour/predator inspection behaviour, approach behaviour in gazelles.
