This response is extremely specific, and mostly occurs only at vibrational patterns associated with predators. callidryas embryos may hatch early and fall into the water to escape predation. If faced with the vibrational cues associated with predators, A. If disturbed, the frog flashes its bright red eyes, which may startle predators and allow the frog to escape.Īlong with its visual appearance, phenotypic plasticity in hatching is another interesting feature of A.

Its bright coloration can thus be more attributed to camouflage amongst the greenery of the surrounding jungle, as well as the “startle reflex,” which it can use to dissuade predators.
