Vibration playback to a 4-d old Agalychnis callidryas egg clutch. The vibrational stimulus was presented through an array of blunt metal times inserted among eggs. The clip shows a series of ten 0.5 s vibration pulses, separated by 1.5 s silent intervals, and then the beginning of a longer silent gap during which two embryos hatch from the left side of the clutch.
