​At night in Anilao's calm waters, microscopic plankton fills the water column, and a plethora of otherworldly creatures emerge.  Many, are tiny and in their larval stages, luring us with their alien light displays. The migration of these strange critters from the twilight zone (mesopelagic layer) to shallower depths (epipelagic layer) is believed to be the largest migration of species anywhere on our planet!
