The fireflies were most likely to change their own flashing rhythm in response when the LED blinked almost, but not quite, at the same time as the fireflies. The males would speed up their next flash if the LED blinked just before and waited a bit longer for their next flash when the LED blinked right after.
Early this year, Spanish marine research organization Condrik Tenerife shared what may be the first recorded footage of a black seadevil anglerfish in daylight, near the ocean's surface. The toothy species, famous for its bioluminescent lure, typically spends its entire life navigating darkness thousands of feet below sea level-which lent this particular anglerfish's ascent a sort of heartwrenching magic, despite the fact that she likely made the trip due to stress or illness.
