Ultrasonic algae control Ultrasound refers to sound waves with frequencies above 22 kHz. At specific frequencies,ultrasound can control algae growth (video). Cyanobacteria use gas vesicles for buoyancy and depth regulation. During the day, algae can be found in the top layer, where they perform ph...
Similar to a Flightmare, Night Fury, and Deadly Nadder, by eating glowing algae, a Gronckle can control the intensity of its glow. It can turn its glow on bright in order to scare off other dragons who are trying to attack it. This was shown in "Fright of Passage", where Meatlug ...
