100 Mind-Blowing Communicate Facts
Herring fish communicate by using flatulence.
Giraffes hum to communicate with each other. It’s thought that the low-frequency humming could be a form of ‘contact call’ between individuals who have been separated from their herd, helping them to find each other in the dark. Some researchers think they sleep talk too.
Acacia trees in Africa communicate with each other. They emit gasses to alert other trees to produce the toxin tannin, which protects them from hungry animals.
South American river turtles talk in their eggs. Turtles don’t have vocal cords, and their ears are internal, so scientists believed that turtles were deaf and didn’t communicate through sounds. However, research has found that turtles communicate at an extremely low frequency that sounds like “clicks, clucks, and hoots” that can only be heard through a hydrophone (a microphone used underwater). These sounds even come from the egg before the turtle hatches. Researchers hypothesize that this helps all the turtle siblings hatch at once.
Kim Kardashian has a ‘glam’ clause in her will. It states that if she’s ever in a position where she can’t get ready herself, can’t communicate, or she’s unconscious, someone has to make sure her hair, nails, and makeup are all perfect.
Herring fish communicate by farting. When herring fish release gas, the bubbles they produce make a high-frequency sound that only herring can hear. The fish use this noise to arrange themselves into “protective shoals” during the night to keep them safe from predators.
