WATCH: Wild Corals Caught 'Kissing' on Camera

(Credit: Jan Mallander/Pixabay) A first-of-its-kind underwater microscopic imaging system is giving scientists an up-close perspective on the frenzied daily lives of corals. Corals appear fairly sedate when viewed from on high, but they're abuzz with activity that occurs on scales too small for us to see with the naked eye. Fully zoomed in, scientists observed coral polyps engaging in the "three Fs" of existence: fighting, feasting and...making love within their vast colonies. Spying on the way coral engage in these essential behaviors will give researchers new insights into how the coral communities live and how they die — important work during a period of unprecedented bleaching events.
