Turn off the lights, and we'll glow. ⚡️🌊✨ Fluorescence is a process where high-energy light temporarily excites electrons in a molecule. When the molecule relaxes, the energy is re-emitted as a lower-energy photon with a longer wavelength. Unlike bioluminescence, it is not something that animals can actively turn on and off. For this video, MBARI scientist Steve Haddock filmed the fluorescence of strawberry anemones at the @montereybayaquarium by shining a blue light on them and putting a yellow filter in front of the lens. The filter blocks out the excitation light but lets the fluorescent light be recorded. You can try it at home with a piece of yellow plastic and a blue LED flashlight. You might be surprised by what you find!

We're looking at you, weekend... Many deep-sea animals have specialized eyes for seeing in the dim light of the deep. This juvenile squid in the genus Galiteuthis has photophores (light organs) around its eyes. It was spotted by our scientists this week during the Bioinspiration Lab's research expedition at sea. This species lives in the North Pacific from 200 to over 1,000 meters (656 to 3,280 feet) deep. We often encounter them hanging horizontally in the water column with their arms above their head, as we did here with ROV Doc Ricketts. #MBARI #cephalomania #cephalopods #deepsea #ocean #nature #explore #science #exploremore #wildlife #underwaterphotography #nofilter
