The reef is full of dangers 🌊 The Orange-spotted Filefish has a wild trick—it smells like the coral it eats, fooling predators! Often seen in pairs, it’s double trouble. 🧡🐟 #CoralConnections #ReefMagic #OceanAdaptations https://t.co/Fuhx6z79SI

This Candy Basslet (Liopropoma carmabi)—which I photographed her in the Steinhart Aquarium’s Twilight Zone exhibit—is a vivid reminder of the hidden beauty thriving in mesophotic reefs. Rarely seen, but impossible to forget. 🌊🔦 #TwilightZoneExhibit #HiddenDepths https://t.co/4EVz

The Black-lined Sleeper Goby (Valenciennea helsdingenii) is common on sheltered reefs and estuaries throughout the Indo-Pacific. They are usually seen in pairs of small groups, and I was lucky to photographed these two here perfectly lined up! #ichthyology #NastyGoby #Indonesia h

For a long time people assumed that #mesophotic ecosystems were untouched refuges for shallow coral reef fauna. Our new paper in @sciencemagazine today shows that this is not the case! Deep reefs are unique and threatened! https://t.co/z99IpIvSpa https://t.co/lxuPFAEoMh
