Also known as Underwater Daddy-long-legs. These difficult-to-spot squat lobster feed on zooplankton, and grow to about 7.5cm in length.
Found in deep-water coral and rocky reefs, all over the Western Pacific.
I was at a depth of 30m when I chanced upon this critter. I was trying to see if there was a pygmy seahorse on that sea fan, and I got something else!
