The sargassum fish (Histrio histrio) is a member of the frogfish family (Antennariidae) and typically lives in open waters near floating sargassum seaweed, which offers camouflage. Although capable of swimming quite rapidly, this fish often crawls through the sargassum weed, using its pectoral fins like arms.
