The sargassum fish, anglerfish, or frog fish, Histrio histrio, is a frogfish of the family Antennariidae, the only species in its genus. It lives among Sargassum seaweed which floats in subtropical oceans These fish usually crawl around on mats of sargassum, or they hang out on rocks
These fish don't hang out on the surface so... it was in the process of going to fish heaven.
With a body of mottled brown and tan, the Sargassum Frogfish projects an ornate rock-like appearance that that of fish. Unlike other frogfish, the skin of this fish is smoother rather than prickly. The Sargassum Frogfish is a master of camouflage in its habitat and can change from light to dark in coloration. It completely mimics the Sagassum algae with folds and tufts of skin. The Sargassum frogfish's skin is covered with dermal flaps, which enable it to blend in even better. Adults are sometimes seen swimming under clumps of floating Sargassum weed. When threatened by a predator the Sargassum Frogfish sometimes jumps out of the water onto the top of an algal mat. It may stay out of water for some time. The Sargassum Frogfish grows up to length of 6 inches.
