Sargassum frogfish

The Sargassum frogfish, Histrio histrio, is a marine fish notable for its mottled brown and greenish coloration, designed to blend seamlessly with its primary habitat amidst floating sargassum seaweed. Originating from tropical and subtropical waters around the globe, this species exhibits a distinctive appearance with a stocky, somewhat flattened body and appendages that resemble seaweed, aiding in its camouflage. It is not commonly known in the aquarium hobby, primarily due to its specialized habitat and lifestyle needs that are difficult to replicate in captivity.
