It lives among "Sargassum" seaweed which floats in subtropical oceans. The scientific name comes from the Latin "histrio" meaning a stage player or actor, and refers to the fish's feeding behaviour. "Histrio histrio", a strange-looking fish, blends well with its surroundings in its seaweed habitat. It is laterally compressed and its length can reach . The colour of the body and the large oral cavity is very variable, but is usually mottled and spotted yellow, green,
Plant cover Plant cover The abundances of plant species are often measured by plant cover, which is the relative area covered by different plant species in a small plot. Plant cover is not biased by the size and distributions of individuals, and is an important and often measured characteristic of the composition of plant communities. Plant cover data may be used to classify the studied plant community into a vegetation type, to test different ecological hypothesis on plant abundance, and in gradient studies, where the effects of different environmental gradients on the abundance of specific plant species are investigated.
