👉 Sargassumfishes are a group of fish that inhabit the water column in the Southern Ocean and other areas where warm water is available. They are also known as "sargasso fishes" due to their presence in the Northern Hemisphere's Atlantic Ocean, which is often referred to as the "sargasso sea". These fish have adapted to living in marine environments with a high salinity level, allowing them to thrive in conditions that would be inhospitable for other fish species.
