Benthic fish are species that live on or near the bottom of oceans, rivers, and lakes. They are adapted to their environment, often having flattened bodies that help them stay close to the substrate. Common examples include flounders, catfish, and sculpins. These fish play a crucial role in the ecosystem by feeding on invertebrates and detritus found on the seafloor. These fish can be found in various habitats, from coral reefs to muddy riverbeds. Their behavior and feeding habits are influenced by the availability of food and the type of substrate. Benthic fish are important indicators of environmental health, as changes in their populations can signal shifts in water quality or habitat conditions.
