What Are Bottom-Dwelling Ocean Fish
Fish at the bottom of the ocean are called benthic species. They live on or near the seafloor, from shallow continental shelves to the deep abyssal plain. Examples include flounder, halibut, cod, and various rattails.
How Fish Survive at Extreme Ocean Depths
Deep-sea fish adapt to high pressure, low light, and cold temperatures. Many have slow metabolisms, flexible bodies, and sensitive organs. Some use bioluminescence to attract prey or communicate in darkness.
Why Bottom-Dwelling Fish Matter
Benthic fish support marine food webs and commercial fisheries. They help recycle nutrients and maintain seafloor ecosystems. Overfishing and habitat damage can disrupt these roles, affecting ocean health and coastal economies.
