Question: What's the most common fish in the ocean?
Answer: The most common fish is any of the species of a deepwater fish sometimes called a "bristle mouth." The fish is about the size of a small minnow. It is caught at 500 meters or deeper all over the world.
The tan bristlemouth is a small deep-sea fish that lives in the mesopelagic zone of the open ocean. Together, the bristlemouth fishes in the genus Cyclothone are considered by scientists to be the most abundant vertebrates on Earth. Though they are extremely abundant, they live in a difficult environment to study and are particularly fragile when captured in deep-sea nets, so there is relatively little information known about their biology and ecology.
