In the deep ocean, the majority of vertebrates, or animals with backbones, that we encounter are fish, ranging from important commercial species such as snapper and grouper to sharks and rays, anglerfish, cusk eels, and many others. While these fish are often top predators in the deep and are important components of the deep-sea food web, information about how deep-sea fish live is limited, as it is difficult to make direct observations of these organisms. However, as we learn more about fish and fish communities at different depths, we are building insights into what constitutes a healthy ecosystem, in turn establishing knowledge needed to help managers make the right decisions to conserve resources for future generations. Check out these videos for some of the fishy friends encountered during expeditions.
