Rattail fish are very curious and will investigate any disturbance on or around the seafloor. In addition to their large eyes adapted to detect bioluminescent prey, rattails (Macrouridae) can also sense a variety of other food sources using sensory structures on their heads. They communicate with a swim bladder which makes a drumming sound. | MBARI
