Four different kinds of hydrozoan medusae, two of scyphozoans, and four of siphonophores are recorded from three basins of southern California, largely in depths greater than 4000 feet. The records are based on photographs made with a special underwater camera which is described. These coelenterates show specific distributional patterns which appear to reflect not only limited tolerances to temperatures, but also preferences for certain foods either near the sea floor or in the sound‐scattering layers.
