Little is known about the biology and ecology of mesopelagic medusae. In part, this is because midwater trawls are used to collect fragile medusae and other gelatinous macroplankton. Additionally, nets cannot provide data on behavior and on biotic associations. Herein, in situ observations on northwestern Atlantic midwater medusae made using the Johnson-Sea-Link submersibles are reported. Included are depth and temperature ranges; notes on pigments; locomotory behavior; and notes on prey and predators.
