Abstract

This paper describes direct video observations of two manefishes, likely Paracaristius sp., from the mesopelagic waters of the north-central Gulf of Mexico. One fish was observed with a remotely operated vehicle at a depth of 829 m by an industrial ROV as part of the SERPENT Project. The second was observed at 496 m from a manned submersible. Little is known about the behavior of manefishes because most records result from net-collected material. Our observation demonstrates that manefishes are capable of precise locomotory and posture control using extended, erect fins and that the pelvic fins of these fishes are extended in a parachute-like manner. Moreover, one of the specimens exhibited an unusual vertical, sinusoidal oscillation of its caudal fin. One of the observations took place in association with a physonect siphonophore. These observations may include the deepest published record for a manefish in the Gulf of Mexico.
