摘要：Seven black brotulas Cherublemma emmelas inhabiting deep-sea soft bottom in the southeastern Gulf of California were collected using a benthic sledge during 2 oceanographic cruises (TALUD project) at a depth range of 905 to 1 010 m, a temperature range of 4.6 to 5.2°C, and hypoxic (0.13 to 0.20 ml/l) conditions. Until now, the presence of C. emmelas below 750 m had not been reported in the literature. This new record extends the known depth range of occurrence approximately 260 m deeper than the previously reported limit.
