Patchy throughout northern GOM from 370 to 1048 m depth. First Record in GOM . This species was described by Bigelow and Schroeder (1958) based on three specimens ( holotype USNM 156712 , Figure 2 , and paratypes MCZ 39618) collected from the northern GOM off of Florida aboard the RV Oregon in 1955 ( Springer and Bullis 1956 ) . Remarks. This species is rare and little is known about its biology. However, recent observations made during deepwater habitat surveys conducted by the National Oceanic and Atmospheric Administration (NOAA) Office of Ocean Exploration and Research (OOER) in the northern GOM utilizing a remotely operated vehicle (ROV) have yielded additional insights into the morphology and habitat preferences of this species, including a new maximum depth record ( 1048m , C. Jones unpublished data). Conservation Status. Data Deficient
