Bellottia robusta

Common Name

Robust Brotula

Year Described

Nielsen, Ross & Cohen, 2009


Dorsal Fin: 85-93
Anal Fin: 75-88
Pectoral Fin: 23-25
Caudal Fin: 7
Vertebrae: 12 precaudal, 48-51 total
Gill Rakers: 5-6 (long rakers)

Body short and robust (depth at anal fin origin 17.5-23% SL). Tail tapering. Head very large (>30% SL). Head pores well developed. Mouth large. Fangs poorly developed. Preopercle with four obvious spines on margin and one at top. Opercular spine covered in skin. Spine present on cleithrum above pectoral base. Dorsal fin near mid-body. Anal fin far back (below dorsal ray 10-18). Dorsal and anal fins continuous with tail. Pelvic fins absent. Pectoral fin fanlike with a short peduncle. Body fully scaled. Head only partly scaled.


Body uniformly dark to medium brown. Fins lighter in color.


Specimens range from 34-82mm SL.


Seems to be associated with hard bottom habitats on deep Lophelia reefs or on rocky substrate (506-580m).


Gulf of Mexico: known from a handful of specimens off the Mississippi Delta.

Other Notes

This genus is known from very few specimens but the two Atlantic species seem to be distinguished by the number of precaudal vertebrae, the presence of a spine on the preopercular crest, origin of anal fin, and body depth (Nielsen et al., 2009).
