Thank you to Dr Joseph Nelson for identifying the fish.
The species was described by Dr Ron Fricke in 1990. When asked for comments about this page, Ron replied: " Interesting photograph. This represents a new depth record (the species was originally described from 350-740 m depth). But I agree with the identification as Psychrolutes occidentalis Fricke, 1990. Very nice photographic quality for an ROV picture, but the Psychrolutes wouldn't move much anyway; they are supposed to be sluggish and slow moving, as they have soft, mostly catilaginous, decalcified bones."
The fish looks similar to the Smooth-head Blobfish, Psycholutes marcidus, which occurs off eastern Australia. The famous Mr Blobby, Psychrolutes sp., may in fact be a Smooth-head Blobfish.
