Other bottom feeders occur in less numbers, the pollock and the cusk perhaps being next in order of importance, with hake and a considerable amount of the various Flatfishes in the otter trawls.

You see how truly your prediction regarding the flatness of the creature's head is substantiated by these casts; it is really not easy to know how, placed on so flat a surface, the eyes could have been very available save for star-gazing; but as nature makes no mistakes in such matters, it is possible that the creature, like the Flatfishes, may have lived much at the bottom, and that most of the seeing it had use for may have been seeing in an upward direction.
