Has anyone ever seen a fish like this? It seemed to be missing it top jaw.

Interesting deformation! Actually - as far as I know - things like this are
not really uncommon and are mainly caused during the embryo or fry stage.
The reason can be either genetic, chemically or mechanically induced.

Uncommon is the fact the fish grew this big - most don't cope well with the
deformation and are predated on fairly early in their lives.

Minor deformations of the spine seem to be more commonly observed - probably
due to having a less violent impact on the fish.
