Skull structure looks very similar to Aussie lungfish in a way. Plenty of muscle built in with larger lower jaw. However the teeth is doesn't look like of a predatory fish but more look like a teeth of a herbivore as it look like a horse teeth. Again no gular plate just like the aussie lungfish. Used pure muscle power for bite force. You can see the hallow space on the upper side of the skull. Its where are the muscle are mostly present.
Don't worry this is not my aba aba. I got this from a friend of mine when his aba aba died at 21".
