If evidence from fossil and living forms is combined, the Agnatha are distinguishable from the other craniates (Gnathostomata) by what they lack: jaws, lateral fins supported by fin rays, vertebrae, a horizontal semicircular canal in the ear, and genital ducts.

The wave at Belharra, which breaks in deeper water, is easily as tall as Jaws, but it lacks the pronounced trough, vertical wall and gaping barrel that make Jaws so dangerous -- and easy to measure.
The skull also had strange cranial crests, and the jaws lacked teeth but were probably sheathed with a horny, beaklike covering.
