| Many families of fish include both sea fish and fresh water fish, as for instance, the thornback. |
| It's an unusual find on this coast, with thornback being the most copmmon rays, and they turn up only occasionally. |
| The thornback is another ugly fellow of this family, having spines on his back and a double row of them down his tail. |
| The boy gave a curious half-sad smile, without turning his eyes from the thornback, and said nothing. |
| The most common are dragonets, topknots, dabs, plaice and, if you're lucky, the occasional anglerfish and thornback ray. |
| Thornback and blond rays are most often seen, with brill, plaice, sole, flounder and even turbot on occasion. |
