Gilthead bream vs Common dentex
How to tell them apart, and what follows from getting it right.
Why they get confused
Two large Sparidae of the same Mediterranean and eastern Atlantic ground, both deep-bodied, both silver-grey, and both taken on the same baits over the same rough bottom.

Sparus aurata — Sparidae
Common dentex
Dentex dentex — Sparidae

The differences
Each difference is marked with how far it can be trusted on its own. A single diagnostic character settles the identification; suggestive ones only narrow it.
| Character | Gilthead bream | Common dentex | Reliability |
|---|---|---|---|
| Mark between the eyesIdentification | A golden band between the eyes — the mark the common name refers to. | No golden band; the forehead is plain, steeper and heavier in old fish. | Diagnostic on its own |
| TeethIdentification | Rounded crushing molars at the back of the jaw, suited to shellfish. | Prominent canine teeth at the front of the jaw, suited to fish prey. | Diagnostic on its own |
| FeedingFeeding | A hard-shelled-prey specialist whose whole jaw is built for crushing. | An active predator of fish and cephalopods, hunting in mid-water as well as on the bottom. | Supporting — use with others |
| Dark shoulder markIdentification | A dark blotch at the origin of the lateral line, above the gill cover. | No comparable shoulder blotch; older fish are speckled over the whole upper flank. | Supporting — use with others |
Why it matters
The two feed completely differently, so the identification is also the explanation of why one took a shellfish bait and the other took a fish bait. Minimum sizes also differ in most Mediterranean jurisdictions.
