How to identify common dentex
Dentex dentex · Sparidae
The characters that identify common dentex, ranked by how far each one can be trusted on its own.
Safety
Injury while handling fish — Can cause injury needing treatment
Prominent canine teeth and firm gill covers on a strong fish handled at close quarters.
What reduces it: Keep fingers clear of the mouth and gill plates, wet hands, and use a tool rather than fingers for unhooking or for removing a shaft.
Look at this first
Open the mouth. Four large widely spaced canines at the front of each jaw, unlike anything else in the Mediterranean sea breams, and the origin of both the common and the scientific name. On a big fish the domed forehead confirms it before you get that far.
Diagnostic — settles it on its own
Each of these settles the identification on its own. If one is clear, you have your answer.
Large widely spaced canines in both jaws
Prominent conical teeth at the front of the upper and lower jaws, well separated from one another. The other large sparids in the same water have crushing molars or fine incisors instead, so this settles the genus immediately.
Supporting — use with other characters
Real characters that are not conclusive by themselves. Use two or three together.
A steep forehead that becomes a hump
The profile rises sharply from the snout, and in large males the forehead builds into a pronounced bulge that makes the fish unmistakable in silhouette. Age and sex dependent, which is why it sits below the teeth.
A single unbroken dorsal fin on a powerful body
The dorsal runs the length of the back without a notch, over a body that is deep but built like a predator rather than a disc. It separates dentex from the deeper, rounder breams at a glance underwater.
Suggestive only — varies with condition
Hints only. These vary with condition, season, water and how long the fish has been out of it, and a fish that contradicts them is still the same species.
Fine dark speckling on the upper flank
Small dark spots scattered above the lateral line on younger fish, fading with age until a large adult has none. Useful on a small fish and misleading on a big one.
What it gets confused with
- Other Dentex species in the eastern Atlantic and around the Canaries, which share the dentition.
- Large gilthead bream and other big sparids at a distance, until the head profile or the teeth are visible.
- Meagre in Mediterranean water, separated by body depth and the entirely different mouth.

Where this stops working
Colour is unusable: dentex photographed at twenty metres are blue-grey because the water has removed the warmer wavelengths, and the same fish on a boat is a different animal to look at. Several congeners overlap at the southern end of the range. Where the fish is taken by spearfishing the identification and the size judgement both have to be made before the shot, which is a stronger requirement than any rod fishery imposes.

Telling it apart is one question. Here are the others.
Similar and related fish
Common pandoraSparids of the same waters separated by dentition, body depth and colour.- European anchovySmall shoaling clupeids and anchovies are taken in open water, which is when dentex move off the structure they otherwise hold to.
Gilthead breamBoth are Sparidae and neither is what its market name suggests. The dentex hunts fish with canines; the gilthead crushes shellfish with molars. Same family, opposite equipment.

Where you will find it
- Balearic IslandsPresent over rocky ground and drop-offs, and one of the large predators the Mediterranean spearfishing tradition here is built around.
- ItalyA fast, wary open-water sparid of Italian rock and reef ground, and one of the fish the country's ambush breath-hold technique was developed to approach.
- MediterraneanThe most prized spearfishing target across much of the sea, and the benchmark by which divers there judge a session — mobile, extremely wary, and seen for a few seconds at the edge of visibility.
- The Croatian AdriaticOver the karst walls, drop-offs and rubble where it hunts actively rather than holding a spot. It is the species Adriatic spearfishers rate above all others, and its vulnerable assessment is exactly why the local conversation about restraint is more advanced than the regulation.
- The Strait of GibraltarOccupies the rocky margins on both sides, hunting in clear water over current-swept hard ground.
