Identification Tips

1. 1

   Size

   Cubera Snappers are the largest snapper species in the Atlantic, commonly reaching over 1 meter (3.3 feet) and exceeding 50 kg (110 lbs). Record individuals can approach 1.6 meters (5.2 feet) and over 70 kg (150 lbs).

2. 2

   Canine Teeth

   Look for two very prominent, large canine teeth in the upper jaw that are often visible even when the mouth is closed. These are significantly larger than those of other snapper species.

3. 3

   Coloration

   Adults are generally uniform grey to dark brown/reddish-brown, lacking the distinct spots, lines, or bars seen on many other snappers. Juveniles may have faint bars.

4. 4

   Vomerine Tooth Patch

   The vomerine tooth patch (on the roof of the mouth) is anchor-shaped with a distinct posterior extension, a key diagnostic feature for ichthyologists.

5. 5

   Absence of Dark Spot

   Unlike many other snapper species (e.g., Gray Snapper, Mutton Snapper), the Cubera Snapper lacks a prominent dark spot below the anterior soft dorsal fin rays.
