How to Identify Florida Gar

To identify Florida Gar (Lepisosteus platyrhincus), look at these key features.

Physical Characteristics

Body shape

elongated

Coloration

Olive to brownish-green dorsally, fading to a lighter, often whitish, ventral surface. Distinctive dark brown to black spots are present on the body, fins, and notably on the top of the head and snout. The intensity and distribution of spots can vary.

Scale type

ganoid

Mouth position

superior

Distinctive features

Elongated, cylindrical body, Long, relatively broad snout, Ganoid scales (diamond-shaped, interlocking, bony scales), Dorsal and anal fins positioned far back on the body, near the caudal fin, Numerous sharp, conical teeth in both jaws, Spots on the top of the head and snout

Dorsal fin

Single dorsal fin, located far posterior on the body, typically with 6-9 rays.

Tail fin

Abbreviated heterocercal caudal fin (appears somewhat rounded or truncate, but the vertebral column extends into the upper lobe).

Pectoral fin

Paired pectoral fins, relatively small.

Distinctive fins

Pelvic fins are abdominal, located far back on the belly. All fins are typically spotted.

Identification Tips

1. 1

   Snout Length and Width

   The Florida Gar has a relatively short and broad snout compared to the Longnose Gar. The snout length is typically less than 50% of the head length, and its width at the nostrils is usually greater than the eye diameter.

2. 2

   Spots on Head

   Presence of distinct dark spots on the top of the head and snout is a key diagnostic feature for the Florida Gar, differentiating it from the Spotted Gar (L. oculatus) which typically lacks these spots on the head itself, though it has spots on the body and fins.

3. 3

   Lateral Line Scales

   Count the number of scales along the lateral line. Florida Gars typically have 54-62 lateral line scales.

4. 4

   Body Spotting

   While all gars can have some spotting, the Florida Gar's spots are generally well-defined and cover the body, fins, and head.
