To identify Sicklefin Mullet (Chelon falcipinnis), look at these key features.

Physical Characteristics

Body shape

elongated

Coloration

Dorsal surface typically dark grey to olive-green, fading to silvery-white on the flanks and belly. Fins are generally dusky, with the pectoral fins often having a yellowish tinge at the base.

Scale type

ctenoid

Mouth position

terminal

Distinctive features

Long, falcate (sickle-shaped) pectoral fins, extending beyond the origin of the first dorsal fin., Small, terminal mouth., Adipose eyelid well-developed, covering most of the eye., Two widely separated dorsal fins.

Dorsal fin

Two dorsal fins; the first with 4 spines, the second with 1 spine and 8-9 soft rays.

Tail fin

Moderately forked caudal fin.

Pectoral fin

Long and distinctly falcate, reaching beyond the origin of the first dorsal fin.

Distinctive fins

The elongated, sickle-shaped pectoral fins are the most distinguishing feature.

Identification Tips

1. 1

   Pectoral Fins

   Look for the exceptionally long, curved, and pointed pectoral fins that extend well past the origin of the first dorsal fin. This is the most reliable distinguishing characteristic.

2. 2

   Body Shape and Coloration

   Observe the elongated, somewhat cylindrical body, dark dorsally and silvery ventrally. The overall appearance is typical of mullets, but the fins are key.

3. 3

   Adipose Eyelid

   Note the well-developed adipose eyelid that partially covers the eye, a common feature in many mullet species, but still useful for general identification.
