How to Identify Yellowstripe Goatfish

To identify Yellowstripe Goatfish (Parupeneus chrysopleuron), look at these key features.

Physical Characteristics

Body shape

elongated

Coloration

The body is typically silvery-white to pale pinkish-white dorsally, fading to white ventrally. A prominent, bright yellow to golden-orange stripe extends from the snout, through the eye, and along the lateral line to the caudal peduncle. The fins are generally translucent to yellowish. Some individuals may display faint reddish blotches or bars on the upper body, particularly when stressed or at night. The barbels are white or pale yellow.

Scale type

ctenoid

Mouth position

terminal

Distinctive features

A single, prominent yellow to golden-orange stripe along the lateral line., Two long, prominent chin barbels used for foraging., Two widely separated dorsal fins.

Dorsal fin

Dorsal fin I: VIII spines; Dorsal fin II: 1 spine, 8 soft rays. The first dorsal fin is typically higher than the second.

Tail fin

Forked caudal fin.

Pectoral fin

Pectoral fins are relatively short, with 16-17 rays.

Distinctive fins

Pelvic fins are thoracic, located directly below the pectoral fins, with 1 spine and 5 soft rays. Anal fin has 1 spine and 6 soft rays.

Identification Tips

1. 1

   Lateral Stripe

   Look for the distinct, bright yellow to golden-orange stripe running horizontally from the snout to the tail. This is the most reliable identifying feature.

2. 2

   Chin Barbels

   Observe the two prominent, white or pale yellow barbels extending from the chin, characteristic of all goatfish species, used for sensing prey.

3. 3

   Dorsal Fins

   Note the two separate dorsal fins, with the first dorsal fin typically taller than the second.

4. 4

   Body Shape and Color

   The elongated, somewhat compressed body, silvery-white to pale pinkish coloration, and the presence of the yellow stripe distinguish it from many other reef fish.
