How to Identify Coney

To identify Coney (Cephalopholis fulva), look at these key features.

Physical Characteristics

Body shape

torpedo

Coloration

Highly variable, exhibiting several distinct color phases: 1. Red/Orange Phase: Body is typically reddish-orange to reddish-brown, often with small, scattered blue spots. 2. Bicolor Phase: Anterior half of the body is dark brown or black, sharply demarcated from a white or pale posterior half. 3. Brown Phase: Uniformly brown or grayish-brown, sometimes with faint banding. All phases typically have two small, dark spots (ocelli) on top of the caudal peduncle, which can be prominent or faint depending on the individual and its mood. The fins usually match the body color, often with blue margins or spots.

Scale type

ctenoid

Mouth position

terminal

Distinctive features

Two prominent dark spots (ocelli) on the dorsal surface of the caudal peduncle, near the base of the caudal fin. These spots are a key diagnostic feature, though their intensity can vary., Highly variable coloration (polymorphism) with red, bicolor, and brown phases., Relatively large mouth with small, sharp teeth., Slightly convex interorbital space., Rounded caudal fin.

Dorsal fin

Single dorsal fin with IX spines and 17-19 soft rays. The spinous and soft-rayed portions are continuous.

Tail fin

Caudal fin is rounded.

Pectoral fin

Pectoral fins are relatively large and rounded, with 16-18 rays.

Distinctive fins

Pelvic fins are thoracic, originating below or slightly anterior to the pectoral fin base. Anal fin has III spines and 8-10 soft rays.

Identification Tips

1. 1

   Caudal Peduncle Spots

   Look for the two small, dark ocelli on the upper part of the caudal peduncle, just before the tail fin. These are almost always present, though their visibility can vary.

2. 2

   Color Polymorphism

   Be aware of the three main color phases: red/orange with blue spots, bicolor (dark front, pale rear), and uniform brown. All are the same species.

3. 3

   Fin Shape

   The rounded caudal fin is a good distinguishing feature among some groupers.

4. 4

   Size

   Adults typically reach a maximum length of about 41 cm (16 inches), but are more commonly observed around 20-30 cm (8-12 inches).
