How to Identify Southern Klipfish

To identify Southern Klipfish (Clinus superciliosus), look at these key features.

Physical Characteristics

Body shape

elongated

Coloration

Extremely variable, ranging from mottled browns, greens, reds, and greys, often mimicking the surrounding algae, rocks, or invertebrates. Can change color rapidly to match its environment. Often exhibits bands, spots, or blotches. Males may display brighter breeding colors.

Scale type

none

Mouth position

terminal

Distinctive features

Prominent, branched cirri (fleshy appendages) above each eye, which are often fringed or leaf-like., Large head with a relatively large mouth., Continuous dorsal fin with numerous strong spines., Absence of scales (body is naked or covered in minute, embedded scales)., Pelvic fins are jugular (located in front of the pectoral fins) and modified into two rays, one of which is often thickened.

Dorsal fin

Long and continuous, originating above the operculum, with 30-37 spines and 5-9 soft rays. The spiny portion is significantly longer than the soft-rayed portion.

Tail fin

Rounded or truncate caudal fin.

Pectoral fin

Well-developed and rounded, typically with 11-13 rays.

Distinctive fins

Pelvic fins are reduced to two rays, one of which is often stout and unbranched, located anterior to the pectoral fins.

Identification Tips

1. 1

   Supraorbital Cirri

   Look for the distinctive, often branched or fringed, fleshy appendages (cirri) located directly above each eye. The shape and complexity of these cirri can vary but are a key identifying feature for Clinus superciliosus.

2. 2

   Coloration and Pattern

   Observe the highly variable coloration and patterning. While it can be challenging due to camouflage, look for mottled patterns of browns, greens, reds, or greys that help it blend with its surroundings. The ability to rapidly change color is also indicative.

3. 3

   Dorsal Fin

   Note the long, continuous dorsal fin with a prominent spiny anterior portion (30-37 spines) followed by a shorter soft-rayed portion (5-9 rays). This fin structure is characteristic of clinids.

4. 4

   Pelvic Fins

   Examine the pelvic fins, which are located anterior to the pectoral fins (jugular) and are reduced to two rays, one of which is often noticeably thicker and unbranched.

5. 5

   Body Shape and Size

   Identify its elongated, somewhat compressed body, typically reaching a maximum length of about 30 cm, though most individuals are smaller (15-20 cm).
