How to Identify Reticulated Blenny

To identify Reticulated Blenny (Lipophrys canevae), look at these key features.

Physical Characteristics

Body shape

elongated

Coloration

Variable, typically mottled brown, grey, and reddish hues, forming a reticulated or net-like pattern over the body. This cryptic coloration aids in camouflage. Males often display brighter colors, especially during breeding season, with a dark head and a prominent white spot on the operculum.

Scale type

none

Mouth position

terminal

Distinctive features

Prominent supraorbital tentacles (cirri) above each eye, often branched or fringed., A single, continuous dorsal fin with both spiny and soft rays., Large, blunt head with a relatively large mouth., Absence of scales on the body., Males develop a fleshy crest on the head during breeding season.

Dorsal fin

Single, long dorsal fin with 12-13 spines and 16-18 soft rays. A deep notch often separates the spinous and soft-rayed portions.

Tail fin

Rounded caudal fin.

Pectoral fin

Large, fan-like pectoral fins.

Distinctive fins

Pelvic fins are jugular (located anterior to the pectoral fins) and consist of one spine and two or three soft rays, often appearing filamentous.

Identification Tips

1. 1

   Supraorbital tentacles

   Look for the distinctive branched or fringed tentacles above the eyes, a key characteristic for blennies in general and often specific in form for L. canevae.

2. 2

   Coloration and pattern

   The reticulated (net-like) pattern of browns, greys, and reds on the body is a strong indicator. Males may have a dark head and a white opercular spot.

3. 3

   Absence of scales

   Like many blennies, Lipophrys canevae lacks scales, giving its skin a smooth appearance.

4. 4

   Dorsal fin

   Observe the single, long dorsal fin, noting the number of spines and soft rays if possible, and the presence of a notch.

5. 5

   Habitat

   Its presence in shallow, rocky intertidal and subtidal zones within the Mediterranean and adjacent Atlantic is a strong clue.
