Apri l'appDescrizione
Salaria pavo, commonly known as the Peacock Blenny, is a small, benthic marine fish belonging to the family Blenniidae. It is characterized by its vibrant coloration, particularly in males during breeding season, and its distinctive supraorbital tentacles. This species is well-adapted to life in shallow, rocky coastal areas, often found in tide pools and intertidal zones. It exhibits fascinating territorial and reproductive behaviors, including male parental care.
Caratteristiche fisiche
- Forma del corpo
- elongated
- Colorazione
- Highly variable. Males are typically more brightly colored, especially during breeding, displaying iridescent blue, green, and orange spots and stripes on a brownish or greenish-grey background. Females are generally duller, with mottled brown and grey patterns. A prominent dark spot, often ocellated with a lighter ring, is usually present on the anterior dorsal fin.
- Tipo di squame
- none
- Posizione della bocca
- inferior
- Caratteristiche distintive
- A pair of branched supraorbital tentacles above each eye, more prominent in males., A nuchal crest (fleshy ridge) on the head, particularly developed in breeding males., A prominent dark ocellated spot on the anterior part of the dorsal fin.
- Pinna dorsale
- Single, long dorsal fin with 12-13 spines and 17-19 soft rays. A deep notch separates the spinous and soft-rayed portions.
- Pinna caudale
- Rounded caudal fin.
- Pinna pettorale
- Large, fan-like pectoral fins.
- Pinne distintive
- Pelvic fins are jugular (located anterior to the pectoral fins) and consist of 1 spine and 2-3 soft rays.
Consigli per l'identificazione
Supraorbital Tentacles
Look for the branched, fleshy appendages above each eye. These are a key distinguishing feature from many other blenny species.
Dorsal Fin Spot
Observe the prominent dark, often ocellated (eye-like) spot on the anterior part of the dorsal fin. This is a consistent marker.
Coloration (Males)
During breeding season, males display striking iridescent blue, green, and orange markings, making them easily identifiable.
Nuchal Crest
In breeding males, a noticeable fleshy crest on the head becomes more pronounced.
Habitat
- Tipo di acqua
- saltwater
- Profondità
- Intertidal zone down to approximately 5 meters (16 feet), occasionally deeper.
- Ambiente
- Rocky shores, tide pools, shallow coastal waters with algal growth, seagrass beds, and areas with abundant crevices for shelter. Often found in brackish water environments near river mouths.
- Areale geografico
- Eastern Atlantic Ocean (from Portugal to Morocco, including Madeira and the Canary Islands) and the Mediterranean Sea, extending into the Black Sea.

Fatti chiave
Sex Changebehavior
Salaria pavo is a protogynous hermaphrodite, meaning individuals are born female and can later change sex to male. This is often observed in larger, older individuals.
Territorial Malesbehavior
Males are highly territorial, especially during the breeding season, aggressively defending their nesting sites (often crevices or empty shells) from rivals.
Parental Carebehavior
After spawning, the male Peacock Blenny guards the eggs, fanning them to ensure oxygenation and protecting them from predators until they hatch.
Air Breathingbehavior
Like some other blennies, Salaria pavo can survive out of water for short periods by breathing atmospheric air, a useful adaptation for life in tide pools.
Algal Grazersbehavior
Their diet primarily consists of benthic algae, which they scrape from rocks using their comb-like teeth, playing an important role in controlling algal growth in their habitat.
Informazioni di sicurezza
Sicuro- Livello di sicurezza: safe
- Velenoso: No
- Commestibilità: not recommended
- Note sul maneggio: Generally harmless. Can deliver a small, harmless bite if handled carelessly, but poses no significant threat. Observe from a distance in their natural habitat.
Specie simili
Tompot Blenny
Parablennius gattorugine
The Tompot Blenny has much longer, unbranched supraorbital tentacles and lacks the prominent ocellated spot on the dorsal fin. It also typically inhabits slightly deeper waters.
Sphinx Blenny
Aidablennius sphynx
The Sphinx Blenny has simple, unbranched supraorbital tentacles and a different pattern of spots and stripes on its body. Its dorsal fin spot, if present, is less prominent and not ocellated.
Ringneck Blenny
Parablennius pilicornis
The Ringneck Blenny has branched supraorbital tentacles, but they are generally shorter and less elaborate than those of Salaria pavo. Its coloration and body markings also differ, often featuring vertical bands.
