Parablennius incognitus, commonly known as the Incognito Blenny or Babica kamenjarka, is a small, benthic marine fish belonging to the family Blenniidae. It is characterized by its elongated body, prominent eyes, and a distinctive supraorbital cirrus. This species is often found in shallow, rocky coastal areas, where it inhabits crevices and empty mollusc shells. It is known for its cryptic coloration, which allows it to blend seamlessly with its surroundings, making it challenging to spot. Males exhibit vibrant breeding coloration during the reproductive season.
Fizične značilnosti
- Oblika telesa
- elongated
- Obarvanost
- Highly variable, typically mottled brown, grey, or greenish with darker spots and bands, providing excellent camouflage. Males in breeding season develop a darker head, often blackish, with bright yellow or orange spots on the operculum and fins. Females and non-breeding males are generally duller.

- Pelvic fins are jugular, located anterior to the pectoral fins, with one spine and two soft rays.
Nasveti za prepoznavanje
Supraorbital Cirri
The most reliable distinguishing feature is the single, branched cirrus above each eye. Count the branches (typically 3-7). Other similar blennies may have unbranched cirri or multiple cirri.
Nuchal Cirri
Absence or very small, unbranched nuchal cirri (on the nape) helps differentiate it from species like Parablennius tentacularis which has prominent nuchal cirri.
Coloration and Pattern
While variable, the mottled pattern and the specific breeding coloration of males (dark head, yellow/orange spots) can be indicative. Observe the overall body shape and fin structure.
Habitat Preference
Its preference for shallow, rocky areas with abundant hiding spots is a good indicator. Look for it peeking out of holes or resting on rocks.
Habitat
- Vrsta vode
- saltwater
- Globina
- From the intertidal zone down to approximately 20 meters, most commonly found in shallower waters (0-5 meters).
- Okolje
- Rocky shores, tide pools, shallow reefs, seagrass beds, and areas with abundant algal growth. Prefers habitats with numerous crevices, holes, and empty mollusc shells (e.g., barnacle shells, gastropod shells) for shelter and spawning.
- Geografska razširjenost
- Eastern Atlantic Ocean (from Portugal to Morocco, including Madeira and the Canary Islands) and the Mediterranean Sea, including the Black Sea. It is particularly common in the Adriatic Sea.

Ključna dejstva
Cryptic Masterinteresting
The species name 'incognitus' (Latin for 'unknown' or 'hidden') refers to its excellent camouflage and the fact that it was often overlooked or misidentified as other blenny species before its formal description.
Homebodybehavior
Babica kamenjarka is highly territorial, especially males during breeding season. They will fiercely defend their chosen crevice or shell, which serves as both shelter and a nesting site.
Parental Carebehavior
Males of Parablennius incognitus exhibit parental care, guarding the eggs laid by females within their chosen shelter until they hatch. This behavior is common among blennies.
Dietary Flexibilitybehavior
While primarily herbivorous, feeding on benthic algae, P. incognitus is an opportunistic omnivore and will also consume small invertebrates, detritus, and zooplankton.
Sexual Dimorphisminteresting
During the breeding season, males undergo a dramatic color change, developing a dark head and vibrant yellow or orange spots, making them much more conspicuous than females or non-breeding males.
