Lipophrys pholis, commonly known as the Shanny or Babica balavica in some regions, is a small, benthic marine fish belonging to the family Blenniidae. It is characterized by its elongated body, large head, and prominent eyes. This species is well-adapted to intertidal and shallow subtidal rocky environments, where it uses its robust pectoral fins to navigate crevices and hide from predators. Its coloration is highly variable, allowing it to camouflage effectively with its surroundings. The Shanny is a territorial and opportunistic feeder, playing an important ecological role in its habitat.

Nasveti za prepoznavanje
Body Shape and Head
Look for an elongated, somewhat compressed body with a large, blunt head and prominent, high-set eyes. The overall appearance is robust.
Coloration
Observe the highly variable, mottled camouflage patterns of browns, greens, and greys. Males may show brighter colors during breeding. The absence of scales is a key feature.
Dorsal Fin
Note the single, long dorsal fin that runs almost the entire length of the back, with a distinct spiny and soft-rayed section, sometimes with a slight notch.
Pectoral and Pelvic Fins
Identify the large, fan-like pectoral fins and the small, jugular pelvic fins located under the throat.
Absence of Tentacles
Unlike many other blenny species, Lipophrys pholis typically lacks prominent supraorbital or nasal tentacles, which helps in differentiation.
Habitat
- Vrsta vode
- saltwater
- Globina
- Intertidal zone down to approximately 30 meters, most commonly found in shallow waters.
- Okolje
- Rocky shores, tide pools, crevices, under stones, and among seaweed. Prefers areas with good cover and shelter from strong currents and wave action.
- Geografska razširjenost
- Northeastern Atlantic Ocean, from Norway south to Morocco, including the Mediterranean Sea (especially the western basin) and the Black Sea. Common around the British Isles and along the European Atlantic coast.

Ključna dejstva
Terrestrial Adaptationsamazing
Shannies are remarkably tolerant of being out of water for extended periods, especially during low tide. They can breathe air through their skin and gills, allowing them to survive in tide pools that may become isolated or even completely dry out for a short time.
Parental Carebehavior
Male Shannies exhibit strong parental care. After the female lays her eggs in a crevice or under a rock, the male guards and aerates the eggs until they hatch, often for several weeks.
Dietary Flexibilitybehavior
While primarily carnivorous, feeding on small crustaceans, mollusks, and worms, Shannies are also known to consume algae and detritus, demonstrating a degree of dietary flexibility.
Color Changeinteresting
Their ability to rapidly change color allows them to blend seamlessly with their surroundings, providing excellent camouflage against predators and aiding in ambush hunting.
Varnostne informacije
Varna- Stopnja varnosti: safe
- Strupena: Ne
- Užitnost: not recommended
- Opombe o ravnanju: Generally safe to handle, but like all fish, they can bite if provoked or handled carelessly. Their small teeth are not dangerous but can cause minor nicks. Always handle with wet hands to protect their skin and mucus layer.

Tompot Blenny
Parablennius gattorugine
The Tompot Blenny has prominent branched tentacles above each eye and often has distinct dark vertical bands on its body. It also tends to be larger and has a more pointed snout than the Shanny.
Montagu's Blenny
Coryphoblennius galerita
Montagu's Blenny is smaller and possesses a distinctive fleshy crest or comb on its head, which the Shanny lacks. Its coloration is also typically more uniform.
Butterfly Blenny
Blennius ocellaris
The Butterfly Blenny is easily distinguished by the large, ocellated (eye-spot) spot on its dorsal fin, which is absent in the Shanny. It also has prominent supraorbital tentacles.
