Abrir o appDescrição
Labrus bergylta, commonly known as the Ballan Wrasse or Maragota, is a robust and colorful marine fish belonging to the family Labridae. It is characterized by its thick lips, strong teeth, and variable coloration, which allows it to blend effectively with its rocky reef habitats. This species is a protogynous hermaphrodite, meaning individuals mature as females and can later change sex to male. It plays an important ecological role as a predator of benthic invertebrates.

- Coloração
- Highly variable, ranging from green, brown, reddish-brown, to orange, often mottled or spotted with lighter or darker patches. Juveniles tend to be greener. Coloration can change rapidly depending on mood, habitat, and reproductive state. Males often develop more intense coloration during breeding.

Dicas de identificação
Coloration
Observe the highly variable mottled pattern of greens, browns, reds, and oranges. This is a key identifier, though it can be confusing due to its variability.
Lips and Teeth
Note the thick, fleshy lips and the prominent, conical teeth. These are characteristic of wrasses and particularly pronounced in the Ballan Wrasse.
Dorsal Fin
Count the spines and soft rays in the single, long dorsal fin (18-21 spines, 9-13 soft rays). The spiny part is noticeably longer.
Body Shape
Its robust, compressed body and relatively large size (up to 60 cm) distinguish it from many other wrasse species in its range.
Habitat
- Tipo de água
- saltwater
- Profundidade
- Typically found from the intertidal zone down to about 50 meters (164 feet), occasionally deeper to 100 meters (328 feet).
- Ambiente
- Prefers rocky reefs, kelp beds, seagrass meadows, and areas with abundant algal growth, providing shelter and foraging opportunities. Juveniles often inhabit shallower, more sheltered areas.
- Distribuição geográfica
- Eastern Atlantic Ocean, from Norway and the British Isles south to Morocco, including the Azores, Madeira, and the Canary Islands. Also found in the western Mediterranean Sea.

- Compatibilidade: Best kept in a species-specific tank or with other large, robust, and non-aggressive temperate marine fish. Avoid keeping with smaller, docile fish or invertebrates that could be prey.
- Requisitos especiais: Requires a large, well-established temperate marine aquarium with ample live rock for hiding and foraging. Excellent filtration and strong water movement are essential. A deep sand bed is beneficial as they may bury themselves at night or when stressed. Not suitable for typical tropical reef aquariums due to temperature requirements.

Fatos principais
Sex Changebehavior
Ballan Wrasse are protogynous hermaphrodites, meaning they are born female and can later change sex to male. This is a common reproductive strategy among wrasses.
Cleaner Fishbehavior
Juvenile Ballan Wrasse, and sometimes adults, are known to act as cleaner fish, removing parasites from other larger fish species. This behavior is also exploited in aquaculture, where they are used to control sea lice on farmed salmon.
Nest Buildingbehavior
Male Ballan Wrasse build elaborate nests from seaweed and algae, often in crevices or under overhangs, which they guard aggressively during the breeding season.
Longevityrecord
Ballan Wrasse are relatively long-lived for a coastal fish, with individuals known to reach ages of up to 29 years.
Color Variationinteresting
The extreme variability in coloration of the Ballan Wrasse is not only for camouflage but can also be influenced by age, sex, reproductive state, and even local habitat, making individual identification challenging at times.
Informações de segurança
Seguro- Nível de segurança: safe
- Venenoso: Não
- Comestibilidade: edible
- Observações de manuseio: Generally safe to handle, but like all fish, care should be taken to avoid fin spines, which can cause minor punctures. They have strong jaws and teeth, so avoid placing fingers near the mouth. Release promptly if caught for sport.
Espécies similares
Cuckoo Wrasse
Labrus mixtus
The Cuckoo Wrasse exhibits strong sexual dimorphism in coloration (males are bright blue and orange, females are orange with three black spots). Ballan Wrasse coloration is more mottled and less sexually dimorphic in distinct patterns, though males can be more vibrant.
Goldsinny Wrasse
Ctenolabrus rupestris
The Goldsinny Wrasse is much smaller (typically up to 18 cm) and has a distinct black spot at the base of the caudal fin and another on the anterior dorsal fin. Ballan Wrasse lacks these specific spots and is significantly larger.
Corkwing Wrasse
Symphodus melops
The Corkwing Wrasse is smaller (up to 25 cm) and has a distinct black spot on the caudal peduncle and a dark spot behind the eye. Its body shape is also generally more slender than the robust Ballan Wrasse.
