Els individus juvenils s\u00f3n pel\u00e0gics fins a assolir entre 50 i 60 cm, moment en qu\u00e8 esdevenen demersals i habiten profunditats d’entre 40 fins als 600 m. Els adults prefereixen els h\u00e0bitats rocosos i els restes de naufragis submarins, entre els 100 i 200 metres de profunditat.<\/p>\n\n\n\n

El podem a l’Atlantic est, des de Noruega fins al sud d’\u00c0frica. Tamb\u00e9 es pot trobar al Mediterrani, a l’oest de l’oce\u00e0 \u00cdndic i al sud-oest del Pac\u00edfic.<\/p>\n<\/div>\n\n\n
