DESCRIPCI\u00d3:<\/strong><\/p>\n\n\n\n

Es tracta d\u2019un peix alt i comprimit, de cos ovalat i colors platejats i vermells rosats. Mesura entre 20 i 50 cm de longitud. T\u00e9 un cap gran amb una boca superior; tamb\u00e9 est\u00e0 recobert de cavitats mucoses separades per espines i cobertes per mucoses. Aquestes, al voltant dels seus grans ulls, dona lloc al seu nom com\u00fa. Tamb\u00e9 t\u00e9 una s\u00e8rie d\u2019entre 11 a 14 r\u00edgids escudets al ventre, que s\u00f3n escames modificades, entre les aletes pelvianes i l\u2019anal. Presenta una espina al preopercle. La l\u00ednia lateral \u00e9s ben distingida.<\/p>\n\n\n\n

Es creu que els escudets poden oferir una funci\u00f3 protectora contra els seus depredadors. Pel que fa a les cavitats mucoses, els autors difereixen en la utilitat que aquestes ofereixen al peix. Es creu que el mucus que contenen el podrien fer servir per notar vibracions a l\u2019aigua (com si es tract\u00e9s de la l\u00ednia lateral) o b\u00e9, pot ser una l\u00ednia de defensa contra bacteris i altres par\u00e0sits.<\/p>\n\n\n\n

Es tracta d\u2019un ca\u00e7ador oportunista que s\u2019alimenta de petits crustacis, tot i que tamb\u00e9 s\u2019ha observat un comportament m\u00e9s selectiu en ambients amb abundants preses potencials.<\/p>\n<\/div>\n\n\n\n

HABITAT I ZONA DE DISTRIBUCI\u00d3:<\/strong><\/p>\n\n\n\n

Aquesta esp\u00e8cie es troba distribu\u00efda globalment, pr\u00f2xim a les plataformes continentals; habita al bentos dels talussos i seamounts del mar Balear. Es poden trobar en un ampli rang batim\u00e8tric, d\u2019entre 100 metres i 1400. Aix\u00ed i tot, les formes juvenils acostumen a habitar aig\u00fces m\u00e9s someres, mentre que els adults baixen per sota dels 500 m, essent m\u00e9s abundants entre els 600 i 800 m.<\/p>\n<\/div>\n\n\n\n
