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

Aquest tipus de taur\u00f3, de cos gruixut i cil\u00edndric, t\u00e9 una llargada m\u00e0xima de 310 cm. Tot i aix\u00f2, presenten un cert dimorfisme sexual, on els mascles arriben a la maduresa sexual quan arriben als 1,5 metres i les femelles en arribar als 200-220 cm.<\/p>\n\n\n\n

El cap, que el tenen aplanat dorsoventralment, presenta una boca gran i arquejada i uns ulls arrodonits sense membrana nictitant. Pel costat del cos es pot observar uns espiracles diminuts i una l\u00ednia lateral ben pronunciada que acaba en un morro allargat i bulb\u00f3s.<\/p>\n\n\n\n

Pel que respecta a les aletes, les dues aletes dorsals s\u00f3n molt semblants: petites (for\u00e7a m\u00e9s que les pelvianes) i arrodonides, i es troben molt juntes en posici\u00f3 molt endarrerida, properes a la cua. Les pectorals tenen forma trapezoidal i s\u00f3n tamb\u00e9 petites, gaireb\u00e9 de la mateixa mida que les pelvianes. L’aleta caudal acaba en punta, sense l\u00f2bul terminal; el l\u00f2bul inferior est\u00e0 molt poc marcat.<\/p>\n\n\n\n

La caracter\u00edstica m\u00e9s distingible d’aquest taur\u00f3 \u00e9s la pres\u00e8ncia de grans denticles d\u00e8rmics per tot l’organisme. Aquestes estructures poden tenir una al\u00e7ada de 10 mm i organitzar-se en grups de 2-10, formant plaques de 25\u202fmm, o b\u00e9 estar sols. A la pell tamb\u00e9 presenten una gruixuda capa de mucus d’olor fastig\u00f3s.<\/p>\n\n\n\n

Ells s’alimenten succionant, gr\u00e0cies a la gran faringe que tenen. Es poden alimentar de taurons m\u00e9s petits (incloent-hi el peix espin\u00f3s, Squalus acanthias), peixos ossis (incloent-hi marupa, bagres i peixos sargantana) i crancs.<\/p>\n\n\n\n

Aquesta esp\u00e8cie \u00e9s viv\u00edpara aplacent\u00e0ria, on els cadells acabats de n\u00e9ixer ja mesuren 40-50 cm de llarg. A m\u00e9s els embrions ja comencen a desenvolupar petites espines situades dins de fosses obertes de la pell.<\/p>\n<\/div>\n\n\n\n

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

Aquesta esp\u00e8cie es pot trobar vivint en el fons del tal\u00fas continental o insular, entre els 400-900 metres de profunditat. L’h\u00e0bitat t\u00edpic \u00e9s el fons tou o les roques de la regi\u00f3.<\/p>\n<\/div>\n\n\n

ESTAT DE CONSERVACI\u00d3:<\/strong><\/p>\n\n\n\n

Segons la llista vermella de la IUCN, l’esp\u00e8cie es troba En Perill d’Extinci\u00f3 (EN<\/strong>). Les seves poblacions van decreixent per moments principalment a causa de la pesca accidental.<\/p>\n<\/div>\n\n\n\n
