Carcharhiniformes
>> Classification > Ordre des Carcharhiniformes > La famille des Carcharhinidés
Il s'agit du groupe de requins dominants. Ils abondent sous les tropiques et sont très communs dans les eaux tempérées des plateaux continentaux. Certaines espèces constituent la majorité des requins du large. Le requin de fond type possède un museau allongé, une fente buccale qui s’étend jusqu’en arrière des yeux, une nageoire anale et deux nageoires dorsales sans épines. Les yeux disposent d’une paupière nictitante inférieure mobile, actionnée par des muscles particuliers. Les formes dentaires sont variables : petites, aplaties ou cuspidées, plus ou moins élancées ou en lame. Les requins de fond n’ont pas de dents postérieures broyeuses.
