Nautilus pompilius Linnaeus, 1758

Nautilus pompilius (nomeada, em inglês, emperor nautilus, pearly nautilus e chambered nautilus; em francês, nautile flammé; em espanhol, nautilo común) é uma espécie de molusco cefalópode nectônico marinho do Indo-Pacífico, pertencente à família Nautilidae e à ordem Nautilida, sendo classificada por Carolus Linnaeus, em 1758, na sua obra Systema Naturae, junto à sua determinação de gênero (Nautilus). Possui o comprimento máximo de 25,4 cm, sendo a espécie maior, mais conhecida e mais bem distribuída destes moluscos; dotada de um umbílico preenchido por uma concreção, além de sua concha possuir marcações de cor avermelhada se estendendo por quase toda sua superfície, que varia, mas geralmente é constituída de listras irregulares que se irradiam do centro para a parte externa; porém o terço terminal de suas voltas é branco.
