Resumo: 	The teeth of nearly all supraspecific taxa of squaliformes are described and illustrated by SEM photos. The tooth morphology allows a direct assignment to all these taxa and some proposals of taxonomic adjustments. The results support opinions of other authors, that Echinorhinidae represent a separate order, Oxynotidae coincide odontologically with Squalidae; Squalid genera could be grouped into 8 subfamilies, 4 of which could not be defined hitherto; &lt;i&gt;Centroselachus&lt;/i&gt; Garman, 1913 is confirmed and should be revalidated; significant odontological differences do not exist between &lt;i&gt;Cirrhigaleus&lt;/i&gt; and &lt;i&gt;Squalus, Lepidorhinus&lt;/i&gt; and &lt;i&gt;Centrophorus, Scymnodon&lt;/i&gt; and &lt;i&gt;Scymnodalatias&lt;/i&gt;, neither between &lt;i&gt;Squaliolus&lt;/i&gt; and &lt;i&gt;Heteroscymnoides&lt;/i&gt; and &lt;i&gt;Euprotomicrus&lt;/i&gt; on the other hand; 2 subgenera appear to be justified for the 3 species of &lt;i&gt;Somniosus: Somniosus (Somniosus)&lt;/i&gt; and &lt;i&gt;Somniosus (Rhinoscymnus)&lt;/i&gt;. An odontological key is given for all these supraspecific taxa.
