'''''Tambja''''' is a genus of colorful sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Polyceridae.<ref name="WoRMS">MolluscaBase (2018).

==Biology== These nudibranchs feed on bryozoans. They have a radula which bears a rachidian tooth whose upper margin is either smooth or notched; the lateral tooth has two crowns, and the other teeth are so flat as to resemble plates.<ref name="Pola2006">{{Cite journal | last1 = Pola | first1 = M. | last2 = Cervera | first2 = J.
