Tambja

Tambja is a genus of colorful sea slugs, dorid nudibranchs, shell-less marine gastropod mollusks in the family Polyceridae.

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.
