[1] It was placed into its own family, Odaraiidae by Simonetta and Delle Cave in 1975,[2] which has been used to include other genera of bivalved Cambrian arthropods.

Odaraiidae is currently placed within Hymenocarina, which includes many other mandible bearing (when preserved) bivalved Cambrian arthropods.

The head has a pair of large mandibles nearly as long as they are wide, the ends of which are covered in pointed "teeth", with setae also being present.

Just posterior the mandibles are another pair of appendages, probably maxillae, which are made up of seven or eight podomeres (segments), the final segments of which are covered in a significant number of setae (hair-like structures) At the end of the mouth furthest from the eyes, there is an unpaired element at the midline, called the "central tooth", which is highly sclerotized.

A central gut canal runs through the body, with the anus being located at the terminal trunk segment.
