Cephalodiscus planitectus is a sessile hemichordate belonging to the order Cephalodiscida.
[1] It is found at a depth of 100–300 metres off the island of Jōgashima, Sagami Bay, Japan.
[1] There are three pairs of arms with tentacles.
[1] Cephalodiscus planitectus is the most divergent of all Cephalodiscus species, with Miyamoto, Nishikawa and Namikawa (2020) suggesting that it constitutes a sister group to all existing Cephalodiscus species.
