Cephalodiscus is a genus of hemichordates in the family Cephalodiscidae of the order Cephalodiscida.
==Description== All known species live in a secreted coenecium attached to a rock substrate. Unlike Rhabdopleura, Cephalodiscus species do not form large colonies and are only pseudocolonial, but they do share a common area with individual buds for each zooid. Cephalodiscus zooids are also more mobile than their Rhabdopleura counterparts, and are able to move around within tubaria. Cephalodiscus zooids can be produced via asexual budding. There are a few pairs of tentacled arms, whereas Rhabdopleura has only one pair of arms.
