Kofodiniaceae Leptodiscaceae Noctilucaceae Protodiniferaceae The Noctilucales are an order of marine dinoflagellates.

They differ from most others in that the mature cell is diploid and its nucleus does not show a dinokaryotic organization.

Noctilucales reproduce mainly by fission, but sexual reproduction also occurs.

Each cell produces numerous gametes, which resemble more typical athecate dinoflagellates and have the dinokaryotic nuclei.

Evidence suggests that they diverged from most other dinoflagellates early on, and they are generally placed in their own class.
