Takayama helix is a species of dinoflagellates with sigmoid apical grooves first found in Tasmanian and South African waters.[1] It contains fucoxanthin and its derivatives as its main accessory pigments.
Takayama helix has an apical groove being practically straight while still clearly bent. It possesses one ventral pore. It has various peripheral, strap-shaped, spiraling chloroplasts with unique pyrenoids and an ellipsoidal nucleus.[1]
