Gephyrocapsa ornata


Classification: Coccolithophores -> Isochrysidales -> Noelaerhabdaceae -> Gephyrocapsa -> Gephyrocapsa ornata
Sister taxa: G. oceanica, G. muellerae, G. ornata, G. ericsonii, G. sp elevated bridge, G. caribbeanica, G. omega, G. lumina, G. small, G. sp.,

Taxonomy:

Citation: Gephyrocapsa ornata Heimdal, 1973
Rank: Species
Notes & discussion: Although rare this seems to be a discrete species. It has a very distinctive morphology and does not seem to intergrade with other species.

Distinguishing features: Similar to G. ericsonii but larger, with teeth around tube, much higher bridge; consistently high angle (within 70-80° from short axis).
