Phaeosphaerida is an order of cercozoans in the class Phaeodarea.
Ernst Heinrich Philipp August Haeckel was a German zoologist, naturalist, eugenicist, philosopher, physician, professor, marine biologist and artist. He discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms and coined many terms in biology, including ecology, phylum, phylogeny, and Protista. Haeckel promoted and popularised Charles Darwin's work in Germany and developed the influential but no longer widely held recapitulation theory claiming that an individual organism's biological development, or ontogeny, parallels and summarises its species' evolutionary development, or phylogeny.
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. They show gametic meiosis.
Phaeodarea or Phaeodaria is a group of amoeboid cercozoan organisms. They are traditionally considered radiolarians, but in molecular trees do not appear to be close relatives of the other groups, and are instead placed among the Cercozoa. They are distinguished by the structure of their central capsule and by the presence of a phaeodium, an aggregate of waste particles within the cell.
Tobias Barreto de Meneses was a Brazilian poet, philosopher, jurist and literary critic. He is famous for creating the "Condorism" and revolutionizing Brazilian Romanticism and poetry. He is patron of the 38th chair of the Brazilian Academy of Letters.
Aulosphaera is a genus of Cercozoa. The genus contains bioluminescent species. It one of two known bioluminescent phaeodarean genera, the other being Tuscaridium. The described bioluminescent species is Aulosphaera triodon Haeckel, 1887.
Spongodiscidae is a family of radiolarians in the order Spumellaria. According to the original description by Ernst Haeckel, members of the family have a flat discoidal shell, in which a simple spherical central chamber is surrounded by an irregular spongy framework.
Phaeogromida is an order of cercozoans in the class Phaeodarea.
Phaeocalpida is an order of cercozoans in the class Phaeodarea.
Castanellidae is a family of cercozoans in the order Phaeocalpida.
Tuscaroridae is a family of cercozoans, single-celled eukaryotes in the order Phaeocalpida.
Circoporidae is a family of cercozoans, single-celled eukaryotes in the order Phaeocalpida.
Phaeocystida, also known as Phaeocystina, is a group of cercozoans in the class Phaeodarea. It was first described by Ernst Haeckel in 1887 and treated traditionally as a suborder, but later was raised to order level until Cavalier-Smith's classification lowered it again to suborder level. It belongs to the order Eodarida, characterised by simpler silica skeletons or a lack thereof.
Aulacanthidae is a family of cercozoans in the order Phaeocystida.
Phaeodendrida is an order of cercozoans in the class Phaeodarea.
Coelodendridae is a family of cercozoans in the order Phaeodendrida.
Aulosphaeridae is a family of cercozoans in the order Phaeosphaerida.
Clathrocyclas is a genus of radiolarians in the family Theoperidae.
Amphoriscus is a genus of calcareous sponges in the family Amphoriscidae.
Cystonectae is a suborder of siphonophores. It includes the Portuguese man o' war and Bathyphysa conifera.
Actinommidae is a family of radiolarians.
