Dagiti subgrupo
  • Ichthyosporea (= Mesomycetozoea)
  • Corallochytrium
  • Filasterea
  • Choanoflagellata
  • Metazoa (ay-ayup)

Ti holozoa ket isu ti grupo dagiti organismo a mangiraman dagiti ayup ken ti kaasitganda nga agmaymaysa a selula a kabkabagian, ngem saan a mairaman dagiti fungus.[1][2][3] [4] Ti holozoa ket isu pay ti daan a nagan para iti henero ti tunicate Distaplia.[5]

Gapu ta ti Holozoa ket klado a mairaman dagiti amin nga organismo nga as-asideg a kabagian dagiti ayup ngem dagiti fungus, adda met dagiti mannurat a kaykayatda ti mangbigbig kadagiti grupo ti parapiletiko a kas ti Choanozoa, a kaaduan kadagitou ket buklen ti Holozoa a saan a mairaman dagiti ayup.[6]

Dagiti kaaduan nga ammo a holozoa, malaksid kadagiti ayup, ket dagiti choanoflagellate, a kapdpada unay dagiti kuelio a selula dagiti espongha, ken isunga naiteoria a maikabagian dagitoy kadagiti espongha uray idi maika-19 a siglo. Ti Proterospongia ket maysa a kas pagarigan ti kolonial a choanoflagellate a mabalin a makaipalawag ti tinaudan dagiti espongha.

Ti pannakaikabagian dagiti sabali nga agmaymaysa a selula a holozoan ket nangrugi laeng a mabigbigan idi tawtawen ti 1990.[7] Ti grupo a kaaduan a parasitiko a sebbangan a tinawatawagan ti Icthyosporea wenno Mesomycetozoea ket sagpaminsan a naigrupo kadagiti sebbangan iti Mesomycetozoa (kitaen ti paggiddiatan iti pagpatingaan). Dagiti henero ti amoeboid ti Ministeria ken ti Capsaspora ket mabalin a maikaykaysa iti grupo a tinawtawagan ti Filasterea babaen ti estrukturada dagiti kasla kuerdas a pseudopod. A kakuyog dagiti choanoflagellate, filasterean ket mabalin dagitoy nga asideg a kabagian dagiti ayup, ken ti maysa a panagusig ket nangigrupo kadagitoy a kas klado ti Filozoa.[3]
