Decapoda

Ny Decapoda dia filaharana lehibe ao amin' ny Crustacea, ao amin' ny kilasy Malacostraca,  manana tongotra 5 ankavia sy 5 ankavanana. izay ahitana ny fozan-dranomamy, ny drakaka, ny makamba, ny orana, ny fozaorana, ary hatramin' ny langosta. Tombanana ho misy karazana efa ho 15 000 eo ho eo ao amin' ny sokajy 2 700 eo ho eo, misy karazana fôsily 3 300 eo ho eo ity filaharana ity.
Biby mpihinan-kena, mpihinana fatim-biby, na mpihinana poti-javatra avy amin' ny zavamananaina ny Decapoda. Miana an-dranoasina ny ankamaroany. Ny sasany, toy ny orana, dia miaina anaty ranomamy, ary ny hafa, toy ny fozam-boanio, dia miaina an-tanety eny amin' ny toerana mando.vignette|Karazana Decapoda efatra: Grapsus grapsus, Birgus latro (fozam-boanio), Lysmata amboinensis, Homarus gammarusAraka ny mahazatra, araka ny endriky ny kibony,  dia nozaraina roa ny Decapoda:
 Macroura: manana kibo lava, toy ny orana, ny fozaorana, ny makamba, ny patsa, sns;
 Brachyura: manana kibo fohy ary matetika miforitra eo ambanin' ny tratrany, toy ny foza sy ny drakaka.
Misy anefa vondron-karazana izay manalasala ny fanasokajiana azy: Charassocarcinus Van Straelen, 1925vignette|193x193px|Cancer bellianus (Pleocyemata)|ankaviaTeo aloha izy ireo dia nosokajiana ho zana-pilaharana roa antsoina hoe Natantia ("milomano") sy Reptantia. ("mandady")

Mizara ho zana-pilaharana roa, mifototra amin' ny endriky ny sagogany sy ny fomba fitondrany vohoka ny Decapoda:
 Dendrobranchiata Bate, 1888 (manatody anaty rano);
 Pleocyemata Burkenroad, 1963 (mikotrika ny atodiny eo ambanin' ny kibonyvignette|185x185px|Aristaeomorpha foliacea, (Aristeidae - Dendrobranchiata)|ankavia
