[[FishBase]] recognizes four [[species]] in the genus.<ref name=FishBase>{{FishBase genus | genus = Arapaima| month = August | year = 2013}}</ref> In addition to these, evidence suggests that a fifth species, ''A. arapaima'', should be recognized (this being the widespread, well-known species, otherwise included in ''A. gigas'').<ref name=Stewart2013a/><ref name=Stewart2013b/><ref name=Dawes/><ref>Clarke, M.

These fish are widely dispersed and do not migrate, which leads scientists to suppose that more species are waiting to be discovered in the depths of the Amazon Basin harbors. Sites such as these offer the likelihood of diversity.<ref name="Arantes">{{cite journal | last1 = Arantes | first1 = Caroline C. | last2 = Castello | first2 = Leandro | last3 = Cetra | first3 = Mauricio | last4 = Schilling | first4 = Ana | title = Environmental Influences on the Distribution of Arapaima in Amazon Floodplains | journal = Environmental Biology of Fishes | year = 2013 | volume = 2011 | issue = 10–11 | pages = 1257–267 | doi = 10.1007/s10641-011-9917-9 | bibcode = 2013EnvBF..96.1257A | s2cid = 9980805 }}</ref>
