亞河豚科：修订间差异

'''亞河豚科'''（[[學名]]：Iniidae）是[[淡水豚]]的一個[[科 (生物)|科]]，於1846年由英國動物學家[[约翰·爱德华·格雷]]發表描述<ref name="TPBDB">{{cite web |url=http://paleodb.org/cgi-bin/bridge.pl?action=checkTaxonInfo&taxon_no=53142&is_real_user=1 |title=The paleobiology Database |accessdate=2019-05-11 |||}}</ref>

。本科的現生類群只有分布於[[南美洲]]的[[亞河豚屬]]，其下包含2-3種物種與若干[[亞種]]<ref name="Hrbek2014">{{Cite journal | last1 = Hrbek | first1 = Tomas | last2 = Da Silva | first2 = Vera Maria Ferreira | last3 = Dutra | first3 = Nicole | last4 = Gravena | first4 = Waleska | last5 = Martin | first5 = Anthony R. | last6 = Farias | first6 = Izeni Pires | editor1-last = Turvey | editor1-first = Samuel T. | title = A New Species of River Dolphin from Brazil or: How Little Do We Know Our Biodiversity | url = http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0083623 | doi = 10.1371/journal.pone.0083623 | journal = [[PLOS ONE]] | volume = 9 | pages = e83623 | date = 2014-01-22 | pmid = 24465386 | pmc = 3898917 | access-date = 2019-05-11 | | | }}</ref>，另外還有數個已[[滅絕]]的[[屬]]。本科類群的外形與[[海豚]]有所差異，可能有助其[[適應]]淡水中的生活<ref name="Hamilton2001">Hamilton, Healy, et al.
