据估计，藻类包括 30,000 至超过 100 万种。这里尝试使用在线分类数据库 AlgaeBase (http://www.algaebase.org) 中包含的门和类中的物种数量来获得更准确的估计。尽管对于哪些生物体应被归为藻类以及在不同藻类门和纲的背景下物种是什么存在不确定性，但保守的方法导致估计有 72,500 个藻类物种，其中 44,000 个藻类的名称可能已公布，并且迄今为止 AlgaeBase 已处理了 33,248 个名称（2012 年 6 月）。一些已发表的估计硅藻数量超过 200,000 种，这意味着每一种其他藻类就有 4 到 5 种硅藻。人们对全世界有能力改进和完成必要的系统研究的分类学家的衰落和潜在灭绝表示担忧。
Algae have been estimated to include anything from 30,000 to more than 1 million species. An attempt is made here to arrive at a more accurate estimate using species numbers in phyla and classes included in the on-line taxonomic database AlgaeBase (http://www.algaebase.org). Despite uncertainties regarding what organisms should be included as algae and what a species is in the context of the various algal phyla and classes, a conservative approach results in an estimate of 72,500 algal species, names for 44,000 of which have probably been published, and 33,248 names have been processed by AlgaeBase to date (June 2012). Some published estimates of diatom numbers are of over 200,000 species, which would result in four to five diatom species for every other algal species. Concern is expressed at the decline and potential extinction of taxonomists worldwide capable of improving and completing the necessary systematic studies.
