The Apicomplexa is the only large taxonomic group whose members are entirely parasitic and is, therefore, presumably of major interest to parasitologists. We might, for example, expect that we know a great deal about the biology of the group by now and that we have a clear phylogenetic framework within which to organize that knowledge. It might thus come as a surprise to learn that in terms of biodiversity, the Apicomplexa is actually the least-known group of all. Furthermore, the taxonomic framework for the Apicomplexa is rather tenuous in many respects. This situation is unlikely to change in the short term.
顶复门是唯一成员全为寄生生物的大型分类群，因此大概是寄生虫学家主要感兴趣的对象。例如，我们可能期望到目前为止我们对该类群的生物学已经了解很多，并且我们有一个清晰的系统发育框架来组织这些知识。然而，得知就生物多样性而言，顶复门实际上是所有类群中最不为人所知的，可能会让人感到惊讶。此外，顶复门的分类框架在许多方面相当薄弱。这种情况在短期内不太可能改变。
