Archigetes (flatworm)
The genus ''Archigetes'' Leuckart, 1878 is unique among all tapeworms in that its species can mature in invertebrate hosts (Oligochaeta), in contrast to all other cestodes which have a vertebrate host. All five species were described as plerocercoids in oligochaetes, but two of them were also described as adults in cypriniform fishes. Species According to WoRMS, there are five valid species: * ''Archigetes brachyurus'' Mrázek, 1908 * ''Archigetes cryptobothrius'' Wiśniewski, 1928 * ''Archigetes iowensis'' Calentine, 1962 * ''Archigetes limnodrili'' (Satyu Yamaguti, Yamaguti, 1934) Kennedy, 1965Kennedy CR. 1965.

Animal
Animals are multicellular, eukaryotic organisms in the Biology, biological Kingdom (biology), kingdom Animalia (). With few exceptions, animals heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, have myocytes and are motility, able to move, can reproduce sexually, and grow from a hollow sphere of Cell (biology), cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million extant taxon, living animal species have been species description, described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and biological interaction, interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as ...
