''Abeoforma whisleri'' is a single-celled eukaryote that belongs to the Ichthyosporea clade, a group of protists closely related to animals.
''A. whisleri'' was isolated from the digestive tract of a marine invertebrate, specifically the filter-feeding mussel ''Mytilus'' sp''.'' ''A. whisleri'' has a very complex life-cycle, yet to be resolved. It includes several different cell stages, ranging from amoeboidal, hyphal-like and plasmodial stages, which can present filopodia-like (pseudopodia) structures. They also present coenocytic spherical stages with prominent vacuoles and several nuclei. All of those stages undergo dramatic morphological changes and have a cell wall (except for the amoeboid stage).

Applications
![Abeoforma whisleri-2](https://upload.wikimedia.org/wikipedia/commons/0/06/Abeoforma_whisleri-2.jpg)
A. whisleri can easily be cultured axenically in marine broth medium. Given its phylogenetic position as a close unicellular relative of animals and its high capacity to modify cell morphology, ''A. whisleri'' could potentially provide important insights both into the origin of multicellular animals and into the control of cell shape in eukaryotes.
