Ventrifilosa (from
ventral side for feeding. Because of their mixture of amoeba and flagellate characteristics, they are amoeboflagellates. Members of this group are the Imbricatea, Sarcomonadea and Thecofilosea.[1]
Morphology
Protists in the group Ventrifilosa ancestrally have a rigid extracellular
phaeodarian.[2]
The group includes descendants that have lost or modified some of these characteristics. For example, some have lost their pseudopods (such as the
Phaeodaria). The loss of flagella and scales has occurred in this group several times independently through evolution.[2][3]
Taxonomy
The superclass Ventrifilosa was first described in 2012 by
sarcomonads were excluded. Later, in 2018, it was expanded to include Sarcomonadea, which belonged to the superclass Eoglissa before this change.[1]
The current classification of Ventrifilosa recognizes 3 classes, 20 orders and 60 families.[1]
