Along with Xenophyophores they dominate the macro- and megabenthic fauna in the deep sea and are commonly referred to as "giants protists".

[2] The komokiacean body consists of a central tube with several branching tubules that contain diffuse protoplasm and numerous waste pellets (stercomata).

[3] However, in other forms such as that of the genus Lana the body is a loose mass of branching tubules with no centre of organization.

[4] Komokiacea serve often as a substrate for benthic meiofaunal organisms such as foraminifera, fungi and other deep-sea taxa.

High numbers of morphospecies have been described from the Southern Ocean (50),[6] and the North-east subequatorial Pacific (102),[7] which suggests that they are a significant constituent of benthic foraminiferal diversity in the deep sea.
