They share two key characters: a beak-like anterior rostrum interrupting the perioral kineties, and peculiar cytoplasmic organelles named Müller vesicles.

[3] The term Loxodidae derives from the ancient Greek λοξός (loxós), meaning "oblique, tilted".

It contains a Müller body, which comprises mineral concretions in an organic matrix bounded by a membrane, that is suspended in a vacuole by a stalk.

The stalk is about 0.3–0.4 μm thick, and contains microtubules that connect the Müller body with the adjacent kinety, which is believed to help transmit the sensory signal to the rest of the cell.

[9] Molecular phylogeny based on sequences of the SSU rRNA gene indicates that Remanella and Loxodes branch together into a monophyletic family Loxodidae.
