 Rhabdosomes, rod-shaped bodies found in the cytoplasm (approximately 3 µm in length and 0.25 µm), have been observed in "Ornithocercus" species.They’re thought to function in prey capture as trichocysts although no signs of emission have ever been observed.The observation of a cytosome with a microtubular strand was used as evidence of potential food uptake via the peduncle.
