2. Caenorhabditis elegans, as the roundworm is properly known, is a tiny, transparent animal just a millimeter long.

4. 25 Caenorhabditis elegans, as the roundworm is properly known, is a tiny, transparent animal just a millimeter long.

5. Also, Cilium length can be modified, for example during fertilization in Chlamydomonas and during Caenorhabditis elegans dauer development (Albert and Riddle, 1983; Mesland et al., 1980)

6. In Caenorhabditis elegans, Amphid sensory organs in the head also consist of sensory neurons and glia-like support cells (Amphid socket and Amphid sheath cells).
