    The axial complex of O. robusta is located in the same interradius as in all other echinoderms. According to generally approved notation, this interradius is usually indicated as interradius CD (see for example, Ubaghs 1967; Goldschmid 1996 ).
    In the main components, the axial complex of Ophiuroidea fits other Asterozoa. But there are some important differences. The stone canal connects with the ambulacral ring from the outside, not from the inside. The somatocoelomic perihaemal ring is closer to the mouth than the axocoelomic ring.
    The role of the haemal system of ophiuroids and other echinoderms remains mysterious. It is involved in the storage and distribution of nutrients (Ferguson 1985; Byrne 1988 ). It is possible that haemal fluid could be manipulated to vary the viscosity of the echinoderm extracellular matrix (Byrne 1988, 1994 ).
    Ophiuroids are believed to be closely related to the Asteroidea (Smith 1940; Ivanova-Kazas 1978; Goldschmid 1996; Ruppert et al. 2004) and to the Echinoidea (MacBride 1907; Narasimhamurti 1933 ).
