''Ophioviridae'' is a family of viruses characterized by an elongated and highly filamentous and flexible nucleocapsid with helical symmetry. The protein capsid is non-enveloped and has a constant diameter of 1500–2500 nm and a width of 3 nm, or 9 nm. The capsids form kinked circles, which can collapse to form linear duplex structures, much like a spring. The entire genome is 1100–1200 nucleotides long.〔ICTVdB Management (2006). 00.094.0.01.
