Reassessment of the classification of the Ophiuroidea (Echinodermata), based on morphological characters. I. General character evaluation and delineation of the families Ophiomyxidae and Ophiacanthidae

Zootaxa, 2019
Most of the taxonomically reliable internal and microstructural characters (e.g. jaws, dental plate, genital plates, vertebrae) of the recent Ophiuroidea are studied using SEM on a broad comparative basis for the first time, including examination of the ...

[Types of locomotion in Ophiuroidea].

Neirofiziologiia = Neurophysiology, 1976
Locomotor movements of two species of ophiura from the Sea of Japan: Ophiura sarsi vadicola Djakonov and Amphipholis kochii Lütken, were filmed. Ophiura sarsi moves by means of two symmetric pairs of arms which perform rhythmical rowing movements, the fifth arm is passive and directed backwards.

Arm autotomy in brittlestars (Echinodermata: Ophiuroidea)

Journal of Zoology, 1978
Although ophiuroid arm shedding has long been accepted as an example of autotomy, there has been little investigation of the phenomenon to substantiate this. This paper describes the outwardly visible aspects of autotomy and the function of the internal components of the arm during detachment.
