The biomechanics Ophiuroid tube-feet

Nature, 2020
The radial water-vascular system of ophiuroids shows two kinds of hydraulic mechanism; one is concerned with the retraction and extension of the tube-feet, the other with their operation as effector-organs. At least in amphiurids, tube-feet are fully extended by pressure developed in the radial canal.

The fine structure of the sperm of a holothurian and an ophiuroid

Journal of Morphology, 1976
AbstractThe fine structure of the mature sperm of the holothurian, Cucumaria miniata, and the ophiuroid, Ophiopholis aculeata, is described with particular reference to their acrosomal and centriolar satellite complexes, and compared to the sperm of other echinoderms.In Cucumaria, the acrosome is in the form of a diffuse acrosomal vesicle.

A pycnogonid-ophiuroid association

Marine Biology, 1979
Three species of the ophiuroid genus Ophiocoma (O. doederleini de Loriol, O. pica Muller and Troschel and O. erinaceus Muller and Troschel) are host to the pycnogonid Anoplodactylus ophiurophilus Stock n.sp. on Aldabra atoll, Seychelles Islands. Infestation levels of the host ophiuroids from 3 localities differed markedly according to species, and lay ...
