Resumen:
Acantharia are planktonic, free living, exclusively marine protozoa, ranging in size from 0.05-5 mm in diameter. Like several other marine protists (Radiolaria, Heliozoa), acantharians have axopodia: long, radiating processes used for capturing prey (Fig. 1, 2). Their distinguishing features are: (1) a skeleton of strontium sulfate (SrSO4), or celestite, based on a general plan of 10 diametral or 20 radial spicules arranged in a regular pattern called Müller's law ($Müller, 1859; Fig. 3, 4); (2) cell body covered with an outer pellicle, the periplasmic cortex (Fig. 5); (3) the myonemes, contractile filaments grouped around the spicules (Fig. 5).
