Acantharian microtubules, animation. Acantharia are a type of marine protozoa with an intricate and complex internal skeleton made up of spicules of strontium sulphate (green). Around this is an external layer of highly vacuolated buoyant protoplasm, from which radiate numerous microtubules known as pseudopodia (purple). Here these microtubules are seen extending and contracting. | |
