Fig. 1. Zoelucasa sablensis. a – diagrammatic representation of cellular components, where: af – anterior flagellum, tf – trailing flagellum, S – scales, N – nucleus, n – nucleolus; b – external arrangement of scales; c, d – SEM images of whole, dried cells showing covering of scales and flagella; e – DIC image of cell showing optical section of the scale layer (arrows); f – nucleus (N); g, h – nucleus (large arrow) and parallel flagellar insertion in anterior pocket (small arrows) of cells that have retracted to a posterior position within their loricae; i – trailing flagellum in a "swimming" cell; j – anterior pocket (larger arrow) and parallel emergence of two flagella (small arrows); k – diagrammatic representation of the zig-zag pattern of cell "swimming" movement; l, m – compressed cells showing the flagella (arrows) and disassociated scales around the cells (note the fractures of some scales in m); n–r – TEM images of scales.
