False col SEM of nematode worm on sample of peat

False-colour scanning electron micrograph of a nematode worm on a sample of peat. The micrograph shows the layer of "green slime" which often appears on peat & other organic surfaces. The slime consists predominantly of single-celled green algae (spheres), which colour is green. The small rectangular objects are diatoms, another type of algae. The cellular structure of the underlying peat, which is predominantly Sphagnum moss partially preserved by waterlogging, is also visible. Nematodes occur in vast numbers in soil, sea & fresh water, & as plant & animal parasites; 80, 000 species are known. Magnification: x130 at 6x4.5cm size, x70 at 35mm size
